OpenAI hires Microsoft generative AI research lead

OpenAI has recruited Sebastian Bubeck, Microsoft’s former VP of generative AI research.

Bubeck, known for his work on Microsoft’s Phi models—compact language and vision models designed to run AI applications powerfully on edge devices—brings valuable expertise as AI moves toward more efficient, on-device models.

His departure, first reported by The Information and confirmed by Reuters, signals a potential shift in focus for OpenAI, which has so far been more associated with large centralized models like GPT-4.

Bubeck's exact role at OpenAI remains undisclosed.
