The initiative hadn’t been planned to include xAI’s Grok model as recently as March, the former Pentagon employee said.

AI employees were asked to record facial expressions to train Elon Musk's AI chatbot Grok, raising internal privacy concerns.

In April, xAI asked workers to record their facial expressions as part of efforts to train Grok to understand human emotions, according to a report from Business Insider. During the process, xAI reportedly had employees sign a form that gives the company access to their “likeness” for training and “inclusion in and promotion of commercial products and services.

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.

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

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."

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 artificial intelligence startup xAI is working with a financier to secure up to $12 billion more for its expansion plans, the Wall Street Journal reported on Tuesday, citing people familiar with the situation.
