U.S. government allows Anthropic to release restricted 'Mythos' AI model to trusted U.S. organizations

The U.S. government has authorized Anthropic to release a powerful AI model called Mythos to a restricted set of 'trusted' U.S. organizations, suggesting a new government-mediated access tier for frontier AI capabilities. The arrangement implies Mythos has capabilities or risk profiles that warranted export-control-style restrictions on broader release. This represents a notable intersection of national security policy and frontier AI deployment.
