Summary: Microsoft launched seven in-house MAI models at Build 2026 on 2026-06-02. MAI-Code-1-Flash is a 5B-parameter coding model integrated directly into GitHub Copilot and the VS Code model picker. MAI-Thinking-1 is a reasoning model. MAI Transcribe 1.5 supports 43 languages. Microsoft positions the MAI family as a path to reduce third-party model dependence.
Why it matters: MAI-Code-1-Flash ships inside GitHub Copilot's auto picker and delivers a 16-point SWE-Bench Pro lead over Claude Haiku 4.5 per Microsoft's internal benchmarks; developers using Copilot may see model-routing behavior change.
