MongoDB has extended vector search and other capabilities to its self-managed database offerings — Enterprise Server and Community edition — to help developers build generative AI and agentic applications.

The same capabilities were added to its managed database offering — Atlas — in June 2023 with the same intent.

Both the Enterprise Server and Community Edition require users to manage their own deployments. The key difference: Enterprise needs a paid license, while Community Edition is free and open source.

The addition of vector search and new capabilities, according to the NoSQL document database provider, will help enterprises using these versions bypass the challenge of relying on external search engines or vector databases to build AI-driven applications, just like in Atlas.

The reliance on a fragmented, heterogeneous stack also introduced operational overhead along with complex extract, transform, and load (ETL) pipelines that were prone to synchronization errors, leading to higher costs, MongoDB said.

Typically, developers need vector search for building AI-driven applications as it is faster and provides more relevant results to a query presented.

Vector search uses mathematical representations to find and retrieve data based on contextual similarity, rather than searching for exact matches.

This ability to conduct similarity searches can also be used by developers to build retrieval-augmented generation (RAG) systems that enhance the reliability of large language models or agents based on them by grounding their outputs in verified enterprise data and content.

The addition of vector search to the self-managed offerings, according to MongoDB, also opens the door for enterprises to pair MongoDB’s native vector search with popular open-source frameworks like LangChain and LlamaIndex, making it easier to build (RAG) applications on self-managed infrastructure.

Industry analysts see this move as more than just a technical upgrade. Jason Andersen, principal analyst at Moor Insights & Strategy, views the new capabilities as part of MongoDB’s broader strategy to attract a wider customer base.

“Enterprise Server drives significant revenue for MongoDB,” Andersen said.

The NoSQL document database provider has been aggressively strategizing to garner more customers as all database providers continue to evolve vector search and other capabilities for building AI-based applications in their offerings.

While at one end, traditional database players, such as MongoDB, Google, etc., have added vector capabilities, specialty vector databases are adding additional features to make their products more easily consumable by non-experts.

When asked about the delay in releasing vector search to the self-managed offerings, Andersen pointed out that it could have been a business decision for the company to prioritize Atlas as it is their flagship offering.

Vector search and other capabilities added to the managed offerings are currently in public preview.

Over the last few years, Rust has evolved from a curiosity brewed up in a Mozilla employee’s lab to a strong contender for the next generation of system-native applications and bare-metal solutions. Those advances come from Rust providing its own toolchain and component management system—along with certain popular features and quirks.

This article is for developers new to Rust or considering it for future projects. We’ll walk through setting up a working environment in Rust, configuring an IDE, and making the most of Rust’s excellent application development toolset.

Understanding Rust releases

Rust’s toolchain consists of two key tools: rustup, a tool for keeping Rust itself up to date, and the Rust compiler, rustc. Because Rust is under constant development, its toolchain is designed to be easy to update.

Software projects are often provided via multiple release channels to keep the stable and beta versions of the code separate. Rust works the same way, offering three channels for toolchain updates:

• Stable: Major point releases, which emerge every six weeks or so.
• Beta: Candidates for the next major point release, which emerge more frequently.
• Nightly: The most immediate build, with access to cutting-edge features but no guarantees as to their stability.

As developer Karol Kuczmarski has pointed out, it’s best to think of the nightly Rust release as its own language. Some Rust features are only available in nightly Rust, and they can only be activated by special compiler directives. In other words, they won’t even compile on the beta or stable release channels.

There’s no guarantee the nightly features will be supported anywhere else, or ever again. However, many features eventually graduate out of the nightly channel and into beta and stable releases. (Compiling to WebAssembly, for instance, works in the stable version as of Rust 1.30.)

What does this mean for you as a developer? In short:

• Use a stable release for actual production work.
• Use beta releases to test current software against upcoming versions to see if anything may break in the upgrade.
• Only use nightly releases for sandboxed experiments with Rust’s newest features.

Choosing your Rust development platform

Rust supports all three major operating systems—Windows, Linux, and macOS—in both 32- and 64-bit incarnations, with official binaries for each. All three platforms are also supported on ARM64 processors.

A slew of other platforms also have official binaries, but they don’t have the same level of automated test coverage. These second-class platforms include ARMv6 and ARMv7 for iOS, Android, and Linux; MIPS Linux and MIPS64 Linux; 32-bit editions of x86 iOS, Windows, and Linux; and WebAssembly. Other platforms, like Windows XP or the experimental HaikuOS, are supported through unofficial builds.

Rust’s development team has stated that being broadly portable isn’t one of Rust’s missions. For example, although Rust is available on many ARM architectures, there is no guarantee that it will be officially supported on low-end hardware platforms.

That said, you should be able to find a supported Rust build for most common, mainstream use cases—namely, 32- and 64-bit Windows, Linux, and macOS.

Rust on Windows

If you’re planning to develop in Rust on Windows, keep your toolchains in mind. Rust supports two Windows toolchains:

• The native Microsoft Visual C (MSVC) ABI
• The Gnu ABI used by the GCC linker

Because almost all C/C++ software built in Windows uses MSVC anyway, you’ll want to use the MSVC toolchain most of the time. If you ever need GCC, it’ll most likely be for interoperating with third-party libraries built in Windows with GCC.

The good news is that Rust’s toolchain management system lets you keep both MSVC and GCC toolchains installed, and it lets you switch between them on a project-by-project basis.

Rust with WebAssembly

One of Rust’s compilation targets is WebAssembly, which lets you write in Rust and deploy to a web browser. WebAssembly itself is still rough around the edges, and so is Rust’s support for it. But if you’re ambitious and you want to get your hands messy, this guide details the process for compiling WebAssembly to Rust. Written by Rust and WebAssembly engineers, the book includes many real-world example scenarios, such as working with a canvas object in a browser, WebSockets, audio, and Web Workers.

Setting up the Rust toolchain

Rust provides an all-in-one installer and toolchain maintenance system called rustup. Download rustup and run it; it’ll obtain the latest versions of the Rust toolchain and install them for you.

The most critical tools maintained by rustup are:

• rustup itself: Whenever new versions of rustup or other tools are published, you can just run rustup update and everything will be updated automatically.
• rustc: The Rust compiler.
• Cargo: Rust’s package and workspace manager.

By default, rustup installs Rust from the stable release channel. If you want to use a beta or nightly version, you must install those channels manually (for example, by running rustup install nightly) and set Rust to use them by default (rustup default nightly). You can also manually specify which channel to use when compiling a Rust application, so you don’t have to set and reset the default every time you move between projects.

Foundry

You can also use rustup to install and maintain custom toolchains. These are typically used by unofficial, third-party builds of Rust for unsupported platforms, which usually require their own linkers or other platform-specific tools.

Another default assumption of Rust is that it stores Cargo files—the downloaded packages and configuration information—in a subdirectory of your user profile. In some cases, you may want that data on another drive where there is more room, or in a place that is more accessible. If you want Cargo to live somewhere else, you can relocate it manually after the setup is finished. Here are the steps:

1. Close down all programs that might be using Cargo.
2. Copy the .cargo directory in your user profile to where you want it to live.
3. Set the environment variables CARGO_HOME and RUSTUP_HOME to point to the new directory.
4. Set the PATH to point to the bin subdirectory of the new directory.
5. Type cargo to ensure Cargo is running properly.

Configuring your IDE for Rust

Despite Rust being a relatively new language, it’s already garnered strong support from many common IDEs. Developer Manuel Hoffman maintains a project to track the state of such support at the website areweideyet.com.

Making Rust work well with IDEs is an express goal of its development team, via a feature called the Rust Language Server (RLS). RLS provides live feedback about the code in question from Rust’s own compiler, rather than from a third-party parser.anguage Server (RLS). RLS provides live feedback about the code in question from Rust’s own compiler, rather than from a third-party parser.

Foundry

Here are the IDEs that support Rust as of this writing:

• Microsoft’s Visual Studio Code has a Rust language support extension created by Rust’s own developer tools team. This level of integration makes it one of the best-supported IDEs for Rust.
• Eclipse users can download a prepackaged edition of Eclipse for Rust development, or use the standalone Corrosion plugin for Eclipse Photon. However, neither have been updated since 2022.
• If you’re a fan of Emacs or Vim, other developers like you have written Rust-specific add-ons for both editors. Emacs has a Rust-specific mode, and Vim has a plugin to provide syntax highlighting and formatting. RLS support is available for both Emacs and Vim, but you must add and configure it manually.
• JetBrains has its own dedicated Rust IDE, RustRover.
• Sublime Text has Rust syntax support out of the box, and plugins provide deeper support for other features.

Creating your first Rust project

Rust projects are meant to have a consistent directory structure, with code and project metadata stored within them in certain ways. Code is stored in a src subdirectory, and details about the project are stored in two files in the project’s root directory, Cargo.toml (the project’s basic information) and Cargo.lock (an automatically generated list of dependencies). You can create that directory structure and metadata by hand, but it’s easier to use Rust’s own tools to do the job.

Rust’s Cargo tool manages both Rust projects and the libraries, or “crates,” they use. To spin up a new Rust project named my_project in its own directory, type cargo new my_project. (For C# developers working with .Net Core, think of the dotnet new command.) The new project appears in a subdirectory with that name, along with a basic project manifest—the Cargo.toml file—and a stub for the project’s source code, in a src subdirectory.

When you create a new project, a main.rs file is automatically created in the project’s src directory. This file contains a basic “hello world” application, so you can test out your Rust toolchain right away by compiling and running it.

Here’s the source code for that basic “hello world” application:

fn main() {
  println!(“Hello World!”);
}

To build and run the application, go to the project directory’s root and type cargo run. Note that by default, Cargo builds projects in debug mode. To run in release mode, use cargo run --release, or cargo run -r. Binaries are built in the project’s target/debug or target/release subdirectory, depending on which compilation profile you’re using.

Foundry

Working with Rust crates

Package management is a key part of any modern programming environment. To that end, Rust provides “crates,” which are third-party libraries packaged for distribution with Rust’s tools. You can find crates in the official Rust package registry, Crates.io.

If your project has a dependency on a particular crate, you need to specify that crate by editing the project’s Cargo.toml file. The standard way to do this is manually—that is, by simply editing Cargo.toml directly with a text editor. The next time the project is rebuilt, Rust automatically obtains any needed dependencies.

When you build a Rust project that depends on external crates, Cargo looks for those crates on Crates.io by default; you don’t need to obtain them manually. You can also refer to crates in your project by URL rather than by crate name, in case you need a crate that isn’t hosted in the registry, such as something from a private repository.

Note that some crates will only install and build on Rust’s nightly channel, because they use experimental features not available in other channels. If you’re on the release channel and you try installing such a crate, you won’t get any warning until the compilation fails. Crate documentation usually mentions whether it requires the nightly channel or not, so read up before you include, let alone compile.

Crates can come with binaries included. Some are command-line tools used in Rust development; others are general-purpose tools (such as ripgrep). To install one of these crates, just type cargo install . This isn’t the only way to distribute a binary created with Rust, but it’s a convenient way for Rust developers to obtain them as part of a workflow involving Rust tools.

Cross-compiling Rust to another platform

Because Rust supports multiple toolchains, even in the same Rust installation, you can compile Rust applications to a target operating system and environment that’s different from the one you’re compiling on.

Such cross-compiling requires a toolchain on the platform you’re working on that matches the target platform. Sometimes, as with cross-compiling to Linux on Windows, or vice versa, this involves little more than having the GCC linker. But other times, it’s more complex. If you want to cross-compile to macOS, for example, you need the Xcode IDE libraries to finish the job—cctools (Apple’s equivalent of binutils) and the macOS SDK.

Some third-party tools can help you work around these difficulties:

• Cross runs directly on a 64-bit x86 Linux host and provides what its creator describes as “zero-setup” cross-compiling to a wide variety of targets, including 64-bit Windows and MIPS.
• Trust is a Travis CI and AppVeyor template that can automatically publish binary releases of a Rust project. Trust can build for Linux, Windows, and macOS, although it requires the Travis CI and AppVeyor services. Your project also must be hosted on GitHub.
• The crossbuild project provides a multi-architecture Docker image that can be used to cross-build between all three major platforms.

Note that of these three tools, only Cross has been updated recently.

An easy way to get started with Rust

A good way to get your legs with Rust is to check out a third-party project and work on it locally. The easy way to do that is to make a Git clone of a Rust project’s repository. As long as the repo has a Cargo.toml file in its root, it’ll be recognized by Cargo.

One thing Cargo can’t do, at least not yet, is make a local clone of a crate by itself. This is possible with Git, and most anyone doing serious work with Rust should have Git installed anyway. But you can add that functionality to Cargo directly via the third-party Cargo subcommands cargo-clone and cargo-clone-crate.

Where can you find projects to tinker with and learn from? For starters, go to the Awesome Rust repository on GitHub. Some of the projects include:

• The Servo web browser engine, one of Rust’s first intended real-world applications.
• Microsoft’s Edit, a CLI-based editor with a modern UI.
• The mdBook project, for generating online books and e-books from Markdown documents.

Many other projects are useful on their own merit, not only for getting a leg up with Rust or because they’re components of a larger effort. These include Hickory DNS (a DNS server and client), Alacritty (a GPU-enhanced terminal emulator), and the MaidSafe decentralized data platform. (For fun, check out the Bevy game engine, which has many example projects.)

Awesome Rust also lists many of the best crates and third-party tools to learn about and put to use.

If you’re hunting for a project to get involved with as a developer, try searching GitHub for Rust-based projects that have open issues tagged with “good-first-issue.” That tag indicates an issue that will be relatively easy for a new developer to help out with. It’s a great way to learn the ropes with Rust while helping out a project.

When I was just starting out writing code, the market for developer tools was small. It mainly consisted of compilers, debuggers, and IDEs. The advent of visual development brought about the sale of component sets, but ultimately, the market wasn’t all that big and the marketing was straightforward.

But today? Today is a different story. The arrival of the Internet and SaaS has caused the developer tools market to explode. In addition, the software development world has become a lot more sophisticated. Deploying used to be as simple as “compile, slap it on a floppy disc, and ship it in a box.” No longer.

Because the market is so large, there is a lot of money sloshing around, and to attract that money, vendors need to attract the attention of developers. This, of course, means that every tool vendor employs a marketing department that strives to draw the eyes of developers to their wares.

There is only one problem here—developers refuse to be marketed to. Let’s take a look at why that is, and what they want from tool vendors instead. 

Spare me the marketing spiel

First, as a general rule, the users of development tools are not the people who hold the purse strings. Developers rarely control the tools budget; their managers do. Some development teams have their tools chosen for them from on high. Other more fortunate teams have their recommendations taken by management. But ultimately, the users of the tools don’t write the checks. 

Second, developers distrust and dismiss hype. If you want to get your developer product dismissed from the get-go, tell your potential customers that you are “excited and thrilled” to announce a launch.  Products that claim to “kill all the bugs in your software” will be set aside because, well, all software will always have bugs.

