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

Grok, a chatbot created by Elon Musk’s artificial intelligence company, xAI, shared several outlandish antisemitic comments on X on Tuesday, prompting an outcry from some social media users.

Grok has shared several antisemitic posts, including the trope that Jews run Hollywood, and denied that such a stance could be described as Nazism.
