A group of investors led by Elon Musk is offering about $97.4 billion to buy the nonprofit behind OpenAI, escalating a dispute with the artificial intelligence company that Musk helped found a decade ago.

Musk and his own AI startup, xAI, and a consortium of investment firms want to take control of the ChatGPT maker and revert it to its original charitable mission as a nonprofit research lab, according to Musk’s attorney Marc Toberoff.

OpenAI co-founder and CEO Sam Altman quickly rejected the unsolicited bid on Musk’s social platform X, saying, “no thank you but we will buy Twitter for $9.74 billion if you want.”

Musk bought Twitter, now called X, for $44 billion in 2022. — Associated Press