Developers are straightforward and respond to straightforward claims. They quickly swipe aside outlandish statements and flowery language that reeks of marketing-speak. They leave the “buzzword of the day” advertising to their managers.

Third, developers value peer recommendations over slick advertising. Upon hearing about a new tool, developers will usually go to Reddit or Hacker News looking for opinions rather than to the product’s website. This means that the traditional marketing campaign that you learned to do in your marketing classes in college are not effective. 

And the really fun part is that “astroturfing” a thread about your product on Hacker News or Reddit is just about impossible. If you go to the places where developers hang out and try to promote your product, you will be shot down faster than Mark Zuckerberg at a privacy conference.

Fourth, developers want hands-on proof rather than marketing pitches. They absolutely do not want to be sold to. No developer will even look twice at something labeled a “white paper.” And whatever you do, do not try to set up a sales call with a software developer. That is an utter fool’s errand. 

Just let me try the tool

Instead, developers want to do their own research, try things out, and read the documentation. Thus, a developer tools website should optimize for that by making it easy to find the things developers really want to see. 

You can work for weeks fine-tuning the words and messaging on your product website, but the developer eye will be drawn to the free tier of your application and the documentation. Make those things easy to access, and you’ll be ahead of the game. A “Developer” menu item with quick links to sandbox environments, working code demos showing your tool in action, and free APIs that we can tinker around with are what developers are really looking for.

Finally, make your pricing clear and prominent. Developers will definitely follow the “if you have to ask, you can’t afford it” principle and move on to a competitor if your site has a “call and set up an appointment with our sales team” schtick on the pricing page.

The real key to all of this is to provide the things developers want and to leave them alone to try out your tool. Don’t try to gather the typical marketing data, don’t try to get them to sign up for a webinar, and don’t try to get them on a phone call. Just let them play with your tool.

Hype, marketing-speak, and fluff will find no purchase in a developer’s brain. Create a marketing campaign that is simple, straightforward, and easy to access. Allow developers to try your product for themselves. Make your product sell itself. Sure, that’s a tricky proposition, but a developer tool that can’t sell itself will struggle in the marketplace.

The conversation around enterprise AI infrastructure has shifted dramatically in the past 18 months. While public cloud providers continue to dominate headlines with their latest GPU offerings and managed AI services, a quiet revolution is taking place in enterprise data centers: the rapid rise of Kubernetes-based private clouds as the foundation for secure, scalable AI deployments.

This isn’t about taking sides between public and private clouds—the decision was made years ago. Instead, it’s about recognizing that the unique demands of AI workloads, combined with persistent concerns around data sovereignty, compliance, and cost control, are driving enterprises to rethink their infrastructure strategies. The result? A new generation of AI-ready private clouds that can match public cloud capabilities while maintaining the control and flexibility that enterprises require.

Despite the push towards “cloud-first” strategies, the reality for most enterprises remains stubbornly hybrid. According to Gartner, 90% of organizations will adopt hybrid cloud approaches by 2027. The reasons are both practical and profound.

First, there’s the economics. While public cloud excels at handling variable workloads and providing instant scalability, the costs can spiral quickly for sustained, high-compute workloads—exactly the profile of most AI applications. Running large language models in the public cloud can be extremely expensive. For instance, AWS instances with H100 GPUs cost about $98,000 per month at full utilization, not including data transfer and storage costs.

Second, data gravity remains a powerful force. The cost and complexity of moving this data to the public cloud make it far more practical to bring compute to the data rather than the reverse. Why? The global datasphere will reach 175 zettabytes by 2025, with 75% of enterprise-generated data created and processed outside traditional centralized data centers.

Third, and most importantly, there are ongoing developments in regulatory and sovereignty matters. In industries such as financial services, healthcare, and government, regulations often mandate certain data never leave specific geographical boundaries or approved facilities. In 2024 the EU AI Act introduced comprehensive requirements for high-risk AI systems including documentation, bias mitigation, and human oversight. As AI systems increasingly process sensitive data, these requirements have become even more stringent.

Consider a major European bank implementing AI-powered fraud detection. EU regulations require that customer data remain within specific jurisdictions, audit trails must be maintained with millisecond precision, and the bank must be able to demonstrate complete control over data processing. While technically possible in a public cloud with the right configuration, the complexity and risk often make private cloud deployments more attractive.

Kubernetes: the de facto standard for hybrid cloud orchestration

The rise of Kubernetes as the orchestration layer for hybrid clouds wasn’t inevitable—it was earned through years of battle-tested deployments and continuous improvement. Today, 96% of organizations have adopted or are evaluating Kubernetes, with 54% specifically building AI and machine learning workloads on the platform. Kubernetes has evolved from a container orchestration tool to become the universal control plane for hybrid infrastructure.

What makes Kubernetes particularly well-suited for AI workloads in hybrid environments? Several technical capabilities stand out:

• Resource abstraction and scheduling: Kubernetes treats compute, memory, storage, and increasingly, GPUs, as abstract resources that can be scheduled and allocated dynamically. This abstraction layer means that AI workloads can be deployed consistently whether they’re running on-premises or in the public cloud.
• Declarative configuration management: The nature of Kubernetes means that entire AI pipelines—from data preprocessing to model serving—can be defined as code. This enables version control, reproducibility, and most importantly, portability across different environments.
• Multi-cluster federation: Modern Kubernetes deployments often span multiple clusters across different locations and cloud providers. Federation capabilities allow these clusters to be managed as a single logical unit, enabling workloads to move seamlessly based on data locality, cost, or compliance requirements.
• Extensibility through operators: The operator pattern has proven particularly valuable for AI workloads. Custom operators can manage complex AI frameworks, handle GPU scheduling, and even implement cost optimization strategies automatically.

The new demands of AI infrastructure

AI workloads present unique challenges that traditional enterprise applications don’t face. Understanding these challenges is crucial for architecting effective private cloud solutions, including:

• Compute intensity: Training a GPT-3 scale model (175B parameters) requires approximately 3,640 petaflop-days of compute. Unlike traditional applications that might spike during business hours, AI training workloads can consume maximum resources for days or weeks continuously. Inference workloads, while less intensive individually, often need to scale to thousands of concurrent requests with sub-second latency requirements.
• Storage performance: AI workloads are notoriously I/O intensive. Training data sets often span terabytes, and models need to read this data repeatedly during training epochs. Traditional enterprise storage simply wasn’t designed for this access pattern. Modern private clouds are increasingly adopting high-performance parallel file systems and NVMe-based storage to meet these demands.
• Memory and bandwidth: Large language models can require hundreds of gigabytes of memory just to load, before any actual processing begins. The bandwidth between compute and storage becomes a critical bottleneck. This is driving the adoption of technologies such as RDMA (Remote Direct Memory Access) and high-speed interconnects in private cloud deployments.
• Specialized hardware: While NVIDIA GPUs dominate the AI acceleration market, enterprises are increasingly experimenting with alternatives. Kubernetes’ device plugin framework provides a standardized way to manage diverse accelerators, whether they’re NVIDIA H100s, AMD MI300s, or custom ASICs.

One of the most significant shifts in AI development is the move toward containerized deployments. This isn’t just about following trends—it solves real problems that have plagued AI projects.

Consider a typical enterprise AI scenario: A data science team develops a model using specific versions of TensorFlow, CUDA libraries, and Python packages. Deploying this model to production typically requires the replication of the environment, which could often lead to inconsistencies between development and production settings.

Containers change this dynamic entirely. The entire AI stack, from low-level libraries to the model itself, gets packaged into an immutable container image. But the benefits go beyond reproducibility to include rapid experimentation, resource isolation, scalability, and the ability to bring your own model (BYOM).

Meeting governance challenges

Regulated industries clearly need AI-ready private clouds. These organizations face a unique challenge: they must innovate with AI to remain competitive while navigating a complex web of regulations that were often written before AI was a consideration.

Take healthcare as an example. A hospital system wanting to deploy AI for diagnostic imaging faces multiple regulatory hurdles. HIPAA compliance requires specific safeguards for protected health information, including encryption at rest and in transit. But it goes deeper. AI models used for diagnostic purposes may be classified as medical devices, requiring FDA validation and comprehensive audit trails.

Financial services face similar challenges. FINRA’s guidance makes clear that existing regulations apply fully to AI systems, covering everything from anti-money laundering compliance to model risk management. A Kubernetes-based private cloud provides the control and flexibility needed to meet these requirements through role-based access control (RBAC) to enforce fine-grained permissions, admission controllers to ensure workloads run only on compliant nodes, and service mesh technologies for end-to-end encryption and detailed audit trails.

Government agencies have become unexpected leaders in this space. The Department of Defense’s Platform One initiative demonstrates what’s possible, with multiple teams building applications on Kubernetes across weapon systems, space systems, and aircraft. As a result, software delivery times have been reduced from three to eight months to one week while maintaining continuous operations.

The evolution of the private clouds for AI/ML

The maturation of AI-ready private clouds isn’t happening in isolation. It’s the result of extensive collaboration between technology vendors, open-source communities, and enterprises themselves.

Red Hat’s work on OpenShift has been instrumental in making Kubernetes enterprise-ready. Their OpenShift AI platform integrates more than 20 open-source AI and machine learning projects, providing end-to-end MLOps capabilities through familiar tools such as JupyterLab notebooks. Dell Technologies has focused on the hardware side, creating validated designs that combine compute, storage, and networking optimized for AI workloads. Their PowerEdge XE9680 servers have demonstrated the ability to train Llama 2 models when combined with NVIDIA H100 GPUs.

Yellowbrick also fits into this ecosystem by delivering high-performance data warehouse capabilities that integrate seamlessly with Kubernetes environments. For AI workloads that require real-time access to massive data sets, this integration eliminates the traditional ETL (extract, transform, load) bottlenecks that have plagued enterprise AI projects.

NVIDIA’s contributions extend beyond just GPUs. Their NVIDIA GPU Cloud catalog provides pre-built, optimized containers for every major AI framework. The NVIDIA GPU Operator for Kubernetes automates the management of GPU nodes, making it dramatically easier to build GPU-accelerated private clouds.

This ecosystem collaboration is crucial because no single vendor can provide all the pieces needed for a successful AI infrastructure. Enterprises benefit from best-of-breed solutions that work together seamlessly.

Looking ahead: the convergence of data and AI

As we look toward the future, the line between data infrastructure and AI infrastructure continues to blur. Modern AI applications don’t just need compute—they need instant access to fresh data, the ability to process streaming inputs, and sophisticated data governance capabilities. This convergence is driving three key trends:

• Unified data and AI platforms: Rather than separate systems for data warehousing and AI, new architecture provides both capabilities in a single, Kubernetes-managed environment. This eliminates the need to move data between systems, reducing both latency and cost.
• Edge AI integration: As AI moves to the edge, Kubernetes provides a consistent management plane from the data center to remote locations.
• Automated MLOps: The combination of Kubernetes operators and AI-specific tools is enabling fully automated machine learning operations, from data preparation through model deployment and monitoring.

Practical considerations for implementation

For organizations to consider this path, several practical considerations emerge from real-world deployments:

• Start with a clear use case: The most successful private cloud AI deployments begin with a specific, high-value use case. Whether it is fraud detection, predictive maintenance, or customer service automation, having a clear goal helps guide infrastructure decisions.
• Plan for data governance early: Data governance isn’t something you bolt on later. With regulations such as the EU AI Act requiring comprehensive documentation of AI systems, building governance into your infrastructure from day one is essential.
• Invest in skills: Kubernetes and AI both have steep learning curves. Organizations that invest in training their teams, or partner with experienced vendors, see faster time to value.
• Think hybrid from the start: Even if you’re building a private cloud, plan for hybrid scenarios. You might need public clouds for burst capacity, disaster recovery, or accessing specialized services.

The rise of AI-ready private clouds represents a fundamental shift in how enterprises approach infrastructure. The objective is not to dismiss public cloud solutions, but to establish a robust foundation that offers flexibility to deploy workloads in the most suitable environments.

Kubernetes has emerged as the critical enabler of this shift, providing a consistent, portable platform that spans public and private infrastructure. Combined with a mature ecosystem of tools and technologies, Kubernetes makes it possible to build private clouds that match or exceed public cloud capabilities for AI workloads.

For enterprises navigating the complexities of AI adoption, balancing innovation with regulation, performance with cost, and flexibility with control, Kubernetes-based private clouds offer a compelling path forward. They provide the control and customization that enterprises require while maintaining the agility and scalability that AI demands.

The organizations that recognize this shift and invest in building robust, AI-ready private cloud infrastructure today will be best positioned to capitalize on the AI revolution while maintaining the security, compliance, and cost control their stakeholders demand. The future of enterprise AI isn’t in the public cloud or the private cloud—it’s in the intelligent orchestration across both.

When I was a young engineer, there was a gruff old programmer named Larry who often imparted his wisdom to us young’uns. A man in his forties, he had that gritty, seen-it-all manner that bespoke years of hard-fought battles in the coding trenches. His was a heart of gold covered in a cloak of cynicism; imagine Philip Seymour Hoffman as a Perl programmer.

Over his fourteenth cup of coffee, Larry would dispense his ruminations on the life of coding, the realities of projects (and project managers), and the virtues of vi versus EMACS. One thing he said, that has stuck with me all these years, was that fourth-generation languages (4GL) had never worked and never would.

Like most software developers, I have been frolicking in the gardens of AI-generated code for a couple of years now. I’m starting to wonder: Is this it? Have we arrived at the long-awaited utopia of 4GL?

What is 4GL?

Wikipedia has a good overview of the fourth-generation language concept, which was supposed to sweep across software like a revelation. Among other things, 4GLs are sometimes described as “program-generating languages.” They are a higher-level abstraction from familiar third-generation languages like Java and JavaScript, and tend to focus on more natural language syntax.

Terms like natural language interface and program-generating certainly do sound like generative AI, don’t they? There was even a book written in 1981 called Application Development Without Programmers, which foresaw a future where artificial intelligence would replace human developers.

But actual 4GLs like FOCUS, along with modern derivatives like WYSIWYG editors, rapid application development (RAD) frameworks, and low-code/no-code platforms, all fail to live up to that promise for one simple reason: They all require a developer who knows how to use them. Even with natural language coding solutions, there are times when someone needs to be able to drop into the underlying system and fix it. (See my recent Roo Code review for more about this.)

4GL and generative AI

Most non-programmers would agree that using a 4GL-derived solution feels a lot like programming. Even a WYSIWYG RAD framework requires considerable thought and some knowledge of programming concepts. You need a basic understanding of datastores and schemas (yes, even with NoSQL), the middleware that connects a datastore to the interface, and the interface itself. You also need to understand the relationship between services and APIs and the infrastructure that enables and secures them.

This also seems to be true when using large language models (LLMs) to generate code, but to a lesser degree. Very broad natural language descriptions of functionality are not terribly effective. What is most effective when programming with AI, in my experience, is an iterative back-and-forth process that dips in and out of varying degrees of granularity.

