ChatGPT creator OpenAI announced November 21, 2023, that Altman would return as its CEO, days after his shock dismissal plunged the pioneering artificial intelligence firm into crisis. Hundreds of OpenAI staff threatened to quit following Altman's sacking on November 17, demanding in a letter released to the media the resignation of the board, as speculation swirled about the future of the company.
