At the center of this release is JetBrains Air – a new layer for agentic development. It lets you run, track, and verify multi-agent workflows directly inside your IDE, with code intelligence keeping agents on track and complete review tools in your hands. This release also brings workspaces that adapt terminals and consoles to individual subprojects, initial support for Python 3.15 lazy imports, interactive FastAPI dependency graphs, and deeper Pydantic inspections, and so much more.

JetBrains Air in PyCharm – One place to run your agents and verify their work As of this release, JetBrains IDEs ship with Air , a new layer for agentic development. Work with the coding agents of your choice, and run, track, and verify multi-agent workflows inside your IDE, where code intelligence helps agents make fewer wrong turns and gives you the tools to review every change before it ships. Your agents, your models, your subscriptions – with Junie Lite for free Air works with Claude Agent, Codex, Gemini, GitHub Copilot, Junie, OpenCode, and other ACP-compatible agents . It detects the agents already installed on your machine so you can connect them in a click, and you can add more from the agent registry. Your existing setup carries over, too: provider subscriptions, API keys, and even a custom base URL all work, with no JetBrains AI subscription required. Run Claude Agent on your Claude subscription in the terminal or in a full-screen IDE tab, use other agent subscriptions in the chat or terminal, and switch between subscriptions at any moment, even mid-session. Air includes free AI with the Junie Lite configuration, so you can use an agent without a subscription. You only need a JetBrains Account.