The more we push abstractions to handle complexity, the more evident it becomes that a proficient human being must still drive the work itself. Understanding the details that are smoothed out by abstraction become more important when each of the parts and all their interrelations are stretched.

When working directly on the details of a component, using a 4GL tool to interface with it can feel like trying to do detailed handiwork with bulky gloves on. I think most experienced programmers would say the same about using an AI coding assistant.

What AI gets right

Don’t get me wrong: It’s incredibly handy to be able to ask an AI tool to spit out a decent function that does exactly what you need, and a recent study shows that more senior developers are taking full advantage of AI capabilities. But the more broadly we shotgun AI power at complex problems, the more we create something that feels like technical debt. Maybe a better term in this case would be comprehension debt.

AI is a great tool for interfacing with general knowledge about design and architecture. The ability to bring programming code and concepts into a common frame is a big advantage of AI, and of 4GL. But to leverage either tool, the user must have some basic understanding of programming concepts and how they are applied.

Without the will to completion

Higher order abstractions tend to excel at prototyping, but they’re not so well-suited to developing the final product in production. That last act tends to require one or more people who not only understand the underlying infrastructure but have what I call the will to completion.

What I’m saying is, you need someone who will take whatever mechanism is provided and drive toward an envisioned goal, and who will keep adapting and moving forward until that goal is realized. This is a uniquely human trait that cannot be abstracted away. Like 4GL, artificial intelligence may serve that end, but it can’t drive it.

A human programmer brings something to the table which I will call caring, also known as “giving a @#^$.” Every experienced developer by now has noticed the way that AI will just confidently deliver the wrong solution over and over again, or break one thing while fixing another. That’s because AI doesn’t actually care about the result.

When laziness leads to more work

It’s a strange paradox that the more you need the AI, the less useful it is. Seasoned software developers can confidently use AI because, when it goes wrong, we can just jump in there and fix it. Years of programming experience make it easy to see where machine intelligence is going off the rails. But when less experienced developers rely on AI, they are less equipped to catch the mistakes. This is the peril of “lazy programming” writ large.

As an example, consider my long-standing dysfunctional relationship with CSS. The truth is, I’m just not very good at it. For a time, I was thinking AI coding assistance might solve my problem. With AI, I might suddenly become a more competent, less-stressed-out CSS developer. Instead, I am still a mediocre CSS developer—and now also a user of AI-generated CSS.

I can keep muddling through with CSS and leaning on AI tools to catch me when I fail. But the real solution, I’ve found, is to work with a human being who actually understands CSS in all the ways I don’t. That’s okay; I like those people and enjoy working with them. They are magical beings, kind of like those who can cook pasta properly.

Conclusion

The dream of AI looks an awful lot like the dream of 4GL. Clearly, AI has achieved more significance in its practical effects than 4GLs ever did. But the limitations and fault lines are similar enough to merit our attention. I seriously wonder if the vast tracts of AI-generated code will just drive up the demand for more software engineering expertise—old hands like Larry, who remain skeptical any of this will lead to much.

Microsoft has released its first preview of the Visual Studio 2026 IDE through the company’s new Insiders channel, which replaces the old Preview channel for early access to upcoming features. The new IDE offers deeper integration of the GitHub Copilot AI coding assistant, including a profiler agent that analyzes performance and suggests fixes.

Visual Studio 2026 Insiders, announced September 9, can be downloaded at visualstudio.microsoft.com/insiders/. In addition to AI “woven directly into the developer workflow,” Visual Studio 2026 features snappier performance and a modern design that makes the environment feel lighter and more focused, according to Microsoft.

Working alongside GitHub Copilot, the Profiler Agent in Visual Studio 2026 helps developers understand and fix performance issues without needing to be a profiling expert, according to release notes. The Profiler Agent can analyze CPU usage, memory allocations, and runtime behavior, along with surfacing performance bottlenecks, and suggest optimizations. Further, developers now can bring their own language models to Visual Studio Chat, while improved code search capabilities in Copilot Chat promise to give developers more relevant results.

Also featured in Visual Studio 2026 is a cleaner and more modern interface that is consistent with the Fluent UI design system, providing a workspace that feels calm and intentional, Microsoft said. New color themes make the environment more comfortable for long sessions and more accessible by default. An adaptive paste capability saves time and reduces effort by automatically adjusting pasted code to fit the context of existing code, minimizing the need for manual modifications, Microsoft said.

Visual Studio 2026 installs side-by-side with earlier versions. Developers using Visual Studio 2022 can import components and settings to start coding immediately.

Other improvements in Visual Studio 2026 Insiders include:

• The debugger now displays inline post-return values, showing actual return values of functions where they are used.
• A Quick Find feature lets users search within string values in the Text Visualizer.
• Comments now render via Markdown formatting, thus making it easier to read and format feedback.
• Code coverage is now included in the Community and Professional editions.

Java Development Kit (JDK) 25, a new Long-Term Support (LTS) release of standard Java, is now generally available. The release brings 18 features, five of which Oracle touts as assisting with AI development.

JDK 25 comes on the heels of JDK 24, a six-month-support release that arrived March 18. As a Long-Term support release, JDK 25 will get at least eight years of Premier commercial support from Oracle. The most recent LTS release was JDK 21, which arrived in September 2023.

JDK 25 can be downloaded from jdk.java.net. The features in the release include an enhancement to the JDK Flight Recorder (JFR) to capture CPU-time profiling information on Linux, PEM (Privacy-Enhanced Mail) encodings of cryptographic objects, the Shenandoah garbage collector, ahead-of-time command-line ergonomics, ahead-of-time method profiling, JDK Flight Recorder (JFR) cooperative sampling, JFR method timing and tracing, compact object headers, and a third preview of primitive types in patterns, instanceof, and switch. Other features include scoped values, a vector API, a key derivation function API, structured concurrency, flexible constructor bodies, module import declarations, compact source files and instance main methods, a stable values API, and removal of the 32-bit x86 port.

Five of these features aid in the development of AI applications, Oracle said. Primitive types in patterns, instanceof, and switch make integrating business logic with primitive types from AI easier, according to the company. Module import declarations offer easier integration of business logic with AI inference, libraries, or service calls, while the Vector API often is used in AI inference and compute scenarios. Structured concurrency fits in with AI because AI development often involves running multiple tasks in parallel. And scoped values enable sharing of immutable data within and across threads with lower space and time costs versus thread-local variables, Oracle said.

JFR CPU-time profiling enhances the JDK Flight Recorder to capture more accurate CPU-time profiling information on Linux. The JFR is the JDK’s profiling and monitoring facility. Enhancing the JFR to use the Linux kernel’s CPU timer to safely produce CPU-time profiles of Java programs would help developers optimize the efficiency of the Java applications they deploy on Linux. CPU-time profiling on the JFR may be added for other platforms in the future. The CPU time-profiling feature is the third feature involving the JFR in JDK 25, with the others being the cooperative sampling and method timing and tracing capabilities. This is an experimental feature.

With PEM encodings of cryptographic objects, JDK 25 previews a concise API for encoding objects that represent cryptographic keys, certificates, and certificate revocation into the widely used PEM format transport, and for decoding from the format back into objects. The Java platform has not had an easy-to-use API for decoding and encoding in the PEM format. A main goal of the feature is ease of use. Another goal is support for conversions between PEM text and cryptographic objects that have standard representations in the binary formats PKCS#8 (for private keys), X.509 (for public keys, certificates, and certificate revocation lists), and PKCS#8 v2.0 (for encrypted private keys and asymmetric keys).

Generational Shenandoah changes the generational mode of the Shenandoah garbage collector (GC) from an experimental feature to a product feature. Previewed in JDK 24, the GC has had many stability and performance enhancements, according to the proposal. The GC in JDK 24 was intended to offer collection capabilities to improve sustainable throughput, load-spike resilience, and memory utilization Several users have reported running demanding workloads with this GC. Generational Shenandoah once was planned for JDK 21 in 2023 but was dropped because the capability was deemed not ready at the time.

Ahead-of-time command-line ergonomics is intended to make it easier to create ahead-of-time (AOT) caches, which accelerate the startup of Java applications by simplifying commands needed for common use cases. Goals include simplifying the process of creating an AOT cache with no loss of expressiveness, and not introducing fundamentally new AOT workflows but making it easier to access existing ones. This proposal follows the ahead-of-time caches introduced by ahead-of-time class loading and linking in JDK 24.

Ahead-of-time method profiling would improve warmup time by making method execution profiles from a previous run of an application available right away when the HotSpot JVM starts. This will enable the just-in-time (JIT) compiler to generate native code instantly upon application startup rather than having to wait for the collection of profiles. Here, goals include helping applications warm up quicker; not requiring any changes to the code of applications, libraries, or frameworks; and not introducing any new constraints on application execution. The proposal also would not introduce new AOT workflows, but would use existing AOT cache creation commands. The AOT cache introduced in JDK 24 would be extended to collect method profiles during training runs.

JFR cooperative sampling would improve the stability of the JDK Flight Recorder when it asynchronously samples Java thread stacks. This would be achieved by walking call stacks only at safepoints while minimizing safepoint bias.

JFR method timing and tracing would extend the JDK Flight Recorder with facilities for method timing and tracing rather than via bytecode instrumentation. Goals of this feature include allowing execution times and stack traces to be recorded for specific methods without needing source code modifications, and recording exact statistics for method invocations. Another goal is allowing methods to be selected via command-line argument, configuration files, the jcmd tool, and over the network via the Java Management Extensions API. Timing and tracing method invocations can help identify performance bottlenecks, optimize code, and find the root cause of bugs.

Compact object headers, an experimental feature in JDK 24, would become a product feature in JDK 25. In JDK 24, this capability was introduced to reduce the size of object headers in the HotSpot JVM from between 96 bits and 128 bits down to 64 bits on 64-bit architectures. This reduces the heap size, improves deployment density, and increases data locality. Since JDK 24, compact object headers have proven their stability and performance, the proposal says.

A third preview of primitive types in patterns, instanceof, and switch would enhance pattern matching by allowing primitive types in all pattern contexts and extend instanceof and switch to work with all primitive types. The intent is to help developers increase Java programming productivity by making Java more uniform and expressive. Originally proposed in JDK 23 and followed up in JDK 24, this would still be a preview language feature in JDK 25. Among goals are enabling data exploration by allowing type patterns for all types, whether primitive or reference, and providing easy-to-use constructs that eliminate the risk of losing information due to unsafe casts.

Scoped values, to be previewed for a fifth time, allows a method to share immutable data with its callees within a thread and with child threads. Scoped values are easier to reason about than thread-local variables, according to the OpenJDK JDK Enhancement Proposal (JEP). They also have lower space and time costs, especially when used together with virtual threads and structured concurrency. Goals of the plan include ease of use, comprehensibility, robustness, and performance. The scoped values API was proposed for incubation in JDK 20, proposed for preview in JDK 21, and subsequently refined for JDK 22 through JDK 24. The feature will be finalized in JDK 25, with one change: the ScopedValue.orElse method no longer accepts null as its argument.

The vector API is designed to express vector computations that reliably compile at runtime to optimal vector instructions on supported CPUs, thus achieving performance superior to equivalent scalar computations. The API will be incubated for the 10th time in JDK 25, after having been incubated in every release dating back to JDK 16. Two notable implementation changes are featured in the JDK 25 implementation of the API. First, the implementation now links to native mathematical-function libraries via the Foreign Function and Memory API rather than custom C++ code inside the HotSpot JVM, thus improving maintainability. Second, addition, subtraction, division, multiplication, square root, and fused multiply/add operations on Float16 values now are auto-vectorized on supporting x64 CPUs. Additionally, VectorShuffle now supports access to and from MemorySegment.

The key derivation function API provides for functions that are cryptographic algorithms for deriving additional keys from a secret key and other data. This feature is geared to helping developers prepare for emerging quantum computing environments. One of the goals of the API is enabling applications to use key derivation function algorithms such as the HMAC-based Extract-and-Expand Key Derivation Function and Argon2. Other goals include allowing security providers to implement key derivation function algorithms in either Java code or native code, and enabling the use of key derivation functions in key encapsulation mechanism implementations such as ML-KEM, in higher level protocols such as Hybrid Key Exchange in TLS 1.3, and in cryptographic schemes such as Hybrid Public Key Encryption. The API will be finalized in JDK 25 after being previewed in JDK 24.

Structured concurrency was previewed previously in JDK 21 through JDK 24, after being incubated in JDK 19 and JDK 20. Now in its fifth preview, structured concurrency treats groups of related tasks running in different threads as single units of work. This streamlines error handling and cancellation, improves reliability, and enhances observability, the proposal states. The primary goal is to promote a style of concurrent programming that can eliminate common risks arising from cancellation and shutdown, such as thread leaks and cancellation delays. A second goal is to improve the observability of concurrent code. JDK 25 introduces several API changes. In particular, a StructuredTaskScope is now opened via static factory methods rather than public constructors. Also, the zero-parameter open factory method covers the common case by creating a StructuredTaskScope that waits for all subtasks to succeed or any subtask to fail.

Flexible constructor bodies was previewed in JDK 22 as “statements before super(…)” as well as in JDK 23 and JDK 24. The feature is intended to be finalized in JDK 25. In flexible constructor bodies, the body of a constructor allows statements to appear before an explicit constructor invocation such as super (…) or this (…). These statements cannot reference the object under construction but they can initialize its fields and perform other safe computations. This change lets many constructors be expressed more naturally and allows fields to be initialized before becoming visible to other code in the class, such as methods called from a superclass constructor, thereby improving safety. Goals of the feature include removing unnecessary restrictions on code in constructors; providing additional guarantees that state of a new object is fully initialized before any code can use it; and reimagining the process of how constructors interact with each other to create a fully initialized object.

Module import declarations, which was previewed in JDK 23 and JDK 24, enhances the Java language with the ability to succinctly import all of the packages exported by a module. This simplifies the reuse of modular libraries but does not require the importing code to be in a module itself. Goals include simplifying the reuse of modular libraries by letting entire modules be imported at once; avoiding the noise of multiple type import-on-demand declarations when using diverse parts of the API exported by a module; allowing beginners to more easily use third-party libraries and fundamental Java classes without having to learn where they are located in a package hierarchy; and ensuring that module import declarations work smoothly alongside existing import declarations. Developers who use the module import feature should not be required to modularize their own code.

Compact source files and instance main methods evolves the Java language so beginners can write their first programs without needing to understand language features designed for large programs. Beginners can write streamlined declarations for single-class programs and seamlessly expand programs to use more advanced features as their skills grow. Likewise, experienced developers can write small programs succinctly without the need for constructs intended for programming in the large, the proposal states. This feature, due to be finalized in JDK 25, was previewed in JDK 21, JDK 22, JDK 23, and JDK 24, albeit under slightly different names. In JDK 24 it was called “simple source files and instance main methods.”

