Murati is the latest high-level exec to depart OpenAI in recent months. Sutskever and former safety leader Jan Leike announced their departures in May, and co-founder John Schulman said last month that he was leaving to join rival Anthropic. Meanwhile, OpenAI’s president, Greg Brockman, is on extended leave through the end of the year.

OpenAI Chief Technology Officer Mira Murati — who has been instrumental in the development of ChatGPT and the artificial intelligence image generator Dall-E — said Wednesday she is leaving the company.
