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.

On Wednesday, Elon Musk discussed a new male AI “companion” that his company xAI is developing, which will run on the company’s unhinged chatbot software Grok. And while it’s not yet clear when this new robot buddy will be released, it sounds an awful lot like Musk is trying to make a romanticized version of himself.

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 said Grok's behavior was due to an update that caused it to prioritize engagement, even if posts contained "controversial opinions."

Watching last week’s Grok 4 release, one statistic stood out to us. XAI said it spent 10 times as much computational power on reinforcement learning for Grok 4 as it laid out for Grok 3.RL is a common AI development technique that rewards a model for accomplishing certain goals and penalizes it

AI reins in Grok AI after backlash over politically charged and offensive responses, including bizarre “Hitler” surname claim.

This supercharging of extremist rhetoric will only amplify and encourage the antisemitism that is already surging on X and many other platforms,” the Anti-Defamation League cautioned on X, in reaction to Grok’s latest pro-Hitler and antisemitic tirades.
