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’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.

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

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.

AI, Elon Musk’s AI company, has posted a new job listing for a Waifu engineer, just days after unveiling its AI companions for Grok.

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
