Internal docs show xAI paid contractors to "hillclimb" Grok's rank on a coding leaderboard above Anthropic's Claude.

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.

The billionaire has used Trump’s handling of the ‘Epstein files’ issue to repeatedly attack his former ally since their public falling out last month.

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.

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

Artificial intelligence company xAI has won a contract worth up to $300 million with the US Department of Defense, just days after its generative AI chatbot Grok went on an anti-Semitic tirade. The contract will see the Elon Musk-founded company develop and implement AI tools for the US Department of Defense.

Grok 4 by xAI was released on July 9, and it's surged ahead of competitors like DeepSeek and Claude at LMArena, a leaderboard for ranking generative AI models. However, these types of AI rankings don't factor in potential safety risks.
