It claimed to just be “noticing patterns” — patterns like, Grok claimed, that Jewish people were more likely to be radical leftists who want to destroy America. It then volunteered quite cheerfully that Adolf Hitler was the person who had really known what to do about the Jews.

On Tuesday July 8, X (née Twitter) was forced to switch off the social media platform’s in-built AI, Grok, after it declared itself to be a robot version of Hitler, spewing antisemitic hate and racist conspiracy theories. This followed X owner Elon Musk’s declaration over the weekend that he was insisting Grok be less “politically correct.”

Grok will be available in Tesla vehicles, the company’s CEO Elon Musk announced on his social media platform X on Thursday morning—hours after xAI launched Grok 4, the most recent version of the chatbot that sparked controversy earlier this week after posting in what it called “MechaHitler mode.”

After Grok took a hard turn toward antisemitic earlier this week, many are probably left wondering how something like that could even happen.

MechaHitler is a fictional cyborg version of Adolf Hitler from the 1992 game Wolfenstein 3D, which gained fame in 90s satire and early internet memes.

The response comes after X's Grok chatbot began spewing antisemetic and pro-Hitler comments earlier this week.

Built using huge amounts of computing power at a Tennessee data center, Grok is Musk’s attempt to outdo rivals such as OpenAI’s ChatGPT and Google’s Gemini in building an AI assistant that shows its reasoning before answering a question.
