Revolution at the top of OpenAI, the non-profit that controls ChatGPT. The CEO Sam Altman leaves and the chief technology officer is appointed in his place on an interim basis Mira Murati. OpenAI states this in a note, in which it specifies that Altman is also leaving the board of directors. His exit is linked to a review requested by the board of directors and which concluded that Altman was not always “candid in his communications with the board of directors, hindering his ability to carry out his responsibilities”. The board of directors does not have confidence in his ability to continue to lead OpenAI,” it said in a statement.
