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.

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.

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