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.

Musk's announcement comes hours after xAI debuted its latest flagship AI model, Grok 4. The 54-year-old discussed the recent innovation during a nearly hour-long livestream shared on xAI's X page, during which he did not mention the chatbot's integration into Tesla vehicles.

Grok 4 is xAI’s most advanced model yet, but early praise is clashing with old scandals and fresh tests of its limits.

AI owner Elon Musk made some big claims about Grok’s capability, saying it was “better than PhD level in every subject.”

Elon Musk's artificial intelligence company took action against its Grok chatbot on Wednesday, removing a post it had made praising Adolf Hitler in response to a question related to the deadly Texas Hill Country flood.

Elon Musk said in a post on X early Thursday morning that Grok – the chatbot from his AI company, xAI – will be coming to Tesla vehicles “very soon.” “Next week at the latest,” he said.

Elon Musk’s live demo of Grok 4, the latest big-ticket model from his AI startup, began with high-intensity music, claims of a “ludicrous rate of progress,” and a lot of chatter on X about Grok’s scandal-filled week.
