Sam Altman set to return as CEO of OpenAI

Sam Altman is set to make a return as chief executive of OpenAI after the ChatGPT developer said it had "reached an agreement in principle" for his reinstatement. The San Francisco-based company made the announcement after days of corporate drama in the wake of Altman's surprise sacking on Friday. Nearly all of OpenAI's 750-strong workforce had threatened to quit unless the board overseeing the business brought back Altman and then quit immediately afterwards. As part of the agreement reached overnight, the deal includes a new-look board led by Bret Taylor, the former co-CEO of software firm Salesforce. It will include Larry Summers, the former US treasury secretary, and Adam D'Angelo, the tech entrepreneur and current board member who played a role in Altman's firing.
