Microsoft Reshuffles AI Leadership: Suleyman to Focus on In-House LLMs
Microsoft has announced a major reorganization of its artificial intelligence division, placing Mustafa Suleyman in charge of frontier model development and removing him from leadership of the Copilot business. Jacob Andreou, former Senior Vice President at Snap, will take over as Executive Vice President of the entire Copilot unit, including Microsoft 365 Copilot, and will report directly to CEO Satya Nadella. The restructure comes as Microsoft's Copilot lags behind rivals: the app records about 150 million monthly active users, while Google Gemini has 750 million and OpenAI's ChatGPT roughly 900 million weekly active users. Only 15 million of over 450 million commercial customers currently use the paid Microsoft 365 Copilot service. Microsoft, which holds a 27 percent stake in OpenAI, aims to reduce its dependency on the ChatGPT maker and strengthen its own in-house LLM capabilities.
The reshuffle repositions Microsoft's AI strategy around independent frontier model development, reducing reliance on OpenAI and intensifying competition among LLM providers whose models increasingly power enterprise and advertising technology.
