Sam Altman, CEO of OpenAI, attends the Asia-Pacific Economic Cooperation (APEC) CEO Summit in San Francisco, California, U.S. November 16, 2023.

On Friday, the board of OpenAI, the buzzy AI company behind viral chatbot ChatGPT, suddenly and publicly ousted its CEO Sam Altman. The announcement came one day after he appeared publicly on behalf of his company at Thursday's APEC CEO Summit.

OpenAI's board said it conducted "a deliberative review process" and that Altman "was not consistently candid in his communications with the board, hindering its ability to exercise its responsibilities."
