GitHub Copilot will run Microsoft's MAI Code 1.1 Flash locally and auto-route between your PC and the cloud

Announced Oct 7 and due by end of October in Copilot CLI, the Copilot app, and VS Code, a 53GB quantized build of the 137B-parameter (6.8B active) MoE scores 70.8% on SWE-Bench Verified vs 72.6% for the cloud version, with Auto mode picking local or cloud per task or you selecting it via Windows ML or any OpenAI-compatible local endpoint. Microsoft's reference machine is an RTX Spark Surface Laptop Ultra with 128GB unified memory (75.5GB peak at 256K context), and local inference alone doesn't make a session offline.