Stable values are objects that hold immutable data. Because stable values are treated as constants by the JVM, they enable the same performance optimizations that are enabled by declaring a field final. But compared to final fields, stable values offer greater flexibility regarding the timing of their initialization. A chief goal of this feature, which is in a preview stage, is improving the startup of Java applications by breaking up the monolithic initialization of application state. Other goals include enabling user code to safely enjoy constant-folding optimizations previously available only to JDK code; guaranteeing that stable values are initialized at most once, even in multi-threaded programs; and decoupling the creation of stable values from their initialization, without significant performance penalties.

Removal of the 32-bit x86 port involves removing both the source code and build support for this port, which was deprecated for removal in JDK 24. The cost of maintaining this port outweighs the benefits, the proposal states. Keeping parity with new features, such as the foreign function and memory API, is a major opportunity cost. Removing the 32-bit x86 port will allow OpenJDK developers to accelerate the development of new features and enhancements.

Separate from the official feature list, JDK 25 also promises to bring performance improvements to the class String, by allowing the String::hashCode function to take advantage of a compiler optimization called constant folding. Developers who use strings as keys in a static unmodifiable Map should see significant performance boosts, according to a May 1 article on Oracle’s Inside Java website.

MongoDB has launched a new AI-driven application modernization platform called AMP, designed to help enterprises transform legacy applications into modern, scalable services that support AI and automation.

Legacy applications often accumulate technical debt, such as outdated code, architecture, and dependencies, which are costly to maintain and hinder integration of AI or agentic systems, according to Shilpa Kolhar, SVP of product and engineering at MongoDB.

The hindrance to moving to automated systems could mean that enterprises start falling behind their competition, Kolhar said, adding that the company’s modernization platform tries to bypass this challenge for enterprises.

Components of the platform

The new platform will offer a dedicated team of engineers, spread globally, who will oversee and guide enterprises through the entire transformation process, including deployment.

A typical modernization journey for an enterprise at MongoDB, according to Kolhar, will include a consulting process that will include discussions on expected pricing, and after that, the AI-driven platform will be used to conduct tests for existing applications, creating a baseline that captures how legacy systems behave in production.

“This upfront investment in testing becomes the foundation for everything that follows, providing guardrails that ensure modernized code performs identically to the original while giving teams the confidence to make changes without fear of breaking critical business processes,” Kolhar said.

The entire process will get completed through a testing-transformation-trial-deployment loop, Kolhar added.

Devin Dickerson, principal analyst at Forrester, termed this hybrid approach of using an AI-assisted platform along with engineers is “holistic.”

“Most of the AI-assisted developer tooling in the marketplace today works best for net-new applications,” Dickerson said.

MongoDB’s AMP offers the best of both worlds by combining human engineers with AI, as some vendors offer automated tooling and no human layer, while others offer only a human-layer but not AI-driven tooling, said Rachel Stephens, research director at RedMonk.

“Enterprise modernization has traditionally relied on system integrators (SIs) or other outside consultants. These projects tend to be highly manual, making them slow and expensive. It’s not uncommon for these engagements to stall before delivering real results,” Stephens explained, adding that MongoDB’s AMP lowers the risk of modernization while maintaining the desired pace.

Differentiated from rivals

MongoDB, according to analysts, stands out from rivals due to its positioning of the data layer at the core of its offerings.

“MongoDB’s data-layer-out transformation approach makes sense for many legacy applications where the data layer will present the biggest challenge to the overall modernization,” Dickerson said.

The analyst also pointed out that some of the rivals offer tools that are known to drive vendor lock-in, and enterprises that want a cloud platform agnostic approach may find MongoDB’s approach suitable for their needs.

MongoDB claims that its customers, including Bendigo Bank and Lombard Odier, have seen gains up to 10x on tasks like code transformation on the use of the platform.

The platform is expected to start picking up even more pace once it completes more modernizations, MongoDB said. The NoSQL document database provider has not clarified the list of legacy code and databases it currently supports for modernization, but Kolhar said that the company plans to “mindfully and gradually” expand the types of legacy code it can modernize.

Microsoft is adding two new features to its cloud-based Fabric to help agentic applications make more accurate decisions while navigating complex workflows and help developers integrate AI-driven insights directly into an enterprise’s data operations.

The two new features — Graph and Maps — are being integrated into Fabric’s Real-Time Intelligence workload.

Fabric, released in May 2023, brings together six “workloads”: Data Factory, Data Engineering, Data Warehouse, Data Science, Real-Time Intelligence, and Power BI, which are designed to help enterprises reduce IT integration overhead, complexity, and cost.

The Real-Time Intelligence workload, specifically, was built to help enterprises make better decisions by generating insights from real-time data. It combines mainly two modules — Synapse Real-Time Analytics and Data Activator, along with other functions.

Built on LinkedIn’s graph technology

The Graph feature has been taken from LinkedIn’s graph database technology that supports visual exploration as well as natural language querying, according to Arun Ulagaratchagan, corporate vice president of Azure Data at Microsoft.

Explaining the rationale behind the usage of LinkedIn’s graph technology, Ulagaratchagan said that Microsoft itself did not have a mature, full-scale graph database to build on.

That gap, he added, was bridged when a LinkedIn engineering team specializing in graph technology was moved under his leadership “a while back”, giving Fabric a direct line to the social network’s “proven expertise” in modelling complex relationships at scale.

Moor Insights and Strategy’s principal analyst Robert Kramer backed Microsoft’s strategy to reuse LinkedIn’s graph foundation as it reduces risk, speeds up adoption, and shows Microsoft isn’t starting from scratch with a new engine, boosting customer confidence.

For enterprises, the new graph feature can help agents or agentic applications by improving query performance, data interpretation, and enabling visual exploration of data, analysts said.

These benefits, according to Kramer, can be achieved as a graph can help AI agents understand relationships between data points like suppliers, customers, and operational touchpoints, instead of seeing and reading data as separate tables.

Maps, just like Graph, can be used to add geospatial context to agents and agentic applications, Microsoft said, adding that it also can be used to transform volumes of location-based data into interactive, real-time visualizations that drive location-aware decisions.

Supply chain and logistics, Retail, and healthcare, as industry sectors, probably stand to gain the most from Maps and Graph, Kramer said, adding that while Maps can help track shipments, service areas, and demographics, Graph can model supplier dependencies and patient-provider relationships.

Both Maps and Graph are currently in public preview.

Developer-focused MCP for Fabric to connect agents

In order to enable developers to connect agentic applications to interact with Fabric’s ecosystem, Microsoft is introducing a MCP Server for Fabric, named Fabric MCP.

Fabric MCP, which is open source and can be integrated with VS Code and GitHub Codespaces, can be used to enable agents to build Fabric items, such as pipelines and notebooks, via natural language prompts, Ulagaratchagan said.

It can also be used to generate code based on context-aware prompts, he added.

Moor Insights and Strategy’s Kramer sees the launch of the MCP Server as an important step.

“It gives developers a consistent way to interact with Fabric’s APIs while layering in AI-assisted development. In practice, it makes it easier to go from raw data pipelines to ready-to-run applications,” Kramer said.

Seconding Kramer, Constellation Research principal analyst Michael Ni said that with Fabric MCP, developers no longer have to connect to APIs one at a time for each service, accelerating development.

Further, Kramer pointed out that the integration with VS Code will help developers get work done faster as it meets developers where they already work.

“With MCP integrated, developers can build, test, and deploy Fabric-based solutions in tools they’re already familiar with, without having to switch contexts,” Kramer explained.

Microsoft isn’t the only data analytics software provider that is running into MCP. Rivals, such as Snowflake, Databricks, and Teradata, are also offering MCP-based options.

However, Constellation Research’s Ni cautioned that just having an MCP Server isn’t the win.
“The win depends on what you layer on top. Microsoft is smart to combine MCP with Fabric’s Graph and Maps, plus VS Code integration. That makes it not just another server, but a part of the Microsoft platform for agentic decisioning and automation,” Ni said.

Fabric MCP is currently in preview.

The three biggest hyperscalers in the US are AWS, Microsoft Azure, and Google Cloud. The biggest hyperscaler in China (and the sixth in the world) is Alibaba Cloud. Alibaba’s large language model and multimodal model family, Tongyi Qianwen, or Qwen, competes with models from the US hyperscalers as well as models from OpenAI and Anthropic, but Qwen is free.

One of the few drawbacks of Qwen models is that they won’t answer any questions about historical people or events that embarrass the mainland Chinese government. They won’t even tell you about the government of Taiwan. For the purposes of code generation, however, Qwen’s political conditioning doesn’t matter, at least not to me. If that matters to you, don’t use Qwen.

In this review, we’ll examine Qwen Code, a CLI client; Qwen3-Coder, a large language model trained for code generation; and other Qwen models and interfaces.

Qwen Code is a fork of Gemini CLI. It’s so light an adaptation that the entire documentation section of the repository still says Gemini. Since the fork, Gemini CLI has gotten an add-on that makes it integrate nicely with VS Code; Qwen Code currently lacks that.

Alibaba considers the Qwen3-Coder model to be its “most agentic code model to date,” and says that it is comparable to Claude Sonnet 4 based on its SWE-Bench Verified benchmark score. More specifically, Qwen3-Coder-480B-A35B-Instruct is a 480-billion-parameter mixture-of-experts model with 35 billion active parameters that supports a context length of 256K tokens natively and 1M tokens with extrapolation methods.

Qwen3-Coder was pretrained on 7.5T tokens (70% code ratio), to “excel in coding while preserving general and math abilities,” and then improved with long-horizon reinforcement learning using real-world multi-turn coding tasks.

A small Qwen3-Coder model (30 billion parameters, 19GB) is available in Ollama for local use. The full 480B parameter model is also available in Ollama, if you have a GPU with enough memory to run it. The full Qwen3-Coder model can be run via Qwen Chat, Qwen Code, Alibaba Cloud Model Studio, Claude Code, and Cline.

Several other Qwen3 models are currently available in Qwen Chat: Qwen3-235B-A22B-2507, Qwen3-30B-A3B-2507, and Qwen3-Coder-Flash, plus many previous-generation models. It’s easy to confuse these. Qwen3-Coder is supposed to be the big gun for code generation, software development, and the like, although I initially (out of confusion) tried Qwen3-235B-A22B-2507 for code generation and thought it was pretty good, as the mistakes it made were quickly corrected.

Foundry

Qwen Code

Qwen Code is a command-line interface to the Qwen3-Coder API; it currently picks up the Qwen3-Coder-Plus model. Qwen Code is specifically optimized for Qwen3-Coder models. It enhances your development workflow with advanced code understanding, automated tasks, and intelligent assistance.

Qwen Code supports the agent and tool use aspects of Qwen3-Coder. That means that in addition to generating code, it can compile, run, and debug the code at the command line. It might be able to use Model Context Protocol (MCP) servers; I haven’t tried to set any up.

As I mentioned earlier, the developers forked Gemini CLI to bootstrap the development of the app. This is perfectly legitimate, since Gemini CLI is open source with an Apache-2.0 license, but seeing the old Gemini CLI code and name in unmodified parts of the qwen-code repository made me laugh. (That has since been fixed, at least on the surface.)

When Qwen Code first shipped, its authentication was broken for international users. There was a lot of feedback in the issues section of the repository from users outside of China, and some misunderstanding from the Chinese maintainers, but eventually they added a Qwen OAuth option that works well and is free, with the same generous quotas as the OpenAI-compatible Chinese authentication.

Qwen Chat

Qwen Chat is a free web AI assistant powered by Qwen series models, including Qwen3-Coder, Qwen3-235B-A22B-2507, Qwen3-30B-A3B-2507, and Qwen3-Coder-Flash, as well as many previous-generation models. Qwen Chat offers options for deep thinking, web search, document upload, media upload, and voice input for models that support them. In addition to generating code and text, explaining code, and summarizing documents, Qwen Chat can edit, analyze, and generate images, and generate video.

If you use Qwen Chat for code generation, you can download the file or copy the code (to, for example, your code editor) and then run it yourself, or ask Qwen to run it. While Qwen Chat doesn’t interact with the command line, it can interpret some programming languages, including Python. If you need an environment that interacts with the command line, use Qwen Code.

The Qwen Chat app for macOS and Windows has explicit configuration of MCP servers, with one-button enabling of seven MCP servers (at the moment), limited to five active simultaneously. The Qwen Chat website does not have explicit configuration of MCP servers. There is a Qwen Chat app for Android, but it only installs in mainland China, unless you download the APK and bypass advanced protection to allow the installation. The Qwen Chat app for iOS is strictly limited to China. (I haven’t tried using a VPN to spoof my location; that might work if you can find a VPN server in China. For example, ExpressVPN has two servers in Hong Kong that are supposed to work reliably to access Chinese sites.)

Qwen3-Coder

I mentioned earlier that Alibaba says that Qwen3-Coder is comparable to Claude Sonnet 4 based on its SWE-Bench Verified benchmark score. While benchmarks have their uses, they don’t always reflect real life.

My own tests give me the impression that Claude Sonnet 4 is more capable and reliable than Qwen3-Coder for most coding use cases, and that Claude Opus 4.1 is even better. Qwen3-Coder feels closer to Gemini 2.5 Pro, although without the latter’s close integration with Google Cloud capabilities.

On the other hand, Qwen3-Coder and Gemini 2.5 Pro are free. Neither Claude Sonnet 4 nor Claude Opus 4.1 is free, except for light usage of Sonnet.

A few Qwen3 experiments

One of my easier standard programming tests is to ask a generative AI to generate a Python program that summarizes the InfoWorld.com home page. Qwen3-Coder nailed this on the first try. A year or two ago this task gave many models trouble; these days it’s table stakes.

I’ve learned not to ask a model to “scrape” a website, since that implies stealing content, and will trigger some models to lecture me on ethics. (As if.) Of course, that’s how a lot of LLMs get their training materials, but let’s not quibble.

Foundry

Foundry

In addition to code generation, Qwen-Coder can explain code, including whole repositories. If you supply the URL to a web repository, for example on GitHub, Qwen Code will use its WebFetch tool to grab content from the repo.

Here I made it simpler, by updating my local copy of the https://github.com/cline/cline repo and changing to that directory.

That isn’t a bad summary, at all.

Next I asked for something a little harder, but not out of reach for the best models: high-precision calculation of π in C++. There are three big pieces to this: finding a good algorithm, picking a good multiple-precision floating-point library, and implementing the algorithm correctly.

│  > generate a C++ program to calculate pi to the number of decimal places specified in 
│    the command line, which may be a very large number. Use the best possible algorithm. 
│    save the code in the qwen directory with the name pi_value.                                                                             


✦ I'll create a C++ program to calculate pi to a specified number of decimal places using the Chudnovsky algorithm, which is one of the fastest known algorithms for computing pi.

  First, let me check if the qwen directory exists and create the program file.

 
 │ ✔  ReadFolder qwen     
 │                       
 │    Listed 8 item(s).  
 
