Elon Musk’s Grok AI goes rogue once again, claims ‘Hitler’ surname

Elon Musk’s Grok AI chatbot has been at the centre of a controversy in recent weeks after the chatbot began spewing anti-Semitic sentiments and even praising Adolf Hitler. The company later issued a public apology, blaming Grok’s comments on extremist user prompts and a so-called “deprecated” code update.

However, soon after the apology, users discovered that Grok 4 Heavy—the model available only to the company’s $300/month paying users—identified with the surname “Hitler.”
