OpenAI had a year of high-profile departures.
Over the summer, the ChatGPT creator lost at least seven researchers and scientists to Meta’s billion-dollar effort to beef up its AI team at its Superintelligence Lab.
This came after the company saw an exodus of top executives in 2024 amid a restructuring effort, including chief technology officer Mira Murati, chief research officer Bob McGrew, and vice president of research Barret Zoph.
CEO Sam Altman is now one of only two active remaining members of the company’s original 11-person founding team.
Here’s a running list of researchers and executives OpenAI has lost this year and where they’ve ended up.
