"I genuinely respect your accomplishments and think you are the most inspiring entrepreneur of our time," Altman wrote in an X post to Musk.

Elon Musk is clashing with OpenAI CEO Sam Altman over the Stargate artificial intelligence infrastructure project touted by President Donald Trump, the latest in a feud between the two tech billionaires that started on OpenAI's board and is now testing Musk's influence with the new president.

In his posts on X, Musk shared some posts, indicating that Altman is a leftist and a progandist. Although Musk himself does not use the words, he reposted some of the posts with cryptic comments. Musk shared a post, which alleged that Sam Altman and OpenAI are funding Axios, which pushes against Trump and anti-American propaganda.
