The ousted leader of ChatGPT maker OpenAI is returning to the company that fired him just days ago. The move culminates a short but chaotic power struggle that shocked the tech industry and underscored the conflicts around how to safely build artificial intelligence. San Francisco-based OpenAI said late Tuesday that it’s also bringing on a new board of directors that replaces the one that fired Altman as CEO on Friday. Lack of transparency surrounding Altman's firing led to a weekend of internal conflict and growing outside pressure from the startup’s investors. An expert says the turmoil “shows how fragile the AI ecosystem is right now, including addressing AI’s risks.”
