## Summary

GitHub Copilot Fusion can now choose between supported on-device models and cloud models in GitHub Copilot CLI, the GitHub Copilot app, and Visual Studio Code. The opt-in experimental preview is set up differently per tool, with managed MAI Code 1.1 Flash download on supported Windows devices. Routing decisions are still made in the cloud, so local inference does not make a session offline.

## Why it matters

The post specifies which tools support the opt-in local routing preview, how Windows setup works, and why local inference does not make sessions offline.
