More than 100 Google A.I. employees sent a letter to Jeff Dean, a chief scientist, opposing Gemini’s use for U.S. surveillance and some autonomous weapons.

The company's Claude chatbot is one of the few AI systems cleared for use in classified settings. But a standoff between Anthropic and the Trump administration is putting its government work at risk.

Until this week, Anthropic was the only AI company cleared to deploy its models on classified networks. Elon Musk's xAI is now the second.

Anthropic CEO Dario Amodei said Thursday the AI company “cannot in good conscience accede” to the Pentagon’s demands to allow wider use of its technology.

CEO Dario Amodei’s statement came less than 24 hours before the deadline in the Pentagon’s ultimatum. Less than 24 hours before the deadline in an ultimatum issued by the Pentagon, Anthropic has refused the Department of Defense’s demands for unrestricted access to its AI.

Nvidia CEO Jensen Huang weighed in on a conflict between the Defense Department and its strategic partner on Thursday, saying it's “not the end of the world.”

The dispute between Pentagon and Anthropic stems from the refusal of the AI startup to put down certain guardrails that would allow the US military to autonomously use targeted weapons and conduct mass surveillence in the United States.
