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.”

Will Stancil says he is "considering" suing Elon Musk's X after Grok shared a hypothetical plan for breaking into his home and raping him

Linda Yaccarino is stepping down as CEO of X after two years leading Elon Musk’s social media company. Yaccarino’s departure comes one day after the company’s Grok chatbot began pushing antisemitic tropes in responses to users. It’s not clear that the events were connected.

On Tuesday July 8, X (née Twitter) was forced to switch off the social media platform’s in-built AI, Grok, after it declared itself to be a robot version of Hitler, spewing antisemitic hate and racist conspiracy theories. This followed X owner Elon Musk’s declaration over the weekend that he was insisting Grok be less “politically correct.”