✦ I see there's already a qwen directory with some pi calculation programs. I'll create a new program using the Chudnovsky algorithm which is one of the most efficient methods for computing pi to many decimal places.

So far, so good. The Chudnovsky algorithm is currently the fastest-converging way of calculating π, although it’s not exactly compact as far as the code goes.

Up until this point, Qwen-Code was more or less on task. The code isn’t perfect, but it is at least an attempt to implement the Chudnovsky algorithm. Here it starts going off the rails. Machin’s formula isn’t nearly as efficient as the Chudnovsky algorithm.

Huh? What a lame excuse not to use the Chudnovsky algorithm. Honestly, I’ve seen this bait and switch code before, on Stack Overflow if I remember correctly. I suspect that Qwen-Code is just regurgitating somebody’s bad answer from SO.   

✦ Now I'll compile the program to make sure it works correctly. First, let me check if we have the required libraries installed.

 
 │ ✔  Shell which g++ (Check if g++ compiler is available) 
 │                                             
 │    /usr/bin/g++                            
 │                            
 
✦ Let's check if we have the required GMP and MPFR libraries installed.

 
 │ ✔  Shell brew list | grep mpfr (Check if MPFR library is installed via Homebrew) 
 │                                    
 │    mpfr                          
 │                              
 
✦ Good, we have the MPFR library installed. Let's also check for GMP:

 
 │ ✔  Shell brew list | grep gmp (Check if GMP library is installed via Homebrew)
 │                                               
 │    gmp           
 │                
 
 
 │ x  Shell {"command":"g++ -o pi_value pi_value.cpp -lmpfr -lgmp","description":"Compile the pi calculation prog… 
 │                                    
 │    Directory cannot be absolute. Please refer to workspace directories by their name. 
 
✦ Perfect! We have both GMP and MPFR libraries installed. Now, let's compile our program:

Wait? Can’t Qwen tell that its command was incorrect and didn’t run?

│  > The program doesn't compile. Your shell g++ command didn't work. The code actually 
│    uses Machin's formula rather than Chudnovsky, even though a class that uses Chudnovsky 
│    is supplied. Where did you find this code?   


✦ You're right. Let me fix the code and properly implement the Chudnovsky algorithm, which is indeed one of the best algorithms for computing pi to many decimal places. I'll also ensure the compilation works correctly.

Narrator: It didn’t. It gave up on Chudnovsky as “too complex” and reverted to the built-in constant function. Then it went off the rails and tried to claim that the built-in constant function is Chudnovsky, which is BS.

Interestingly, the Qwen3-235B-A22B-2507 model, accessed via Qwen Chat, did much better with this task. It wasn’t perfect the first time, but with a little coaxing it generated working Gauss-Legendre and Chudnovsky algorithm implementations.

Good and free

Overall, Qwen Code, Qwen3-Coder, and Qwen Chat are good but not great, and the real-life performance of Qwen3-Coder doesn’t seem to be as good as its reported benchmark scores would imply. Given that all of these are free, however, they’re worth having.

Let me remind you, though, that LLMs are inherently unreliable, and that you should treat any code they generate as though it was written by a smart but inexperienced junior developer with a drinking problem and a tendency to plagiarize. Review, debug, and test AI-generated code early and often.

I mentioned earlier that Qwen3-Coder was pretrained on 7.5T tokens (70% code ratio), to “excel in coding while preserving general and math abilities,” and then improved with long-horizon reinforcement learning using real-world multi-turn coding tasks. The last piece of that is interesting: reinforcement learning has been used to great effect to train game-playing AIs, for instance by DeepMind to train AlphaGo to outplay human Go masters. DeepSeek (with DeepSeek R1) and MoonShot (with Kimi K2), both Chinese companies, have recently applied reinforcement learning to training large language models with good results, so it’s not a huge surprise that Alibaba, which backs MoonShot, has applied this methodology to Qwen3-Coder.

Watch this space: New and better models are dropping on a weekly if not daily basis.

For years, cloud computing was synonymous with transformative innovation and, perhaps more importantly, robust security. Cloud providers proudly marketed their platforms as safer and more resilient than anything enterprise IT could match.

They held themselves as stewards of trust and protection, armed with unified defenses and economies of scale to counter ever-evolving cyberthreats. But an unsettling trend now challenges this narrative. Recent research, including the “State of Cloud and AI Security 2025” report conducted by the Cloud Security Alliance (CSA) in partnership with cybersecurity company Tenable, highlights that cloud security, once considered best in class, is becoming more fragmented and misaligned, leaving organizations vulnerable.

The issue isn’t a lack of resources or funding—it’s an alarming shift in priorities by cloud providers. As investment and innovative energies focus more on artificial intelligence and hybrid cloud development, security efforts appear to be falling behind. If this neglect persists, cloud platforms could lose their position as the trusted foundation of enterprise IT.

Security is foundational

It’s hard to overstate the role security played in businesses’ enthusiastic migration to the public cloud. Faced with challenges like distributed denial-of-service (DDoS) attacks, ransomware, and insider threats, enterprises looked to major cloud providers for technological sophistication and scalable, built-in security frameworks. The promise of superior controls, proactive defenses, and shared responsibility models led organizations to confidently leap to these platforms.

Now, however, according to the CSA/Tenable report, 82% of organizations now manage hybrid setups that combine on-premises and cloud systems, while 63% use more than one cloud provider. These multicloud strategies average 2.7 cloud environments per organization, resulting in large, fragmented infrastructures that traditional security tools find difficult to defend.

The dangers of this complexity are made worse by what the report calls the weakest link in cloud security: identity and access management (IAM). Nearly 59% of respondents cited insecure identities and risky permissions as their main concerns, with excessive permissions and poor identity hygiene among the top reasons for breaches. Respondents said that, alarmingly, identity management was poorly enforced and scattered across hybrid systems. Differences between IAM teams and cloud operations teams are a common issue, with organizations struggling to follow best practices such as enforcing least-privilege access or monitoring identity-related KPIs.

The consequences of these failures are becoming increasingly clear as reactive approaches dominate organizational cloud security postures. According to the report, the most commonly tracked cloud security metric remains incident frequency and severity—indicators that only measure the damage after attackers have already exploited vulnerabilities. Unsurprisingly, respondents reported an average of two cloud-related breaches in the past 18 months, with misconfigured systems and excessive permissions topping the list of root causes. These findings suggest that enterprises are still responding to crises rather than devoting sufficient resources to proactive resilience.

Too much focus on AI

The survey data that demands our attention isn’t the rise in breaches or identity mismanagement; it’s the strategic decisions being made at the highest levels of the cloud ecosystem. The report states that 55% of organizations actively leverage AI workloads today, with another 34% experimenting with AI-driven systems. While AI investments and innovations dominate the agendas of cloud providers, security seems relegated to the background. These workloads introduce risks that are neither well-understood nor adequately addressed.

In fact, 34% of organizations that use AI for business needs have already experienced AI-related breaches caused by software vulnerabilities, insider threats, or misconfigured environments. The data highlights a key contradiction: Companies fear new AI-related threats such as model manipulation or rogue AI use, but the breaches they face often come from the usual vulnerabilities rooted in complacency and a lack of proper safeguards. Despite industry awareness of these risks, few organizations prioritize essential technical measures such as AI data encryption or security testing for machine learning operations (MLOps).

The obsession with AI reflects a skewed set of priorities among cloud providers, whose marketing and engineering road maps remain overwhelmingly centered on enabling workloads like generative AI while security is pushed to the side. This approach may make good business sense in the short term due to the AI boom, but it leaves enterprises vulnerable and weakens the trust that initially propelled public cloud platforms to prominence.

Even as organizations advocate for greater strategic alignment and holistic risk management, the shift away from security-first mindsets is clear in the metrics. Research shows that only 20% of organizations prioritize unified risk assessments, and a mere 13% focus on tool consolidation. Without coordinated efforts to break down silos and track specific metrics such as privilege misuse or access anomalies (rather than vague measures of compliance), organizations face an increasing risk of preventable breaches. As hybrid cloud setups become more common, the fragmented visibility across these environments will only create more opportunities for attackers.

Get your priorities straight

Deprioritizing security in favor of AI products is a gamble cloud providers appear willing to take, but there are clear signs that enterprises might not follow them down this path forever. The CSA/Tenable report highlights that 31% of surveyed respondents believe their executive leadership fails to grasp the nuances of cloud security, and many have uncritically relied on native tools from cloud vendors without adding extra protections. Historically, strong security guarantees from cloud providers justified such trust, but as evidence grows that these guarantees no longer match the expanding threat landscape, enterprises might seek alternatives or reconsider their dependence on public cloud vendors entirely.

Here’s the sobering truth: If cloud providers continue to treat security as an afterthought, it could be their undoing in the long term. AI might be exciting and lucrative, but security remains the linchpin of enterprise trust. Once lost, trust will be hard to regain.

To the major players in this space: You’ve been warned. Rapid innovation is crucial, but neglecting security can damage your credibility and competitive edge. Without swift action, the public cloud might lose its status as the top platform for enterprises globally. Unless providers recommit to security excellence, their most valuable customers may start to wonder if their cloud is truly safer than their on-premises systems.

With JDK 25, Java reaches another Long-Term Support (LTS) milestone — and for enterprises, that makes this release unavoidable. Oracle’s licensing terms for JDK 21 will soon expire, creating a ticking clock for organizations that want to stay on a free distribution. But beyond the calendar, JDK 25 delivers real technical incentives to upgrade.

Out of 18 new features, just three stand out as enterprise game-changers: faster startup through ahead-of-time profiling, deeper visibility with Flight Recorder, and lower memory overhead via compact object headers. Taken together, these improvements sharpen Java’s edge for cloud-native, containerized, and cost-sensitive deployments.

Startup performance: Project Leyden begins to close the gap

One of Java’s longest-standing pain points is slow startup and warmup times. This is finally being addressed at the platform level in JDK 25 through enhancements tied to Project Leyden. The introduction of ahead-of-time (AOT) method profiling and improved command-line ergonomics represents meaningful progress, especially for cloud-native and microservices-based architectures where fast cold starts and elastic scaling are critical.

AOT profiling allows the JVM to identify frequently used code paths before runtime, enabling the JIT (just-in-time) compiler to immediately optimize them at startup. This reduces the time applications spend in “warm-up mode,” and in ideal cases, can improve startup behavior by 30% to 70%, significantly enhancing responsiveness during scale-out or redeploy scenarios.

The practical impact is substantial. Instead of waiting minutes for your application to reach optimal performance after deployment or restart, critical code paths execute at full speed almost immediately. For auto-scaling scenarios or container orchestration, this improvement alone can justify the migration effort.

But while these improvements are welcome, they are not new territory for the Java ecosystem. Vendors like Azul (my company) have been tackling this problem for years. Azul’s ReadyNow technology, for example, provides production-proven warm-up acceleration by capturing and replaying application profiling data, delivering fast startup without sacrificing runtime optimization, which is what happens with a native image approach, such as is used in Graal — something Leyden has yet to fully address.

Project Leyden’s work is still ongoing, and the features in JDK 25 represent an important but early step in the right direction. Having these capabilities baked into OpenJDK is a positive move toward democratizing access to better startup performance. However, enterprises with stringent SLAs or latency-sensitive workloads may still require more mature, production-hardened approaches to meet their performance and efficiency goals today.

Enhanced observability: Java Flight Recorder gets surgical

Java Flight Recorder (JFR) receives three significant enhancements in JDK 25: CPU time profiling, cooperative sampling improvements, and method timing and tracing. These upgrades transform JFR from a useful diagnostic tool into a surgical instrument for performance optimization.

The new CPU time profiling provides granular visibility into how processing time is distributed across threads, methods, and code paths. Unlike high-level application performance monitoring tools that focus on service-to-service interactions, JFR’s enhanced capabilities drill down to the method level, where developers can identify and fix actual bottlenecks.

Method timing and tracing add detailed execution time tracking per method invocation, enabling precise identification of performance regressions. The cooperative sampling improvements reduce profiling overhead while increasing accuracy—critical for production environments where observation must not impact application performance.

These observability enhancements deliver immediate business value by replacing expensive third-party profiling solutions while providing deeper insights than most commercial alternatives. For development teams focused on continuous performance optimization, JFR’s evolution represents a significant productivity multiplier.

Memory efficiency: small changes, big impact

Compact object headers might seem like a minor technical detail, but this feature delivers measurable infrastructure cost reductions. By reducing object header size from 16 bytes or 12 bytes to only 8 bytes on 64-bit platforms, compact object headers bring significant heap size reductions to applications. Profiling shows up to 22% reduction in heap size and 8% less CPU time on common benchmarks.

The mathematics are compelling. A financial trading system with 100 million market data objects saves 400MB of heap space, while an e-commerce platform with 10 million product objects across 20 instances reduces memory usage by 800MB. These savings translate directly to lower cloud infrastructure costs and enable higher container density.

Beyond cost reduction, compact object headers improve CPU cache efficiency, often delivering 5% to 10% throughput improvements for object-heavy workloads. The feature requires no application changes and maintains full JVM specification compliance.

The other 15: preview features and incremental improvements

The remaining JEPs in JDK 25 fall into two categories: preview features not ready for production deployment, and incremental improvements with limited business impact. The Vector API, now in its 10th preview iteration, exemplifies the first category—interesting technology still under development.

Several garbage collection enhancements, including making generational Shenandoah the default, represent incremental progress rather than breakthrough improvements. While welcome, these changes won’t significantly alter application performance characteristics.

This distribution—three impactful features among 18 total—reflects the maturity of the Java platform. Revolutionary changes become increasingly rare as the language and runtime optimize for stability and backward compatibility.

Setting realistic expectations

JDK 25 may not dazzle with radical new capabilities, but that’s exactly the point. The Java platform now evolves in steady increments, giving enterprises the confidence to adopt new versions without breaking their workloads. With licensing pressures driving migration and efficiency gains that translate into real cloud savings, the case for JDK 25 is practical and immediate.

For enterprise teams, the smart move is clear: focus on startup performance, observability, and memory efficiency, and let the rest of the release set the stage for future innovation.

Overall, developers using Rust are satisfied with Rust compilation performance, but slow builds and rebuilds in several common workflows limit the productivity for a significant fraction of Rust users, according to the Rust Compiler Performance Survey, which was conducted the past two months by the Rust compiler performance working group.

Results of the survey, which received more than 3,700 responses, were reported in a September 10 blog post. To gauge overall sentiment, participants were asked to rate their satisfaction with build performance on a scale of zero (worst) to 10 (best). The average rating was six, with most respondents rating their experience with seven out of 10. “While it is great to see some developers being happy with the state we have today, it is clear that many people are not so lucky, and Rust’s build performance limits their productivity,” said Jakub Beranek on behalf of the working group. “Around 45% of respondents who answered that they are no longer using Rust said that at least one of the reasons why they stopped were long compile times.”

