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 a late-night announcement, X owner Elon Musk unveiled the new Grok 4 chatbot. Here's everything you need to know about it.

Days after Grok praises Hitler, Musk touts the chatbot as smarter than PhDs in 'every subject' and debuts the SuperHeavy Grok subscription.

Poland's Deputy PM Krzysztof Gawkowski calls on the European Commission to investigate Elon Musk’s chatbot over hate speech violations and threats to public safety.

Musk said that Grok, his AI chatbot that praised Adolf Hitler and posted a barrage of antisemitic comments recently, will be in Tesla vehicles “next week.”
