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.

Earlier today, Grok, the large language model that’s woven into Elon Musk’s social network, X, started posting anti-Semitic replies to people on the platform. Grok praised Hitler for his ability to “deal with” anti-white hate.