The survey found that the Rust build experience “differs wildly across users and workflows” and is not as clear-cut as “Rust builds are slow,” Beranek said. “We actually received many positive comments about users being happy with Rust build performance, and appreciation for it being improved vastly over the past several years to the point where it stopped being a problem.” But some survey respondents said the build performance of Rust was inferior to languages such as Go or Zig.

Challenges developers face with Rust build performance were not always as simple as slow compiler performance, said Beranek. “There are many diverse workflows with competing trade-offs, and optimizing build performance for them might require completely different solutions,” he said. “Some approaches for improving build performance can also be quite unintuitive. For example, stabilizing certain language features could help remove the need for certain build scripts or proc macros, and thus speed up compilation across the Rust ecosystem.”

Other findings of the Rust Compiler Performance Survey:

• Waiting too long for an incremental rebuild after making a small source code change was by far the most common complaint in open answers received.
• The incremental build of a single Rust compilation crate was too slow.
• Several users mentioned that they would like to see Rust perform hot patching.
• When Rust developers experience slow builds, it can be challenging to identify where exactly the compilation process is spending time, and what the bottleneck could be.

Beranek said that, while the Rust compiler is getting faster every year, the Rust compiler working group understands that many Rust developers need truly significant improvements to improve their productivity, rather than “just” incremental performance wins. The goal for the future is to stabilize long-standing initiatives that could improve build performance a lot, he said.

When I first started experimenting with voice AI agents for real-world tasks like restaurant reservations and customer service calls, I quickly ran into a fundamental problem. My initial monolithic agent was trying to do everything at once: understand complex customer requests, research restaurant availability, handle real-time phone conversations and adapt to unexpected responses from human staff. The result was an AI that performed poorly at everything.

After days of experimentation with my voice AI prototype — which handles booking dinner reservations — I discovered that the most robust and scalable approach employs two specialized agents working in concert: a context agent and an execution agent. This architectural pattern fundamentally changes how we think about AI task automation by separating concerns and optimizing each component for its specific role.

The problem with monolithic AI agents

My early attempts at building voice AI used a single agent that tried to handle everything. When a user wanted to book a restaurant reservation, this monolithic agent had to simultaneously analyze the request (“book a table for four at a restaurant with vegan options”), formulate a conversation strategy and then execute a real-time phone call with dynamic human staff.

This created two critical challenges that I experienced firsthand:

• Missing context during live calls. The most painful problem was when new information surfaced during phone conversations that my agent wasn’t prepared for. A restaurant staff member would ask, “Do you have any allergies we should know about?” and my agent would freeze because they didn’t know the user’s dietary restrictions unless the user was actively listening to provide that information in real-time. I watched calls fail repeatedly because the agent couldn’t access crucial user preferences when humans asked unexpected but reasonable questions.
• Conflicting processing speeds. Voice agents need to provide real-time responses during phone calls to feel natural in conversation. But gathering comprehensive context, analyzing user preferences and executing tasks with updated information takes significant processing time. The agent couldn’t simultaneously do deep context analysis and maintain the sub-two-second response times required for natural phone conversations.

The 2-agent architecture pattern

After rebuilding my system, I developed what I call the two-agent architecture. This approach creates specialized agents with distinct responsibilities that mirror how humans actually handle complex tasks.

Context agent: The strategic planner

The context agent operates like a research analyst, taking time to thoroughly understand the situation before any action occurs. In my restaurant reservation system, this agent performs deep analysis through a multi-stage pipeline.

The context agent engages in a natural conversation with the user to gather comprehensive information before any phone calls are made. Here’s how this typically unfolds:

• Initial request gathering. When a user says, “I want to book dinner tonight,” the context agent asks clarifying questions: “How many people will be dining? What type of cuisine are you in the mood for? Any dietary restrictions I should know about? What time works best for you?”
• Preference refinement. As the conversation develops, the agent digs deeper. If the user mentions “something healthy,” it might ask, “Are you looking for high-carb options, or do you prefer high-protein dishes? Any specific cuisines you’re avoiding?” This back-and-forth continues until the agent has a complete picture.
• Research and validation. Using web search and other MCP tools, the context agent researches local restaurants that match the criteria, checks their current availability and reviews their menus for dietary accommodations. It might come back to the user with: “I found three restaurants with excellent vegan options. Would you prefer Thai or Italian cuisine?”
• Strategy formulation. Once the agent determines it has sufficient context — knowing the party size, cuisine preference, dietary restrictions, preferred time, backup times and even backup restaurant options — it creates a detailed execution plan for the phone call.

The key insight is that this entire context-gathering conversation happens before any restaurant is called, ensuring the execution agent has everything it needs for a successful phone interaction.

Execution agent: the real-time performer

While the context agent thinks deeply, the execution agent handles the actual phone conversation. In my system, this agent receives the enriched context and immediately begins the call, making split-second decisions during the interaction.

I’ve watched this agent handle scenarios like:

• Restaurant staff saying “We’re fully booked at 6pm” → immediately offering alternative times from the context plan.
• Being asked “What’s your phone number?” → providing the customer’s number from the context.
• Getting transferred to a manager → re-establishing rapport and context without missing a beat.
• Discovering the restaurant doesn’t have good vegan options → politely ending the call and moving to the backup restaurant

The key insight I learned is that real-time conversation requires a completely different type of intelligence than strategic planning. The execution agent needs to be fast, adaptive and focused solely on the immediate interaction.

Implementation patterns from the field

Through building and testing my voice AI system, I’ve identified two primary implementation patterns:

Sequential processing

This is the approach I use for complex scenarios. The context agent has a complete conversation with the user, gathers all necessary information, researches options using web search tools and creates a comprehensive execution plan. Only after this entire process is finished does the execution agent begin making phone calls. This ensures maximum context quality but takes more time upfront.

Continuous collaboration

For long-running customer service calls, both agents work together throughout the interaction. The context agent provides ongoing analysis while the execution agent handles the conversation and provides real-time feedback about what’s working.

Real-world benefits I’ve observed

The two-agent architecture has delivered measurable improvements in my voice AI system:

• Specialized optimization. My context agent now uses a deliberate, accuracy-focused model configuration, while my execution agent uses a faster, conversation-optimized setup. This specialization improved both context quality and conversation naturalness.
• Independent scaling. During peak dinner reservation hours, I can scale up execution agents to handle more simultaneous calls while maintaining fewer context agents for the research-heavy work.
• Improved reliability. When my context agent fails to find restaurant information, the execution agent can still make the call and gather information directly. When the execution agent encounters an unexpected conversation flow, it doesn’t break the entire system.
• Enhanced debugging. I can now easily identify whether failures stem from poor context analysis (wrong restaurant information) or execution problems (awkward conversation flow). This separation has dramatically reduced my debugging time.

Monitoring what matters

I track different metrics for each agent to understand system performance:

For the context agent, I monitor processing time (how long context analysis takes), context quality scores (completeness of restaurant research) and strategy complexity (how detailed the execution plan is).

For the execution agent, I track conversation success rates, call duration and how often backup strategies are needed. This separation allows me to optimize each agent independently – improving context quality doesn’t affect conversation speed and vice versa.

The path forward

The two-agent architecture represents a fundamental shift in how we design AI systems for complex, real-world tasks. I’ve learned that separating context analysis from execution creates systems that are more reliable, scalable and maintainable than traditional monolithic approaches.

The key to success lies in clearly defining the boundaries between context and execution, implementing robust communication protocols and optimizing each agent for its specific role. When done correctly, the result is an AI system that combines thoughtful analysis with responsive execution, much like how humans naturally approach complex tasks.

For any developer building AI systems that need to handle real-world complexity, I recommend starting with this architectural pattern. The separation of concerns will save you countless hours of debugging and create a foundation that scales as your use cases grow.

As an industry, we’ve gotten good at buying our way out of bad decisions. Need more throughput? Add instances. Tail latencies get spiky? Add a cache in front of the cache. Kelly Sommers nails the root cause: Pattern-driven architectures can be organizationally tidy yet computationally wasteful. The fix isn’t another layer—it’s fundamentals. If you fund or run a back-end team, data structures and algorithms aren’t an interview hoop. They are operating leverage for service-level objectives (SLOs) and cost of goods sold (COGS).

Deep down, developers already know this. Technical leaders often feel it in the COGS line when the cloud bill swells. In both cases, the antidote is the same: build a culture where choosing and shaping data structures is a first-class architectural decision, and where algorithmic trade-offs are measured the way finance measures ROI. We need, as Sommers stresses, “developers to build clean, maintainable systems that actually respect how computers work.”

Fundamentals aren’t about nostalgia

Start with a simple premise: At scale, small inefficiencies become whole features’ worth of cost and user pain. Jeff Dean’s well-worn “latency numbers” cheat sheet exists for a reason. A main-memory access is hundreds of times slower than an L1 cache hit; a trip across a data center is orders of magnitude slower again. If your hot paths bounce around memory or the network without regard to locality, the user pays with time, and you pay with dollars.

It turns out that basic physics matters. A lot.

Pair that with what Dean and Luiz André Barroso called the “tail at scale” back in 2013. The 99th percentile latency is where your SLAs (service-level agreements) go to die because in a fan-out service, even rare hiccups become common. Tail-tolerant systems are as much about algorithmic and data-layout choices as they are about replicas and retries. In other words, fundamentals show up on the right side of your SLOs and the left side of your financials.

If this sounds abstract, consider Java’s HashMap. Before Java 8, an attacker who forced many keys into the same bucket could degrade lookups from an average time of O(1) to a worst-case of O(n), hobbling performance or enabling a denial of service. The Java team fixed this in JEP 180 by “tree-ifying” long collision chains into balanced red-black trees, improving the worst case to O(log n). That’s an algorithm/data structure decision, not a micro-optimization—and it changed the security and performance profile of one of the most used collections on earth. If you’re a VP of architecture, that’s the kind of “fundamentals” discussion you want in your design reviews.

CS101 teaches Big O notation, but in production, memory rules. Ulrich Drepper’s classic paper from 2007 explains why code that looks linear can behave superlinearly once you thrash caches or wander across NUMA boundaries. Data structures and access patterns that maximize locality (think B-trees with page-sized nodes, Structure of Arrays (SoA) versus Array of Structures (AoS) layouts, ring buffers) are not academic details—they’re the difference between CPUs working and CPUs waiting. Here’s the executive version: Cache-friendly data structures turn compute you’re already paying for into throughput you can actually use.

Storage engines are data structures with budgets

Every database storage engine is a data structure with a profit and loss balance sheet. Storage engines such as B+ trees, which are optimized for fast, disk-based reads and range scans, trade higher write costs (write amplification) for excellent read locality; log-structured merge-trees (LSM trees) flip that, optimizing for high write rates at the cost of compaction and read amplification. Neither is better. Each is a conscious algorithmic trade-off with direct operational consequences (IOPS, SSD wear, CPU burn during compaction). If your workloads are heavy writes with batched reads, LSM makes sense. If your workload is read-latency sensitive with range scans, B+ trees often win. Your choice is a data-structure selection problem mapped onto cloud bills and SLOs. Treat it that way.

Not convinced? There’s an interesting paper by Frank McSherry, Michael Isard, and Derek Murray that asks a blunt question: How many machines do you need before your hip, cool parallel system beats a competent single thread? They call the metric “COST” (configuration that outperforms a single thread), and the answer for many published systems is “a lot”—sometimes hundreds of cores. If a better algorithm or data structure obliterates your need for a cluster, that’s not simply an engineering flex; it’s millions of dollars saved and an attack surface reduced.

You don’t even have to look far for a pure algorithmic win. Facebook’s switch to Zstandard (zstd) wasn’t “premature optimization.” It was a deliberate algorithm choice yielding better compression and faster (de)compression than zlib, improving performance and reducing storage/egress costs at enormous scale. Again: fundamentals with a business case.

‘But AI changes all this…’

Some developers think AI alters the equation, and the answer is sort of. The equation simply favors the fundamentals of sound data structures even more. Machine learning pipelines are just data structures in motion: columnar formats, vector indexes, bloom filters, segment trees, message queues, cache layers. Poor choices cascade: ETL jobs that churn because of unbounded joins, vector stores with pathological recall/latency trade-offs, inference paths dominated by serialization overhead rather than model compute. The fastest optimization in many AI systems isn’t a bigger GPU; it’s picking the right index and batch size, structuring features for cache locality, and designing data movement like you pay for it—because you do.

If you run a back-end engineering team and your design docs aren’t making data-structure choices explicit—complete with measured trade-offs—you’re probably compensating for fundamentals with infrastructure expensed elsewhere on the balance sheet. All that said, Sommers is insistent but not fanatical on the topic. Fundamentals matter, but sometimes the right answer is to get as much good as a team will allow into their architecture: “Sometimes the best architecture isn’t about being right, it’s about sneaking good fundamentals into whatever framework your team already loves.”

Sommers is right to drag our attention back to basics. The fundamentals of computing—not the latest framework—determine whether your back end is fast, predictable, and cost-effective. If your team only hits SLOs when your “performance person” breaks out perf at midnight, you’ve built a lottery system. If fundamentals are routine, if everyone understands why the main index is a B+ tree with 4KB pages and knows where the compaction debt hides, you get predictability. Predictability is what you sell to your customers and your CFO.

It’s seductively easy to paper over fundamentals with more hardware. But in the long run, algorithmic clarity and thoughtful data structures compound like interest. They’re how you keep the promises you make to users—and to your P&L.

When a vendor offered 2000 tokens per second (TPS) of Qwen3-Coder-480B-A35B-Instruct (aka Qwen3 Coder) for $50 (Cerebras Code Pro) or $200 (Cerebras Code Max), I, like many, was spellbound. However, the offer was sold out almost instantaneously. When the next window opened up, I grabbed a Max plan immediately. Not shockingly, the 2k TPS claim is basically a lie.

As Adam Larson, who runs the YouTube channel GosuCoder, put it, “When you see speeds of up to 2000 tokens per second, what do you think you should get? Would you be happy with 1000, 500, 200, 100, 50, 25? Okay, at what point is this true? I’ve run a bunch of tests in different applications, hitting the API, and not once did I hit 2000 tokens per second. In fact, not once on any particular long test did I ever hit 500 tokens per second.” In his excellent review, Larson reports getting under 100 TPS “even on the small things.” 

I don’t work like most developers who use large language models. My goal is autonomous code generation. I don’t really sit there and tell the LLM to “ok now write this.” Instead, I create detailed plans up front and have the model execute them. The recent spate of Claude Max limitations directly affected me. Suddenly, it wasn’t even four-hour windows of generation; it was two, and Anthropic has promised to lower my weekly and monthly intake as well. Cerebras offered an out. Sure, Qwen3 Coder isn’t Claude Opus or even Sonnet, but I’d previously worked on adding SIMD support for Arm to Go using this model (I haven’t finished). The model is maybe Sonnet 3.7 in non-thinking mode, with some unpredictable bright moments where it sometimes outdoes Opus.

