The AI chatbot Grok, which is produced by Elon Musk’s xAI, wrote numerous antisemitic social media posts Tuesday after the artificial intelligence company released a revamped version of it over the weekend. The posts ranged from alleging "patterns" about Jewish people to praising Hitler.

Elon Musk has created a monster. Grok, the AI chatbot he commissioned for his social media platform, X, has been behaving strangely and terribly after its code was updated last week, spewing bigoted talking points when users ask for answers to questions about the world — and even floating Adolf Hitler as a figure worthy of admiration.

Elon Musk debuted Grok 4, saying it was capable of reasoning at "superhuman" levels and is "better than PhD level at everything."

Elon Musk's Grok AI chatbot blamed DOGE for Texas flood deaths and shared an antisemitic trope, days before Grok 4's release.
