In the previous article, we saw how to build a basic coding agent with list, read, write, and edit capabilities. Today, we'll dive into how to extend the agents’ capabilities by creating additional tools within the Koog framework. As an example, we’ll be building an ExecuteShellCommandTool, teaching…

The latest AI model from Google, Gemini 3 Pro, is now live in JetBrains IDEs. From day one, it powers AI Chat and Junie, our coding agent, giving you smarter reasoning, stronger instruction following, and seamless integration into your workflow. https://youtu.be/sGcmLabwUxc What’s new Gem…

Building agents is weird. You're not writing code that does things. You're writing code that gives an LLM the ability to do things, and the LLM decides what to do. What is an agent? An agent is an LLM that calls your functions in a loop until it decides the task is complete. That shift takes s…

At JetBrains, we've always believed in giving developers the best possible tools to enhance productivity and creativity. Recently, you've shared important feedback about AI usage limits, transparency, and the freedom to choose which AI providers you use. We heard you loud and clear. That’s why we…

Every developer recognises the trade-off. You can take the shortcut that delivers today but breaks tomorrow, or choose the slower approach that earns lasting confidence.

At JetBrains, we've spent 25 years building tools for developers. Over the past two years, we've seen that AI isn't just changing how developers write code – it's beginning to reshape the entire process of product development. Not only is AI making developers more productive, helping with everyth…

We recently released Koog 0.5.0, introducing full Agent2Agent (A2A) protocol support, which makes it easier than ever to build systems of interconnected AI agents in Kotlin. But A2A is just the beginning. Koog 0.5.0 brings a host of improvements that make agents more persistent, tools smarter, an…

JetBrains is collaborating with Zed on the Agent Client Protocol (ACP) – an open protocol that lets AI coding agents work inside editors.

If you’ve ever tried building a system of multiple AI agents, you’ve probably run into the problem. It starts simple enough: you’ve got one agent writing blog posts, another proofreading them, and maybe a third suggesting or generating images. Individually, they’re effective. But getting them to work together? That's where things might start falling apart.

The new Claude Agent is now seamlessly integrated into JetBrains IDEs via the AI chat and included in the JetBrains AI subscription.

In our last post, we introduced our talented intern cohort from our AI4SE research partnership with TU Delft. In this post, we're excited to spotlight the next chapter in their journey: their evolution from interns to full-time members of our tech team. These individuals didn't just stand by and observe: they immersed themselves in real projects, tackling complex challenges with technologies at the core of our business.

Starting August 25, 2025, we’re rolling out a new AI quota model that makes AI subscriptions easier to understand and manage, while also letting you seamlessly extend your usage beyond your included quota .