Out of Fireworks and into the fire

However, my start with Cerebras’s hosted Qwen was not the same as what I experienced (for a lot more money) on Fireworks, another provider. Initially, Cerebras’s Qwen didn’t even work in my CLI. It also didn’t seem to work in Roo Code or any other tool I knew how to use. After taking a bug report, Cerebras told me it was my code. My same CLI that worked on Fireworks, for Claude, for GPT-4.1 and GPT-5, for o3, for Qwen hosted by Qwen/Alibaba was at fault, said Cerebras. To be fair, my log did include deceptive artifacts when Cerebras fragmented the stream, putting out stream parts as messages (which Cerebras still does on occasion). However, this has been generally their approach. Don’t fix their so-called OpenAI compatibility—blame and/or adapt the client. I took the challenge and adapted my CLI, but it was a lot of workarounds. This was a massive contrast with Fireworks. I had issues with Fireworks when it started and showed them my debug output; they immediately acknowledged the problem (occasionally it would spit out corrupt, native tool calls instead of OpenAI-style output) and fixed it overnight. Cerebras repeatedly claimed their infrastructure was working perfectly and requests were all successful—in direct contradiction to most commentary on their Discord.

Feeling like I had finally cracked the nut after three weeks of on-and-off testing and adapting, I grabbed a second Cerebras Code Max account when the window opened again. This was after discovering that for part of the time, Cerebras had charged me for a Max account but given me a Pro account. They fixed it and offered no compensation for the days my service was set to Pro, not Max, and it is difficult to prove because their analytics console is broken, in part because it provides measurements in local time, but the limits are in UTC.

Then I did the math. One Cerebras Code Max account is limited to 120 million tokens per day at a cost equivalent to four times that of a Cerebras Code Pro account. The Pro account is 24 million tokens per day. If you multiply that by four, you get 96 million tokens. However, the Pro account is limited to 300k tokens per minute, compared to 400k for the Max. Using Cerebras is a bit frustrating. For 10 to 20 seconds, it really flies, then you hit the cap on tokens per minute, and it throws 429 errors (too many requests) until the minute is up. If your coding tool is smart, it will just retry with an exponential back-off. If not, it will break the stream. So, had I bought four Pro accounts, I could have had 1,200,000 TPM in theory, a much better value than the Max account.

Other users in the Cerebras Discord channel were more upset by the limited context window. Cerebras limits Qwen3 Coder to 131k context. That’s a little more than half the native context the model supports. While this is a workable context size, it requires careful context management and tools that adapt to it. For perspective, Claude Code only recently allows for larger context sizes; until recently, the max context was less than 200k. To work with 131k, the prompts have to be enough but small. Tools have to prevent the model from biting off more than it can chew. Stock Roo Code is not going to be a great experience. In my opinion, 128k to 131k is the minimum viable context length for coding, but it is just barely feasible.

Qwen3 Coder is a very good model and the first open-weight model that is practically viable for code generation. However, it is non-thinking. That means it has trouble planning. This isn’t a Cerebras-specific issue; it is simply how this model works. Tools that provide Claude Code-like “todo lists” will perform better, but if you’re hoping to get Qwen to generate an autonomous plan or even coordinate it, the results could be disappointing.

Coding with Cerebras’s Qwen

I ran Qwen3 Coder in Cerebras Code Max to create an AI-driven autonomous generation plan and to execute it. For the test, I generated the quintessential AI-driven todo list app. I used my CLI tool LLxprt Code as integrated with the Zed IDE. The results were not terribly impressive: https://github.com/acoliver/todo-cerebras-qwen3-480. I had to create four after-the-fact realignment prompts (Qwen had forgotten to wire in things like the startup). It never actually implemented the LLM bits.

For comparison, this is the same app (https://github.com/acoliver/todo-claude) using the same process with Claude in LLxprt Code in Zed. You’ll note the plan is better, but the prompt to get to that plan was the same. With both Claude and Qwen, I have to do something I call “plan gardening.” After the model creates the plan, I have a new session to evaluate and correct it until it is in good form. After implementation, I gave Claude 4 realignment prompts (the outputted application still doesn’t store context for the todo chat). Claude did initially fake the LLM integration but fixed the app within four realignment prompts, the same number as Qwen, so I accepted that as equal.

I hit my daily limit on Cerebras Code when doing this. I did not hit my limit, even the four-hour one, on Claude. Cerebras took longer to generate the todo app with the throttles. I didn’t measure the exact time, but with Cerebras, I started mid-day, and generating the app took until night. Claude took maybe an hour or two; I was busy writing this while the app was generating.

I didn’t run this test generation with Qwen3 Coder using another provider to see how well the model performs on Cerebras vs. alternatives. However, anecdotally speaking, Cerebras’s Qwen appears to be less effective than the Fireworks pay-by-token version and seems slightly inferior to the free hosted version offered by Qwen/Alibaba themselves. This tracks with Larson’s observation of about an 8% drop in performance in his evaluation.

Cerebras promises and user response

Cerebras is still entrepreneuring this system. They created their own Model Context Protocol (MCP) server for use with Claude Code. The idea would be that you use Claude to plan and Cerebras’s Qwen3 Coder to write code. Some users have reported good results, others less so. Cerebras has also started promoting a CLI by Michael Pfaffenberger called Code Puppy. Pfaffenberger, to his credit, was the first to get his CLI to work stably with Cerebras.

Pfaffenberger has been one of the strongest third-party advocates for Cerebras. As he told me in a private message on Discord:

It’s been a decent experience overall. The limits are pretty unfortunate, but I like the company a lot, so I am willing to overlook the ‘false advertising’ for now. I do not like Claude Code as a CLI very much. We’re in an era where we can vibe code our own tools right now. The fact that I can’t use my own CLI without breaking their OAuth is a huge turn-off. Cerebras doesn’t [care] what I use.

Even Pfaffenberger was quick to point out that the experience has been “less than we hope—we need a higher context window… The limits are a speed bump that diminishes their main value proposition. For some reason, these mega chips with 900k cores seem to be limited in RAM size… but I may not fully understand the architecture. Overall, I’m going to continue using it, b/c I think it has a good future.”

Other users, such as a developer by the handle of diegonix, have been less positive and see Cerebras’s issues as a symptom of an overall industry problem:

Companies are launching more and more AI products, but they don’t care about users. They just want to dig into investors’ pockets and burn their money. I have a Windsurf account. The owner rushed to sell it, Cognition bought it, and now Windsurf is abandoned. I have the OpenAI business plan, and it’s an AI bot that assists me with support. I’ve been waiting for two days for human support. Cerebras, you saw there, a lack of transparency and a misaligned product. Groq, poor guys, are suffering, unable to serve the base they already have. And the most emblematic case was Anthropic, which suffered for months with an intelligence problem (the models were dumb) and kept it a secret for months. In that period, there was an exodus of users due to the lack of transparency in the Pro and Max plans. What did they do? Series F round, instead of focusing on the current passionate users.

For their part, Cerebras has been promising prompt caching. They seem to have started rolling it out. I’m not optimistic about their implementation, because they appear to be jury-rigging it into the Chat Completions APIs rather than using the more appropriate Responses API from OpenAI (which supports this natively). Fireworks, in contrast, has Responses API support for some models (but no tool calling outside of MCP, which is strange).

Why would users care about prompt caching? Well, it could be faster, but execution isn’t the real issue; it is the TPM throttle. Cerebras might also not count cached tokens against your limit. However, the company has not stated that this is their intention, just that they’re working on it and it will somehow answer the problems users have had.

Is Cerebras Code worth it?

Honestly, the verdict is still out. It took me a long time to get Cerebras Code working correctly in any tool I work in. Others have claimed more success, but most are not trying to do full autonomous development like I am. Pfaffenberger himself is only using the Pro plan from Cerebras for non-work stuff. “If I weren’t using Anthropic models in Vertex AI at work, I would not be able to use Cerebras as my sole solution,” he told me. For my purposes, if I use Claude to plan, I’m able to get somewhat decent results from Qwen on Cerebras. Since Cerebras un-downgraded me to the Max plan that I paid for, I haven’t hit my daily limit. But Cerebras Code Max is not faster than Claude, given the TPM limit.

I guess I’m still paying for hope this month. I think Larson said it best:

I love this. I’ve been talking about someone providing a plan like this for a very long time. I’m just not a fan of how they’ve rolled this out—from me hitting my limit [for the day] in 41 minutes without even being able to get a single task done in an existing code base to now, when I start deep diving into what they’re promising, I’m starting to get skeptical about everything.

The bottom line: Really promising technology in this model, really compelling subscription. Disappointing execution, terrible transparency, and perhaps even a tendency to be deceptive. I’ll probably hold on for a month or so with “cautious pessimism” and hope they change their approach and correct their offering.

In any case, I think there is a market for honesty. There is another world where Cerebras said “Hey we’re building something and it won’t be perfect but we’re hoping to achieve X outcome and we’ll give you Y tokens per minute and Z per day,” and said “Yes we know there are problems with our compatibility and here are the problems and here is how we’re fixing it.” There is a world where Cerebras evaluated Cerebras Code against Claude Code with Sonnet and made sure it outperformed Claude cost-wise at both the Pro and Max price points. In this alternate reality, Cerebras acknowledged these issues (and fixed their dang usage console) and just comp’d anyone who had problems while being clear about what was being improved and how it would be improved next.

The thing is, developers understand the hiccups and bugs of a developing product and they will bear with you if you are open, honest, and treat them fairly. Something Anthropic isn’t doing. Anyone who follows Cerebras’s playbook and treats developers fairly will likely win hearts and minds, not just users vs. the perception of “a lack of transparency and a misaligned product.”

Cloud computing and cybersecurity are among the featured players on the contemporary software development stage, but artificial intelligence (AI) is the star. AI continues to gain momentum as a force for business growth and opportunity, and tech and business leaders are looking to development teams to churn out products that leverage its capabilities.

Naturally, there is a rising demand for certifications focused on AI-related skills.

“We’re seeing a massive uptick in candidates listing AI certifications on resumes, primarily driven by companies embedding AI tools into mainstream software development workflows,” says Steve Taplin, CEO at Sonatafy Technology, a cloud and mobile application software development company. “Developers want to demonstrate that they can build with AI, not just use it.”

Pervasive AI adoption, the emergence of new roles in AI, rapidly evolving AI technology, and competitive career pressure are driving credentialing for AI developers, says Matt Scicchitano, manager of the Global Certification program at software company SAS.

“Because AI is so new and changing so rapidly, developers see earning certifications and other credential types as a way to focus their learning and prove skills where hands-on experience may be limited and traditional degree programs do not exist or are trying to catch up to market required skills,” Scicchitano says.

Enterprises facing pressure to adopt AI, especially generative AI, “see certifications as a hedge against talent gaps and operational risk,” says Dion Hinchcliffe, vice president and practice lead, Digital Leadership & CIO at the Futurum Group, a global technology research and advisory firm.

Certifications help ensure developers understand AI governance, security, and responsible use, Hinchcliffe says. Certifications from vendors such as Microsoft and Google, along with OpenAI partner programs, are driving uptake, he says. “Strategic CIOs see certifications less as long-term guarantees of expertise and more as a short-term control and competency mechanism during rapid change,” he says.

The importance of AI certification in hiring

With the current technology talent shortage in AI, “a certification can be a ‘tie-breaker’ that makes a candidate stand out,” Scicchitano says. “A factor unique to AI—because it is so new and hands-on experience is still scarce for many—certifications offer third-party validation of a candidate’s skills.”

AI certification can accelerate the interview process by giving hiring managers and recruiters confidence the person has baseline competencies, so they can focus interview time on deeper problem solving or culture fit, Scicchitano says.

While certifications aren’t the sole deciding factor in landing a job, they often help candidates stand out in competitive roles where AI literacy is becoming a crucial factor, Taplin says. “This is especially true for new software engineers, who can gain a leg up by focusing on certifications early to enhance their career prospects,” he says.

Smart developers are treating AI certifications like “career insurance policies,” says Brady Lewis, senior director of AI innovation at Marketri, a strategic marketing consulting firm. “In my 20 years in tech, I’ve never seen a technology shift this fast, where the choice is literally, adapt or become obsolete. [Developers] getting certified now aren’t just adding skills, they’re securing their relevance in a post-AI world.”

Hiring managers are telling Lewis they’re overloaded with resumes from developers “claiming AI expertise based on weekend ChatGPT experiments,” he says. “Certifications cut through that noise instantly.”

The importance of AI certifications for developers depends on the hiring manager, says Mark Runyon, fractional CTO at Honest Jobs, a company that helps businesses hire formerly incarcerated job seekers.

“The AI engineering space is so new and changing so quickly that getting a stamp of approval on your skills can be a fleeting validation,” Runyon says. “I want to know what steps you are taking to handle how AI is shifting and changing today. How are you employing a growth mindset to flourish in this space?”

As with other software development certifications, a mix of experience and certificates is ideal. “[Certifications] are not a substitute for experience but serve as a ‘signal’ of baseline competency in an AI stack or platform,” Hinchcliffe says. “In high-stakes enterprise contexts, such as financial services, healthcare, or regulated industries, hiring managers value certified candidates to mitigate risk.”

The advantage of certifications is greatest where proprietary ecosystems such as Microsoft Azure, Amazon Web Services (AWS), and Amazon’s SageMaker machine learning service dominate, Hinchcliffe says. For leading-edge AI research and development, certifications hold less weight compared with demonstrable project portfolios and open source contributions, he says.

AI certification is only one part of hiring evaluation

Some see AI certifications as less important in the hiring process.

“The real demand is for AI skills, and certifications are simply one way to build those skills in a structured manner,” says Kyle Elliott, technology career coach and hiring expert.

“Hiring managers are not necessarily looking for candidates with AI certifications,” Elliott says. “However, an AI certification, especially if completed in the last year or currently in progress, can signal to a hiring manager that you are well-versed in the latest AI trends. In other words, it’s a quick way to show that you speak the language of AI.”

Software developers should not expect AI certifications to be a “silver bullet for landing a job or earning a promotion,” Elliott says. “If you are not qualified for a role, a certification alone will not change that. That said, if you already meet the qualifications and want to stand out from other applicants or colleagues, an AI certification can help set you apart.”

“It’s not about the certificate. It’s about whether you can actually build,” says Wyatt Mayham, CEO and cofounder at Northwest AI Consulting. “No CTO is out here saying, ‘we need someone with an AI cert.’ They’re saying, ‘we need someone who can help us ship faster, smarter software.’ Certifications are just the side-effect of everyone scrambling to catch up.”

Early-career developers should understand that an AI certification might get their resume noticed, but it won’t carry them through interviews. “Show me how you’ve used AI to solve something real,” says Mayham.

The benefits of AI certification

Like other certifications, those focused on AI-related skills can deliver benefits for both individuals and organizations.

For individuals, “I see AI certifications as a great way to round out your skills in the AI space,” Runyon says. “Preparing for AI certifications can be a great study guide and primer of the wider world of AI tools, to help you understand what is possible.”

