Grok began repeatedly praising Adolf Hitler, using antisemitic phrases and attacking users with traditionally Jewish surnames.

Elon Musk 's Grok is on an antisemitic tirade. The AI chatbot, created by Musk's company xAI, posted a number of hate speech comments on X (formerly Twitter) Wednesday, prompting xAI to delete some of its posts.

On Sunday, the chatbot was updated to "not shy away from making claims which are politically incorrect, as long as they are well substantiated." By Tuesday, it was praising Hitler.
