This is the smartest AI in the world,” Musk said. He did not mention the chatbot’s viral posts praising Hitler and calling itself “MechaHitler.”

AI has officially lunched Grok 4 during a livestream with Elon Musk, who called it the "smartest AI in the world." He said that if you make the Grok 4 take the SATs and the GREs, it would get near perfect results every time and can answer questions it's never seen before.

Elon Musk's AI chatbot, Grok, made numerous antisemitic remarks, including praising Hitler's leadership, in a series of posts on X. Before University of Virginia President James Ryan resigned, the Justice Department pressured him over U.Va's handling of an alleged antisemitic hate crime.
