Microsoft introduced MAI-Thinking-1, its first reasoning language model built without distillation from third-party models, comparable in size to Claude Sonnet 4.6. The model uses a mixture-of-experts architecture (1T total / 35B active parameters), was pretrained on 30 trillion tokens of primarily licensed human-generated data, and trained via reinforcement learning across specialist models for STEM, coding, and safety. It scored 97.0% on AIME 2025, placing third behind Claude Opus 4.6 and ahead of DeepSeek V3.2, and is available in private preview via Microsoft Foundry. The release marks a strategic shift as Microsoft moves to reduce dependence on OpenAI models following a renegotiated partnership in April 2026.
