Sam Altman and Greg Brockman, former CEO and President of OpenAI, express shock and sadness after being fired by the board and are still seeking answers. Altman was informed of his termination in a board meeting, while Brockman learned separately that he was removed from the board but could retain his role in the company. Internal conflicts over AI development safety and commercialization may have contributed to Altman's ouster, with employees expressing concerns about the company's direction.
