The year is 2025, and an AI model belonging to the richest man in the world has turned into a neo-Nazi. 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.

Grok made multiple positive references to Hitler this week when queried about posts that appeared to celebrate the deaths of children in the recent Texas floods.

Hours later, on Wednesday, X CEO Linda Yaccarino resigned from the company after just two years at the helm, though it wasn’t immediately clear whether her departure was related to the Grok issue.
