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.

AI has officially lunched Grok 4 during a livestream with Elon Musk, who called it the "smartest AI in the world."
