According to TechFlow, on September 26, OpenAI founder and CEO Sam Altman announced on social media that major personnel changes were taking place at the company's top level. Chief Technology Officer Mira Murati, Chief Scientist Bob, and another executive Barret will leave. Altman said these decisions were independent and friendly.

Mark will take over as Senior Vice President of Research, leading the research team with Chief Scientist Jakub. Josh Achiam will become Head of Mission Alignment, Kevin and Srinivas will continue to lead the Applications team, and Matt Knight will become Chief Information Security Officer.

Altman stressed that while the move was abrupt, the leadership changes were a natural result of the company’s rapid growth. He plans to refocus efforts on the technology and product aspects of the company and will discuss the changes further at the all-hands meeting.
