Microsoft's VP of GenAI research to join OpenAI

Microsoft's GenAI research VP, Sebastien Bubeck, is joining OpenAI. While his role at OpenAI is unknown, Microsoft's spokesperson mentioned continuing collaboration. Most of his coauthors on the Phi LLMs project remain at Microsoft. This follows recent high-profile departures from OpenAI, including ex-CTO Mira Murati, but CEO Sam Altman denies any connection to company restructuring.
