MAI-Code-1-Flash
MAI-Code-1-Flash is Microsoft AI’s small active-parameter coding model, deployed in GitHub Copilot for everyday developer work. It was trained together with the production Copilot harness to handle repository questions, refactoring, multi-turn code changes, and adaptive reasoning. Microsoft reports five billion active parameters but has not disclosed the full architecture or total size. The model remains proprietary; access in a developer product is distinct from downloadable weights or a generally available independent API.
