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."

Billionaire Elon Musk announced that Grok, a generative artificial intelligence chatbot, will be available in Tesla vehicles starting next week "at the latest."

Grok 4 is xAI’s most advanced model yet, but early praise is clashing with old scandals and fresh tests of its limits.
