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.

The unusual behavior of Grok 4, the AI model that Musk's company xAI released late Wednesday, has surprised some experts.
