(Reuters) - Sam Altman is rejoining the board of ChatGPT-maker OpenAI along with three new directors, as the startup tries to move past his sudden ouster in November that had shocked the tech industry.

Altman had returned as CEO of OpenAI just four days after his firing with a new board made up of Quora CEO Adam D'Angelo, former U.S. Treasury Secretary Larry Summers and former co-CEO of Salesforce Bret Taylor.
