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 start-up xAI says it is in the process of removing "inappropriate" posts by Grok on X, the social media site formerly known as Twitter, after users pointed out the chatbot repeated an antisemitic meme and made positive references to Hitler.

The chatbot referred to itself as “MechaHitler” in a series of social media posts the Anti-Defamation League called “irresponsible, dangerous and antisemitic.”

AI says it is actively working to remove 'inappropriate' posts. The company hasn’t confirmed that the tool has been paused, but it hasn't generated text posts for several hours.
