OpenAI CEO and co-founder Sam Altman has been reinstated to the firm's board of directors following an outside investigation into the turmoil that led the company to abruptly fire and rehire him in November.

OpenAI said the investigation by the law firm WilmerHale concluded that Altman's ouster had been a consequence of a breakdown in the relationship and loss of trust" between Altman and the prior board and that the CEO's conduct did not mandate removal".
