On November 17 2023, the OpenAI board of directors fired CEO Sam Altman without warning, triggering a five-day crisis in which nearly 700 employees threatened mass resignation and Microsoft pressured the board to reinstate him. Altman was reinstated on November 21 with a reconstituted board. Multiple framings of the event circulate as conspiracy claims: an "AI safety coup" by board members who believed Altman was recklessly commercialising dangerous technology; a "Microsoft-orchestrated power grab" to install compliant leadership; and allegations that board member Helen Toner's academic paper criticising OpenAI was the proximate trigger. Evidence partially supports the safety-framing; the Microsoft-coup framing is more contested; Toner's paper role is documented but disputed as decisive.
