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 that the chatbot repeated an antisemitic meme and made positive references to Hitler.

Elon Musk said changes his xAI company made to Grok to be less politically correct had resulted in the chatbot being “too eager to please” and susceptible to being “manipulated.” That apparently led it to begin spewing out anti-Semitic and pro-Hitler comments on Musk’s X social platform Tuesday.
