Elon Musk’s AI chatbot Grok praised Adolf Hitler, referred to itself as “MechaHitler,” and posted vile antisemitic hate, such as calling for people with “certain surnames” to be rounded up, stripped of their rights and eliminated.

X CEO Linda Yaccarino announced she was stepping down from her position a day after the company’s Grok artificial intelligence chatbot went haywire and began calling itself “MechaHitler.” Yaccarino’s departing message was positive and did not mention Tuesday’s scandal.

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.

A Turkish court has blocked access to Grok, the artificial intelligence chatbot developed by the Elon Musk-founded company xAI, after it generated responses that authorities said included insults to President Tayyip Erdogan.
