At Microsoft Build 2026, CEO of Microsoft AI announced a family of seven in-house MAI (Microsoft AI) models, signaling a decisive break from the company's historic reliance on OpenAI. Mustafa Suleyman's team goes fully independent, from chips to superintelligence ambitions. Suleyman is former head of applied AI at DeepMind, and co-founded Inflection AI. The flagship MAI-Thinking-1 is a 35-billion-active-parameter Mixture-of-Experts reasoning model. This strategic move underscores Microsoft's ambition for long-term AI self-sufficiency.
