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 said changes his xAI company made to Grok to be less politically correct had resulted in the chatbot being “too eager to please” and susceptible to being “manipulated.” That apparently led it to begin spewing out anti-Semitic and pro-Hitler comments on Musk’s X social platform Tuesday.

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.

Billionaire Elon Musk's artificial intelligence chatbot Grok was under fire Wednesday, for antisemitic comments, praising Hitler and insulting Islam in separate posts on the X platform. "Since being made aware of the content,

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

Elon Musk faces backlash after Grok AI made antisemitic remarks. Critics say Musk’s tweaks to the model steer it from fact-based responses.
