Greg Brockman, co-founder of OpenAI, has officially returned to the company after a three-month leave of absence, bringing a key figure back to the organization amid a string of leadership departures.

In an internal memo shared with staff on Tuesday, Brockman confirmed his return, noting that he had been working closely with OpenAI’s CEO Sam Altman to create a new role focused on addressing significant technical challenges. The company has since confirmed Brockman’s return to its leadership team.

Brockman’s return comes at a critical time for OpenAI, which has seen several high-profile exits in recent months. Among the departing figures are former Chief Technology Officer Mira Murati, co-founder John Schulman, and one of its leading safety researchers, Lilian Weng. With

Known to many within the company by his initials GDB, Brockman has been a central figure in OpenAI’s development, working closely with Altman, especially after Altman’s brief ousting as CEO last year. During that time, Brockman resigned in protest, only to return when Altman was reinstated.

Brockman had announced in August that he would be taking a sabbatical through the end of the year to "relax" for the first time since the company was founded in 2015. Now back at OpenAI, Brockman’s leadership will likely play a crucial role in navigating the company through its current challenges.
