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.

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.”

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.

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.

After spending just over two years justifying Elon Musk's disastrous ownership over X-formerly-Twitter, CEO Linda Yaccarino has resigned.
