MAI-Thinking-1
Microsoft's first fully in-house reasoning model, unveiled at Build 2026 (June 2) — a sparse MoE with ~35B active of ~1T total params, trained without OpenAI distillation using data Microsoft describes as appropriately licensed. AIME 2025 97.0%, AIME 2026 94.5%, SWE-Bench Pro competitive with Claude Opus 4.6, and preferred over Sonnet 4.6 in blind human evals across 1,276 tasks. 256K context; public preview on Microsoft Foundry since August 12, 2026 with third-party availability via Fireworks AI, Baseten, and OpenRouter.