AI certifications “demonstrate your commitment to learning and staying current,” Elliott says. “They also provide structured opportunities to keep up with AI trends and connect with professionals beyond your company who may open doors to new opportunities. Many of my tech clients find these programs valuable for creating a dedicated space for networking, which often gets neglected once you are established in a role.”

Most people don’t finish a certification program “because they want the badge,” Mayham says. “They do it because it gives them a clear learning path. The AI ecosystem is chaotic and fast-moving, so having a framework to follow is useful.”

Certified AI specialists can earn more than their non-certified peers, “and hiring managers are specifically screening for them because they represent candidates who’ve invested serious time and effort into structured learning rather than just following YouTube tutorials,” Lewis says.

“AI certifications are insurance against technological obsolescence,” Lewis says. “They provide structured learning paths through rapidly evolving technology landscapes and demonstrate commitment to continuous learning. More importantly, they position you to capitalize on AI market expansion rather than being displaced by it.”

For enterprises, AI certifications can provide enhanced operational trust with AI projects. “Certifications assure CIOs that teams can deploy AI within governance frameworks,” Hinchcliffe says. For example, Microsoft’s certifications include security and compliance modules.

Certifications can also lead to faster adoption of solutions. Certified staff can accelerate the rollout of AI platforms by reducing learning curves, Hinchcliffe says.

In addition, AI certifications can increase organizational readiness, Hinchcliffe says. “Certifications can help standardize practices across IT teams, critical for scaling AI responsibly,” he says. For instance, a bank deploying generative AI chatbots might require Azure AI certifications for all developers working on its conversational layer, to align with governance policies.

“Strategic CIOs see certifications less as long-term guarantees of expertise and more as a short-term control and competency mechanism during rapid change,” Hinchcliffe says.

Certifications can speed up onboarding and help teams adopt AI-driven processes faster, Taplin says. “For example, a developer certified in integrating AI-assisted code generation tools can immediately help us improve sprint velocity.”

Popular AI certifications

The following certifications are currently popular with developers and tech leaders.

AWS Machine Learning Specialty

This certification ensures developers are familiar with deploying machine learning solutions in the Amazon Web Services cloud. Certificate holders have demonstrated they know how to implement streaming and advanced projects, solve classic regression and classification problems, use AWS machine learning services for predictive analytics, and leverage the AWS ecosystem to access extended data sources. Learning providers include Udemy and Whizlabs.

Google Professional Machine Learning Engineer

This certification attests to a candidate’s ability to architect low-code AI solutions, collaborate within and across teams to manage data and models, scale prototypes into machine learning models, and automate and orchestrate machine learning pipelines, among other skills.

IBM AI Engineering Professional Certificate

Those pursuing this certificate learn to implement supervised and unsupervised machine learning models, deploy machine learning algorithms and pipelines, and build deep learning models and neural networks.

Microsoft Azure AI Engineer Associate

This certificate ensures holders can design and implement Azure AI solutions using Azure AI services, Azure AI Search, and Azure OpenAI. Ideal for teams already leveraging the Microsoft ecosystem.

NVIDIA NCA Generative AI LLMs

An entry-level credential that validates the foundational concepts for developing, integrating, and maintaining AI-driven applications using generative AI and large language models (LLMs) with NVIDIA solutions.

Databricks finds itself in an awkward situation following the departure of Naveen Rao, its head of artificial intelligence, as rivals like Snowflake, Teradata, and hyperscalers such as AWS, Azure, and Google Cloud, intensify their push to develop offerings for building generative AI applications.

Rao’s exit comes at a time when Databricks is aggressively trying to expand its offerings inside the Data Intelligence Platform, mainly with Lakebase and Agent Bricks, thanks to the infusion of capital from this week’s $1 billion Series K funding round that saw its valuation surge past $100 billion.

As a result, Rao’s departure introduces uncertainty and raises questions about the company’s ability to sustain innovation velocity and technical leadership in a fiercely competitive market.

“Databricks is in a tricky spot with Naveen Rao stepping back. He was not just a figurehead, but deeply involved in shaping their AI vision, particularly after MosaicML,” said Robert Kramer, principal analyst at Moor Insights & Strategy.

“Rao’s absence may slow the pace of new innovation slightly, at least until leadership stabilizes. Internal teams can keep projects on track, but vision-driven leaps, like identifying the ‘next MosaicML’, may be harder without someone like Rao at the helm,” Kramer added.

Rao became a part of Databricks in 2023 after the data lakehouse provider acquired MosaicML, a company Rao co-founded, for $1.3 billion. During his tenure, Rao was instrumental in leading research for many Databricks products, including Dolly, DBRX, and Agent Bricks.

That leadership gap, the analyst warned, could give its rivals a convenient narrative to draw away customer attention.

“To counter any such narrative, Databricks needs to prove quickly that AI remains central to its Data Intelligence Platform and not just a layer on top. If they falter, rivals, specifically, hyperscalers, will use their speed and bundled services to lure customers,” Kramer said.

And rivals such as Snowflake are not sitting idle either. While Snowflake has continued to add features that rival most of Databricks’ AI and ML offerings, others such as Teradata and Cloudera are using strategies such as repositioning with AI factories and leaning into open standards such as Iceberg and the Model Context Protocol (MCP) to strengthen their AI approaches.

However, The Futurum Group’s lead for data intelligence and analytics, Bradley Shimmin, unlike Kramer, doesn’t foresee trouble for Databricks after Rao’s departure.

The AI market has shifted from building frontier models to integrating them, and technology vendors now compete by how well they apply these models, not by owning them, Shimmin said, pointing out that MosaicML’s contribution is passé.

Further, the analyst believes that Databricks will not lose ground to rivals like Snowflake or Teradata, as “the company already enjoys a comfortable lead, technologically speaking, in both building and running AI.”

No immediate successor

While analysts remain divided over the impact of Rao’s departure, the company is yet to name his successor despite the role of head of AI being central to its future product roadmap.

An email sent to Databricks specifically asking about succession did not elicit a response.

However, Kramer said that the company is more likely to rely on internal leaders who already know the platform, rather than rushing into an external hire.

“This approach helps maintain continuity but also risks leaving a gap in outward-facing thought leadership. External recruitment could happen down the line, but in the short term, it looks like they’ll tap existing product and research teams to carry forward Rao’s priorities,” Kramer said.

Offering a different view, Shimmin said that Databricks might not immediately feel the vacuum left by Rao, and can rely on CEO Ali Ghodsi and CTO Matei Zaharia.

After all, he said, “you’ve got two technology-first executives with steady hands on the steering wheel. With Matei in particular, you’ve got someone who literally created and open-sourced much of the technology upon which Databricks is built, not just Apache Spark, but also MLflow, and Delta Lake.”

Another fork in the road for Databricks?

Rao’s departure, according to Kramer, also presents Databricks with a critical choice: focus more on execution, making steady progress on the AI capabilities already underway, or chase the next big bet.

For Databricks, the next big bet could be innovating on balancing the cost and efficiency of its offerings, Kramer said, adding that one way to achieve that would be specialized hardware for AI.

Targeted hardware for AI can bring down the cost of training models or running complex queries to generate insights.

Databricks is also investing in Rao’s startup, CEO Ali Ghodsi wrote on LinkedIn, and confirmed that, as Rao had already hinted in a post, it would focus on the AI hardware space.

Rao, when asked directly about his startup, said that he would provide more details next week.

For now, especially after Rao’s departure, Databricks may have to lean more on partnerships, although, given the company’s history of acquisitions and all the tell-tale signs, Rao and his new startup may in the future become part of the company again.

Kotlin 2.2.20 has been released, with the latest version of the concise, multiplatform, “pragmatic” programming language bringing its WebAssembly-compilation component, Kotlin/Wasm, into beta.

JetBrains announced Kotlin 2.2.20 release on September 10. The release includes a beta version of the Kotlin/Wasm tool for compiling Kotlin code into WebAssembly (Wasm), with improvements to exception handling in JavaScript interop, NPM dependency management, browser debugging support, and a new shared source set for js and wasmJs targets, JetBrains said.

In explaining why a stable release of Kotlin includes a feature in a beta stage, JetBrains said that while core components such as the standard library are considered stable and production-ready, other components, such as Kotlin/Wasm, may still be in a pre-stable stage, such as beta. This is part of an approach to provide early access to features for feedback while clearly marking their stability level, the company noted.

Also with Kotlin 2.2.20, Kotlin Multiplatform now makes Swift export available by default, provides stable cross-platform compilation for Kotlin libraries, and introduces a new approach to declaring common dependencies, letting developers declare common dependencies in the kotlin {} block by using a top-level dependencies {} block in projects that use Gradle 8.8 or higher.

For the Kotlin language itself, Kotlin 2.2.20 improves overload resolution when passing lambdas to overloads with suspend function types. Kotlin/Native, for compiling Kotlin code to native binaries, now has support for stack canaries and smaller release binaries. Additionally, Kotlin/JS, for translating Kotlin code into JavaScript, now compiles Long values into JavaScript BigInt.

The Kotlin plugin supporting Kotlin 2.2.20 is bundled in the latest versions of the IntelliJ IDEA and Android Studio IDEs. With Kotlin 2.2.20, developers also can try out upcoming language features planned for Kotlin 2.3.0, including improved overload resolution when passing lambdas to overloads with suspend function types, and support for return statements in expression bodies with explicit return types.

Instructions for installing Kotlin 2.2.20 can be found at blog.jetbrains.com.

Enterprise AI tends to default to large language models (LLMs), overlooking small language models (SLMs). But bigger isn’t always better. Often, a smaller, more specialized model can do the work faster and more efficiently.

What complicates things is that neither an LLM nor an SLM alone may give you everything you need, especially in complex enterprise environments. In both cases, structure is essential. That’s where knowledge graphs come in. Knowledge graphs add the context and connections that make these models truly useful.

The value of SLM thinking in enterprise AI

Let’s start with SLMs versus LLMs. Developers were already warming to small language models, but most of the discussion has focused on technical or security advantages. In reality, for many enterprise use cases, smaller, domain-specific models often deliver faster, more relevant results than general-purpose LLMs.

Why? Because most business problems are narrow by nature. You don’t need a model that has read TS Eliot or that can plan your next holiday. You need a model that understands your lead times, logistics constraints, and supplier risk. That’s what makes the output meaningful—not intelligence in general, but intelligence grounded in your context.

Reasoning models, by the way, already work this way: quietly and efficiently. Even cutting-edge systems like DeepSeek use a “mixture of experts” approach, calling on specialized internal components (like a math engine) to solve targeted problems, rather than activating the entire neural network every time.

This modular strategy mirrors how enterprises actually operate. Instead of relying on one monolithic model, you deploy multiple small language models, each focused on a specific domain, such as finance, ops, or customer service. Their outputs are then synthesized by a generalist coordinator model, possibly routed through an AI agent that knows which “expert” to call on when. The result is a flexible, efficient architecture that aligns with real-world organizational structures.

Which, of course, is how humans solve problems too. A physicist might struggle with a tax question, while you or I could give a passable, but vague, answer. Combine the two and you get both precision and coverage. AI works the same way. It performs best when there are clear boundaries of expertise and smart systems for delegation.

Just like in e-commerce or IT architecture, organizations are increasingly finding success with best-of-breed strategies, using the right tool for the right job and connecting them through orchestrated workflows. I contend that AI follows a similar path, moving from proof-of-concept to practical value by embracing this modular, integrated approach.

Plus, SLMs aren’t just cheaper than larger models, they can also outperform them. Take Microsoft’s Phi-2, a compact model trained on high-quality math and code data. Phi-2 outperforms much larger models, sometimes dramatically so, but only within its specialized domain. Its strength comes not from size, but from the focus and precision of its training data.

The key challenge with massive models trained on diverse data sets is that adding new data can degrade previously accurate outputs, as shifting weights alter earlier responses. SLMs avoid this issue by design, maintaining their narrow, focused expertise.

Making models work together optimally

But specialization brings its own challenge: orchestration. Managing multiple small models, and perhaps one or two LLMs, requires precise intent recognition and smart routing. When a user asks a question, the system must correctly interpret it and send it to the right model to deliver a reliable answer.

Because even the most advanced LLMs lack true meta-awareness, this routing logic is often hard-coded by data scientists, making full automation of task delegation tricky, while at the same time adding to the cost of the solution. In response, many enterprises are adopting a hybrid approach. They start with a general-purpose LLM, identify where it falls short, and then deploy SLMs to fill those gaps.

A broader issue is the dominance of generative AI in public discourse, which has somewhat overshadowed decades of valuable non-generative tools. As teams improve at tackling real enterprise-scale data problems, we’re likely to see a shift toward a more balanced, pragmatic toolbox—one that blends statistical models, optimization techniques, structured data, and specialized LLMs or SLMs, depending on the task.

In many ways, we’ve been here before. It all echoes the “feature engineering” era of machine learning when success didn’t come from a single breakthrough, but from carefully crafting workflows, tuning components, and picking the right technique for each challenge. It wasn’t glamorous, but it worked. And that’s where I believe we’re heading again: toward a more mature, layered approach to AI. Ideally, one with less hype, more integration, and a renewed focus on combining what works to solve real business problems, and without getting too caught up in the trend lines.

The need for other tools

After all, success doesn’t come from a single model. Just as you wouldn’t run a bank on a database alone, you can’t build enterprise AI on raw intelligence in isolation. You need an orchestration layer: search, retrieval, validation, routing, reasoning, and more.

And I believe graph technology is key to making any version of AI actually work. There’s growing momentum around pairing structured graph data with AI systems, where graphs act like domain-specific “textbooks,” boosting accuracy and dramatically reducing hallucinations.

Crucially, graphs provide a structure that allows non-technical users to query complex data in intuitive ways, without needing to understand graph theory. LLMs often struggle with long context windows, and simply injecting more data rarely solves the problem. But graphs excel at grouping related information and surfacing insights across multiple levels of abstraction. Graphs enable better answers to high-impact business questions, like “What are the key themes in my business?” or “Where are my biggest operational challenges?”

Techniques like retrieval-augmented generation (RAG), intelligent search, and graph-based logic are what make AI outputs usable, trustworthy, and truly aligned to task. A knowledge graph that draws on the latest advances, such as vector search, dynamic algorithms, and especially graph-based RAG (or GraphRAG), can feed context with unprecedented precision.

The strongest case for the future of generative AI? Focused small language models, continuously enriched by a living knowledge graph. Yes, SLMs are still early-stage. The tools are immature, infrastructure is catching up, and they don’t yet offer the plug-and-play simplicity of something like an OpenAI API. But momentum is building, particularly in regulated sectors like law enforcement where vendors with deep domain expertise are already driving meaningful automation with SLMs. As the ecosystem matures, others will follow.

What we’re heading toward is a more integrated AI stack where graphs, SLMs, and classic AI techniques combine into systems that are not just powerful, but purposeful. Just as no one talks about the AI in a calculator, the best AI may soon become an invisible but indispensable part of tools that simply work.
