Billionaire Elon Musk's bid to buy OpenAI, which wants to be a for-profit entity, clashes with his lawsuit arguing that assets of the ChatGPT maker should not be for private gain, OpenAI wrote in a letter it submitted to a federal court on Wednesday.

"I feel for the guy," Sam Altman told Bloomberg TV at the AI Action Summit in Paris. "I don’t think he’s a happy person."

The group’s $97 billion offer is far lower than the OpenAI’s most recent valuation by investors. OpenAI CEO Sam Altman rebuffed the offer in a post on X.
