Microsoft has hired the founders of tech firm Open AI, Sam Altman and Greg Brockman, to lead a new advanced AI research team.
In a move that shocked the tech world, last week Mr Altman was fired by the board of Open AI, who accused him of a "lack of candour".
Staff at Open AI have since called on the board to reinstate Sam Altman in a letter, warning that Microsoft has assured them that there are jobs for them if they want to join the company too.
Tech analyst Dan Ives spoke to Corin Dann.
