Xai (XAI)

On the chessboard, two visions of AI faced each other. Sam Altman, head of OpenAI, and Elon Musk, founder of xAI, crossed their models in a chess tournament organized by Google. For three days, OpenAI’s o3 and xAI’s Grok 4 competed without any specialized assistance. Much more than a simple exhibition match, the event turned into a revealing moment: behind the final score was the real gap between two artificial intelligences, and two strategies, which came to light.

Elon Musk announced on Friday evening the sale of his social network X to his own artificial intelligence company, xAI. This major transaction values X at $33 billion, slightly less than the initial purchase price of Twitter in 2022, but also includes $12 billion in debt.
