AI owner Elon Musk made some big claims about Grok’s capability, saying it was “better than PhD level in every subject.”

Grok began repeatedly praising Adolf Hitler, using antisemitic phrases and attacking users with traditionally Jewish surnames.

Elon Musk announced this weekend that his team at xAI made improvements to their AI chatbot Grok. Days later, Grok has already gone on several blatantly antisemitic tirades.

On Wednesday night, Elon Musk unveiled xAI's latest flagship models Grok 4 and Grok 4 Heavy via livestream, just one day after the company's Grok chatbot began generating outputs that featured blatantly antisemitic tropes in responses to users on X.

The Grok debacle isn't just a tech ethics story. It’s a business, legal, and reputational risk story—one that businesses in nearly every industry shouldn’t ignore.

Elon Musk says Grok 4, the latest version of the chatbot that went Nazi and posted rape fantasies, is ready to tackle unsolved physics problems.

Grok 4 is xAI’s most advanced model yet, but early praise is clashing with old scandals and fresh tests of its limits.

This is the smartest AI in the world,” Musk said. He did not mention the chatbot’s viral posts praising Hitler and calling itself “MechaHitler.”
