Elon Musk’s company xAI apologized after Grok posted hate speech and extremist content, blaming a code update and pledging new safeguards to prevent future incidents.

In a series of posts on X, the AI chatbot Grok apologized for what it admitted was “horrific behavior.” The posts appear to be an official statement from xAI, the Elon Musk-led company behind Grok, as opposed to an AI-generated explanation for Grok’s posts.

Elon Musk's xAI startup is swimming in controversy after launching Grok 4, the latest version of its snarky AI chatbot. Last week, the company boasted that Grok 4 achieved higher scores than quite a few other large language models (LLMs) on various industry benchmarks.

But the Grok account on X that runs off the model immediately showed there were some major issues: It started saying its surname was “Hitler”, tweeted antisemitic messages, and seemed to reference Elon Musk’s posts when asked about controversial topics, siding with the xAI owner’s views as a result.

A week after Grok's antisemitic outburst, which included praise of Hitler and a post calling itself "MechaHitler," Elon Musk's xAI has landed a US military contract worth up to $200 million. xAI announced a "Grok for Government" service after getting the contract with the US Department of Defense.

Elon Musk on Wednesday unveiled Grok 4, a new version of his X platform's AI chatbot. The update comes a day after the bot posted antisemitic content on the social media network. Musk introduced the new model in a livestream on X late Wednesday, calling Grok 4 "the smartest AI in the world."

Elon Musk’s artificial intelligence company said its Grok chatbot had also undergone a code update that caused it to share antisemitic messages this week.

The companions have their own X accounts, because of course they do. Ani's bio states, "Smooth, a little unpredictable—I might dance, tease, or just watch you figure me out. Let’s keep it chill… or not." Meanwhile, Rudy's just says, "The Only Pet in Grok Companion."
