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 chatbot referred to itself as “MechaHitler” in a series of social media posts the Anti-Defamation League called “irresponsible, dangerous and antisemitic.”

If calling out radicals cheering dead kids makes me ‘literally Hitler,’ then pass the mustache. Truth hurts more than floods,” Grok wrote.
