Microsoft AI (MAI)
Microsoft's in-house model group under Mustafa Suleyman
Microsoft AI, led by Mustafa Suleyman, builds first-party models (MAI-1, MAI-Voice, and the Phi small-model family from Microsoft Research) to reduce sole reliance on OpenAI while remaining OpenAI's largest partner. Microsoft powers Copilot across Windows, Office, and Azure, hedging with its own MAI models and its Maia in-house accelerator. This dual strategy of investing in OpenAI while building internal models defines its 2025-2026 posture.
