Summary
On June 30, 2026 GitHub and JetBrains made GitHub Copilot a first-class option in the JetBrains AI Assistant agent picker. Developers can select Copilot as the active agent directly in the AI chat, choose among supported Copilot models, tune reasoning depth, and have Copilot propose changes, run commands, perform Git operations, and manage pull requests and issues without leaving the IDE.
What changed
JetBrains AI Assistant added GitHub Copilot to its agent picker as a native agent, letting users pick Copilot models and reasoning depth in-chat and delegate multistep coding, Git, and PR/issue work; the integration requires an active GitHub Copilot subscription and, per Microsoft, is moving to Copilot CLI as the default agent harness.
Why it matters
Making Copilot a selectable agent inside a rival IDE's assistant turns the agent picker into the new competitive battleground, decoupling the coding agent from its home editor and pressuring tools to interoperate rather than lock users in.
