JetBrains AI

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…

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 .

Instantly deploy a trusted, transparent code completion model without additional fees.

En deux mots : Depuis le 25 août 2025, nous déployons un nouveau modèle de quotas d'IA qui simplifie la compréhension et la gestion des abonnements à l'IA, et vous permet d'étendre facilement votre utilisation au-delà de votre quota inclus grâce à une tarification transparente en devises réelles. Le…

In a short series of posts, we will tell you about four recent graduates who were part of our AI for Software Engineering (AI4SE) research partnership with Delft University of Technology (TU Delft). Having recently completed their MSc thesis work as interns here at JetBrains, they are now starting full-time positions with us. The first post will introduce you to them and their experiences at JetBrains so far, and the second will go deeper into their experiences and new roles.

Featuring Langfuse and W&B Weave Support, Ktor Integration, Native Structured Output, iOS Target, GPT-5, and More. Koog 0.3.0 was about making agents smarter and persistent. Koog 0.4.0 is about making them observable, seamlessly deployable in your stack, and more predictable in their outputs …
