OpenAI co-founder and President Greg Brockman said he’s departing from the maker of generative artificial intelligence tools just hours after the board pushed out Chief Executive Officer Sam Altman. “We’ve been through tough and great times together, accomplishing so much despite all the reasons it should have been impossible,” Brockman wrote in a post on X. “But based on today’s news, I quit.”

“I’m super proud of what we’ve all built together since starting in my apartment 8 years ago,” Brockman wrote in a post on the social media site X.

Earlier, the company said it had dismissed CEO Sam Altman after a review found he was “not consistently candid in his communications” with the board of directors.

“The board no longer has confidence in his ability to continue leading OpenAI,” the company said. It added that Mira Murati, OpenAI’s chief technology officer, will take over as interim CEO effective immediately.

Following the news of his sacking, Altman took to X (formerly X) and said, “I loved my time at OpenAI. It was transformative for me personally, and hopefully the world a little bit. Most of all I loved working with such talented people. Will have more to say about what’s next later.”

After sacking Altman, OpenAI appointed CTO Mira Murati as the interim CEO. The company said that Murati had a “unique skill set” and would provide “a seamless transition while it conducts a formal search for a permanent CEO.”

OpenAI has emerged as one of the most powerful companies in artificial intelligence, in a new era in the mainstream for AI last November, when OpenAI released the wildly popular ChatGPT. The move pushed generative AI to the forefront of Silicon Valley, causing incumbents like Alphabet to beef up their own AI product development.
