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

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.

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.
