Elon Musk on Wednesday unveiled Grok 4, a new version of his X platform's AI chatbot. The update comes a day after the bot posted antisemitic content on the social media network. Musk introduced the new model in a livestream on X late Wednesday, calling Grok 4 "the smartest AI in the world."

Elon Musk's new AI chatbot, Grok 4, is raising eyebrows for its unusual behavior. The chatbot, released Wednesday by Musk's company xAI, sometimes searches Musk's views online before answering questions.

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.”

Elon Musk's xAI faced internal backlash after Grok's antisemitic posts. Workers demanded answers — and one said they would quit.

A former professor and the founder of his own AI company, Howard noticed that if he asked Grok about the Israeli-Palestinian conflict, the chatbot seemed to cross-check Elon’s tweets before regurgitating an answer.

Grok 4 has a favorite source on some hot-topic issues, citing Elon Musk's opinions without being instructed to do so.
