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

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.
