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

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

Elon Musk and xAI employee announced on Wednesday night the launch of the startup's next flagship AI model, Grok 4.

Grok AI will be available in Tesla vehicles next week "at the latest", the EV maker's CEO, Elon Musk, said in a post on X on Thursday.

The xAI chatbot will arrive on Tesla vehicles by “next week at the latest,” according to Elon Musk, who previously said in January that it was “coming soon.” This wasn’t mentioned during last night’s live demo of Grok 4.

As Grok fired off replies on X praising Hitler, the chatbot's parent company also recently got permission to emit 97 tons of carbon monoxide per year to keep it running.

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.
