At the launch of Grok-4, the xAI presenters prompted the chatbot to predict the World Series. After 4.5 minutes, it had an answer.

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.

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

AI removed numerous Grok posts on Tuesday after the chatbot praised Adolf Hitler and made antisemitic jokes. Now Musk says it's coming to Teslas.

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 confirmation followed a late-night livestream announcing xAI's Grok 4, where he claimed the new AI model was smarter than "almost all graduate students, in all disciplines, simultaneously," and could "discover new physics."

AI has officially lunched Grok 4 during a livestream with Elon Musk, who called it the "smartest AI in the world." He said that if you make the Grok 4 take the SATs and the GREs, it would get near perfect results every time and can answer questions it's never seen before.

Linda Yaccarino is stepping down as CEO of X after two years leading Elon Musk’s social media company. Yaccarino’s departure comes one day after the company’s Grok chatbot began pushing antisemitic tropes in responses to users. It’s not clear that the events were connected.
