A consortium of investors led by Tesla chief executive Elon Musk has made a $97.4bn bid to buy ChatGPT maker OpenAI. The purpose of this bid, according to Musk's attorney Marc Toberoff, is to prevent OpenAI from pivoting from a nonprofit entity to a for-profit. The group of investors wants to retake control of the tech firm and revert it to its original charitable mission as a nonprofit research lab.
