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."

The ‘maximally truth-seeking’ chatbot checks Musk’s stance on topics around Israel and Palestine, abortion, and immigration.

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.

Elon Musk says Grok AI has been upgraded to focus on "facts over feelings," but its sharp political and cultural replies are drawing criticism.
