Brockman, who helped found OpenAI alongside Altman, said in a post on X that he was quitting. The company had said earlier in the day that he would step down as chair of the board but remain as president, reporting to the CEO.
“I’m super proud of what we’ve all built together since starting in my apartment 8 years ago,” Brockman wrote. “We’ve been through tough & great times together, accomplishing so much despite all the reasons it should have been impossible. But based on today’s news, I quit,” he said.
“Genuinely wishing you all nothing but the best,” Brockman wrote in his post. “I continue to believe in the mission of creating safe (artificial general intelligence) that benefits all of humanity.”
Earlier, the OpenAI board said was parting ways with Altman, also a co-founder and one of the most prominent figures in the AI world, after losing confidence in him as a leader.
