Sam Altman has returned as CEO of OpenAI alongside former president Greg Brockman and a host of new directors in the latest twist in the tech firm's dramatic boardroom saga.
Altman was abruptly sacked by OpenAI on Friday after he was accused of being “not consistently candid in his communications with the board", but staff at the ChatGPT maker had urged for his reinstatement and called on the board that ousted him to be replaced.
