JetBrains AI

I was testing my agent built on Koog, JetBrains' open-source framework for building AI agents in Kotlin. I fed it a task from SWE-bench-Verified, a real-world GitHub issue that tests whether AI can actually write code. For the first 100 messages, everything looked promising. The agent methodicall…

At AI Summit London 2025, Kris Kang, Head of Product for AI at JetBrains, gave a talk that questioned a common belief in AI development: that bigger means better.

AI is no longer a distant idea. It’s already here and changing how we build software. As it advances, new questions emerge about its impact. 

We’ve just released Koog 0.3.0, which comes with many updates that make building, running, and managing intelligent agents easier. This version focuses on durability, speed, observability, and smoother integration with real-world systems. If you’ve been exploring how to develop your own intellige…

In May, 145 JetBrains employees from across teams and time zones paused their regular work to participate in a 48-hour AI hackathon. With support from Google Cloud, the participants built a total of 41 prototypes from scratch. Some were practical, others experimental, but all explored how AI could change how developers work.

As AI tools continue to advance and become bigger parts of our lives, it is important to think critically about AI interactions. At JetBrains, some of our research teams study this, with a particular interest in enhancing these interactions in code-related tasks. In this post we will look at how our teams applied insights from a leading theory on motivation, Self-Determination Theory, to empirical results, and identified areas for actionable improvement.

JetBrains Mellum – our open, focused LLM specialized on code completion – is now available to run as a containerized microservice on NVIDIA AI Factories.

In AI-enabled IDEs, code completion quality heavily depends on how well the IDE understands the surrounding code – the context. That context is everything, and we want your help to find the best way to collect it.

It often feels like AI is ubiquitous these days. From helping with research to creating a joke, AI seems able to do everything for us. The public response and general opinions about AI are mixed. Some see the negative aspects of AI and frequently wonder, “Will AI take over my job?”, “Could AI steal …

We’ve got some exciting news for the Kotlin Community! At this year’s KotlinConf, we’re introducing Koog, an innovative, open-source agentic framework that empowers developers to build AI agents within the JVM ecosystem using a modern Kotlin DSL. We designed Koog to provide developers with the tools…
