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.

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.

Authorities said the chatbot generated responses insulting the strongman president, modern Turkey's founder Mustafa Kemal Ataturk and religious values.

A change to Grok’s internal instructions, or system prompt, is leading users to accuse Elon Musk’s AI of a renewed rightward tilt. The new instructions tell it to assume some media information is biased.

Elon Musk wants to build a new political party to challenge America's two-party system. But it won't be easy, even for the world's richest man.
