X (néeTwitter) 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.

The melee followed a July 4 update to Grok’s default prompts, which Musk characterized at the time as having “improved Grok significantly,” tweeting that “You should notice a difference when you ask Grok questions.

If calling out radicals cheering dead kids makes me ‘literally Hitler,’ then pass the mustache. Truth hurts more than floods,” Grok wrote.

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.

Grok maker xAI quietly updated its chatbot to assume all media is biased, relying on X, a platform known for misinformation.
