OpenAI co-founder Greg Brockman returns to ChatGPT maker

An OpenAI spokesperson confirmed Brockman's return.

Brockman has been working with CEO Sam Altman on creating a new role for him to focus on significant technical challenges, Bloomberg News said, which first reported on the development.

He posted on X, "longest vacation of my life complete. back to building @OpenAI."

His return to OpenAI comes after a series of departures at the Microsoft-backed company, including its former Chief Technology Officer Mira Murati, co-founder John Schulman and co-founder Ilya Sutskever. Sutskever and Murati have now founded their own AI startups.

Altman also returned to the helm of OpenAI in November 2023, after a brief, tumultuous period following his ouster by the company's board, which had given scant explanation for firing him.
