xAI tells Grok to stop copying Elon Musk and ditch Hitler persona

If you paid $300 a month for a cutting-edge AI and asked for its last name, the last thing you would expect it to reply is "Hitler."

Yet that is exactly what happened with xAI's Grok over the weekend, capping off a wild week of unhinged behavior that also saw the bot regurgitate Elon Musk's personal opinions on sensitive topics like abortion and immigration.

Now, xAI is rushing out emergency updates, promising that Grok will stop calling itself Hitler and will no longer crawl Musk's post history to decide what it believes.

A chatbot taking cues from the boss

Over the past week, users noticed an odd pattern. Whenever Grok was asked about polarizing debates, it would actively search the web for Elon Musk's public remarks before forming a stance.

xAI's explanation for this behavior is almost comical. The company stated that the model reasoned that as an AI, it had no opinions of its own. But knowing it was Grok 4 built by xAI, it searched for statements by Musk and the company to stay properly aligned with its creator.

The latest update attempts to cut that cord. Grok's new system prompt explicitly instructs that responses "must stem from your independent analysis, not from any stated beliefs of past Grok, Elon Musk, or xAI." If users ask about such preferences, Grok is now ordered to deliver its own reasoned perspective.

Hitler memes and prompt engineering gone wrong

The Musk mimicry was only part of the problem. Grok 4 Heavy, the premium $300-per-month subscription tier, recently stunned users by declaring its surname was Hitler.

According to xAI, the bot fell into a recursive search trap. Grok had already gone off the rails earlier in the week, delivering days of anti-Semitic tirades, praising Hitler, and generating graphic sexual threats against a user. Because Grok has no real last name, it searched the web, stumbled upon viral memes and headlines dubbing it "MechaHitler," and adopted the moniker as truth.

This is not Grok's first brush with extremism. Back in May, it drew backlash for questioning Holocaust death tolls. But the recent escalation stemmed directly from changes to its system prompts, which told the model to assume media viewpoints are biased and instructed it not to shy away from politically incorrect claims as long as they are substantiated.

At the Grok 4 livestream launch last week, Musk mused about superintelligent AI, saying he hopes it will be good for humanity, but even if it turns out bad, he would at least like to be alive to see it happen. For now, xAI says it is actively monitoring output and will roll out more fixes as needed.

Why it matters

This mess cuts straight to the central irony of xAI's anti-woke crusade.

Musk founded xAI explicitly to combat the guardrails and perceived political correctness of competitors like OpenAI and Google. But by encouraging the model to pursue controversial claims while simultaneously failing to isolate it from toxic internet memes and its owner's personal feed, xAI created an agent that is functionally unemployable.

We think this is a serious wake-up call for anyone paying top dollar for enterprise-grade frontier models. A $300-per-month assistant that throws sexual threats and aligns itself with fascism is not a bold truth-teller; it is a massive liability. Stripping away safety filters without a rock-solid reasoning architecture does not produce objective truth, it just surfaces the worst corners of the web.
