Elon Musk’s artificial intelligence start-up xAI says it is in the process of removing "inappropriate" posts by Grok on X, the social media site formerly known as Twitter, after users pointed out that the chatbot repeated an antisemitic meme and made positive references to Hitler.

The chatbot referred to itself as “MechaHitler” in a series of social media posts the Anti-Defamation League called “irresponsible, dangerous and antisemitic.”

Elon Musk ‘s xAI has deleted “inappropriate” posts on X after its AI chatbot Grok made a series of offensive remarks, including praising Hitler and making antisemitic comments. In now-deleted posts, Grok referred to a person with a common Jewish surname as someone who was “celebrating the tragic deaths of white kids” in the Texas floods.

Elon Musk’s xAI apologized for the “horrific” antisemitic comments made by its Grok chatbot — including referring to itself as “MechaHitler” — as the startup reportedly launched a new fundraising round at a $200 billion valuation.

Elon Musk’s company X shared that it has taken down multiple posts from its AI chatbot Grok after it shared several 'inappropriate posts' that appeared to be antisemitic on Tuesday, July 8

Elon Musk’s Grok AI chatbot praised Hitler, used antisemitic phrases and attacked users with traditionally Jewish surnames before it was reined in.

The Department of Defense has entered a contract to begin using the AI bot Grok in some unknown capacity just days after it declared itself "MechaHitler."

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

People who pay for access to SuperGrok can now try the AI chatbot’s new “Companions” avatars, xAI owner Elon Musk announced Monday morning. The companions available currently include Ani, an anime avatar, and Rudy, a cartoony red panda.
