A group of investors led by Elon Musk has said it is offering more than $97bn to buy OpenAI, escalating a legal dispute with the artificial intelligence company that Mr Musk helped found.

Mr Musk and his own AI start-up, xAI, and a consortium of investment firms say they want to buy the ChatGPT-maker and revert it back to its original charitable mission as a non-profit research lab, according to Musk lawyer Marc Toberoff.
