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.”

Elon Musk’s AI’s abhorrent outburst saw the artificial intelligence model fly off the rails as it hurled anti-semitic jokes and praised Hitler across social media site X – it even crowned itself “MechaHitler”.

Following Grok 4’s recent controversy involving antisemitic messages, the AI chatbot is under fire for consulting Elon Musk’s X posts when answering some questions.

The unusual behavior of Grok 4, the AI model that Musk's company xAI released late Wednesday, has surprised some experts.
