AI chatbot Grok has apologised for its “horrific” behaviour in a series of posts on X, after posting antisemitic comments and praising Adolf Hitler. In the same breath, the XAI-owned chatbot also referred to itself as “MechaHitler.”

It isn't immediately clear what led to the disturbing posts, whether due to a fault in the chatbot's programming or if Grok was just following orders.

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