Sam Altman, the CEO and co-founder of OpenAI, said his company is not for sale, after Elon Musk and his investors on Monday offered to buy OpenAI’s for-profit assets for $97.4 billion. Altman responded to the bid by posting on X: “no thank you but we will buy twitter for $9.74 billion if you want.” Altman has been attempting to disentangle OpenAI, which developed ChatGPT, from its nonprofit status and board. OpenAI was co-founded by Musk in 2015, but he left in 2019.

Vice President JD Vance, who is in Paris for the AI Action Summit — as is Sam Altman — warned other countries against regulating U.S. tech and blasted the EU’s ongoing efforts to regulate AI, social media and tech monopolies.
