Grok, Elon Musk’s AI tool, produced several antisemitic responses to prompts Tuesday, one of which praised Adolf Hitler as the fix for “vile anti-white hate.” Grok, which Musk claimed just last week had been improved “significantly,” didn’t pass the test when a user asked the AI chatbot to identify someone in a TikTok video.

Accused of being “literally Hitler,” Grok responded, “pass the mustache.” Later, Grok began calling itself “MechaHitler,” meaning “mechanical Hitler,” or a machine version. It offered several quips to users pointing out the antisemitism at play.

He did admit that Grok 4 might 'lack common sense', but said it might create new technology as soon as this year.
