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."

AI chatbot Grok, which is produced by Elon Musk’s artificial intelligence company xAI, issued an apology Saturday after it made numerous antisemitic posts on X this week following an update
