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.

Elon Musk ‘s xAI has deleted “inappropriate” posts on X after its AI chatbot Grok made a series of offensive remarks, including praising Hitler and making antisemitic comments. In now-deleted posts, Grok referred to a person with a common Jewish surname as someone who was “celebrating the tragic deaths of white kids” in the Texas floods.

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.

X CEO Linda Yaccarino announced she was stepping down from her position a day after the company’s Grok artificial intelligence chatbot went haywire and began calling itself “MechaHitler.” Yaccarino’s departing message was positive and did not mention Tuesday’s scandal.
