JetBrains Air vPublic Preview

JetBrains Air is an Agentic Development Environment (ADE) designed to orchestrate multiple AI agents simultaneously, allowing them to work on separate tasks within isolated environments. It enables developers to delegate coding work to models like Claude, Codex, Gemini, and Junie while maintaining oversight through an IDE-like interface.

Mellum2 v2.0

Mellum2 is a 12-billion-parameter AI model developed by JetBrains, designed to address challenges in production AI such as latency, throughput, and cost. It is specifically trained on natural language and code data, making it well-suited for tasks like routing, summarization, and intermediate reasoning in software engineering systems. Released under the Apache 2.0 license, Mellum2 offers a high-performance, cost-efficient alternative for AI infrastructure.

Junie in IDEs vGenerally Available

Junie in IDEs is an AI-powered coding agent developed by JetBrains, designed to autonomously plan and execute complex, multi-step actions directly within your workspace. Operating through a native IDE tool window and interactive editor tabs, it integrates seamlessly into JetBrains IDEs and Android Studio. Junie assists with tasks such as code generation, running tests, and adapting to project-specific guidelines, allowing developers to review structured plans and monitor progress side-by-side with their code.

Junie CLI vGenerally Available

Junie CLI is a terminal-first, AI-powered coding agent developed by JetBrains, designed to autonomously plan and execute complex, multi-step actions directly from the command line. It brings agentic capabilities—such as advanced plan generation, code execution, and project-aware code reviews—directly to your favorite terminal. Powered by the JetBrains Agent Communication Protocol (ACP), the CLI connects to your running JetBrains IDEs to leverage their native semantic indexes and test runners, while remaining portable enough to run asynchronously in CI/CD pipelines or remote environments.
