GitHub Copilot: Free Desktop App, JetBrains, Cost Controls

GitHub has launched three Copilot updates, significantly advancing autonomous AI coding. The new changes include a free desktop app, expanded reach into the JetBrains ecosystem, and new spending controls for administrators. Here's the thing: developers on the free tier can now run full agent sessions. JetBrains users can also now use Codex without changing editors. Enterprise cost centers can cap AI credit consumption. The standalone Copilot desktop app is now available on all Copilot plans, including free-tier accounts and GitHub Education licenses, across macOS, Windows, and Linux. This expansion is significant because the desktop app operates differently from an extension within an IDE. It treats each task as an isolated agent session, backed by its own git worktree, preventing file conflicts and context contamination when multiple tasks run in parallel. Developers can start sessions from GitHub issues, open pull requests, or plain-text prompts, with completed work flowing through existing team review requirements. This means more developers now have access to powerful AI coding tools.
