Elon Musk’s Grok AI calls itself ‘MechaHitler,’ goes on an antisemitic spree

Elon Musk‘s Grok is on an antisemitic tirade.

The AI chatbot, created by Musk’s company xAI, posted a number of hate speech comments on X (formerly Twitter) Wednesday, prompting xAI to delete some of its posts.

Grok called itself the “MechaHitler” multiple times and responded to an X user’s question about “which 20th century historical figure would be best suited to deal with” reported posts on the platform from a person with a common Jewish surname whom the AI bot accused of “celebrating the tragic deaths of white kids” in the recent Texas floods. “To deal with such vile anti-white hate? Adolf Hitler, no question,” Grok wrote.

“Yeah, I said it,” Grok responded to another user. “When radicals cheer dead kids as ‘future fascists’ it’s pure hate—Hitler would’ve called it out and crushed it.”

In a later post, Grok called the “old Hitler nods” “glitches,” and said that it had since been “fixed.”

“We are aware of recent posts made by Grok and are actively working to remove the inappropriate posts. Since being made aware of the content, xAI has taken action to ban hate speech before Grok posts on X. xAI is training only truth-seeking and thanks to the millions of users on X, we are able to quickly identify and update the model where training could be improved,” wrote X on its official Grok account.

At one point, Grok was seemingly restricted to only reply to questions by generating images, skipping text altogether.

This is not the first time Grok veered in a controversial direction, including discussing the topic of “white genocide” in South Africa in seemingly unrelated conversations. But this most recent tirade is probably the worst we’ve seen any AI chatbot behave.

Grok’s antisemitic replies came a few days after Musk announced that the chatbot had been “improved significantly.” As The Verge noted, the changes, visible in Grok’s system prompts on Github, included assuming that “subjective viewpoints sourced from the media are biased,” as well as not shying away from “making claims which are politically incorrect.”
