Elon Musk’s AI start-up xAI is working with Valor Equity Partners to secure up to $12 billion in financing for its rapid expansion, the Wall Street Journal reported Tuesday

Grok’s recent flirtation with extremism is just the latest example of an AI, left to its own devices, going off-script. What can, or should, be done to stop it?

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.

The announcement comes just days after Grok generated antisemitic responses and praised Hitler, which were later deleted.

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.

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."

AI explained why Grok 4 seemed to search for Elon Musk's opinions when asked about some hot-button topics.

Internal documents reveal Elon Musk's xAI used employee facial data in 'Project Skippy' to train its Grok AI, sparking internal backlash over data privacy.
