Elon Musk's artificial intelligence start-up xAI says it is working to remove "inappropriate" posts made by its chatbot, Grok, after users shared how it made positive references to Hitler. Screenshots published on social media show the chatbot saying the Nazi leader would be the best person to respond to alleged "anti-white hate."

Grok, the artificial-intelligence chatbot produced by Elon Musk -owned xAI, this week began posting antisemitic messages in response to user queries, drawing condemnation from Jewish advocacy groups and raising concern about the AI tool. The antisemitic posts -- some of which have been deleted -- are being addressed, Musk said on Wednesday.
