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."

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.”

Antisemitic outbursts from the chatbot promoted by Elon Musk shows how AI companies often face minimal consequences when their projects go rogue.
