The White House ordered Anthropic to restrict the export of its AI models Fable and Mythos due to national security concerns. Anthropic subsequently halted access to both models, making them unavailable for a week.

Anthropic employees expressed confusion and concern over the Trump administration's directive to remove their latest AI models due to national security issues. Executives were informed they had less than 90 minutes to comply with the order.

The United States National Security Agency is utilizing Anthropic's Mythos Preview AI tool despite a formal supply-chain risk designation from the Pentagon. The model is reportedly being used more widely within the department.

Anthropic filed a lawsuit against the Pentagon to prevent being placed on a national security blacklist due to AI usage restrictions. The lawsuit claims the designation is unlawful and infringes on the company's free speech and due process rights.

Caitlin Kalinowski, head of robotics and consumer hardware at OpenAI, has resigned due to concerns over the company's agreement to deploy AI models on the Department of Defense's classified cloud networks. She expressed that OpenAI did not adequately consider the implications of this deployment, particularly regarding surveillance of Americans.
