Microsoft chief says 'no OpenAI' without tech giant's involvement

The boss of Microsoft has said there is "no OpenAI" without his company's involvement, as he revealed the American tech behemoth was not consulted about the sacking of Sam Altman. Satya Nadella said Microsoft, OpenAI's biggest investor, was not contacted by OpenAI board members before they sacked Altman as chief executive on Friday. Speaking to the tech journalist Kara Swisher on her podcast, he said: "It's not even the money and the capital. I mean, here's a simple way to think about this. Someone's got to think about why? There is no OpenAI without, sort of, Microsoft leaning in, in a deep way, to partner with this company on their mission."
