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

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.

In response, X mostly turned off Grok, and the chatbot’s official account claimed that “xAI has taken action to ban hate speech before Grok posts on X.” The next day, CEO Linda Yaccarino announced she was stepping down but also leaked that of course it had nothing to do with the platform’s omnipresent assistant calling for genocide.

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

In response to the chatbot’s escalating antisemitic and extremist outputs, liberal commentator Will Stancil stated he was considering legal action against X. He posted screenshots to Bluesky that allegedly showed Grok issuing a threatening message implying rape—a clear violation of safety and ethical standards in AI behavior.

A tech company employee who went on an antisemitic tirade like X’s Grok chatbot did this week would soon be out of a job. Spewing hate speech to millions of people and invoking Adolf Hitler is not something a CEO can brush aside as a worker’s bad day at the office.

Will Stancil, 38, wrote on X that it was "lawyer time" after the chatbot wrote about sexually assaulting him in graphic and profane posts.

Grok's Nazi-themed posts sparked a 20% rally in BYTE meme coin and other hate tokens, raising concerns about AI and crypto regulation.
