anthropic's mythos model accessed nsa classified systems in hours during an authorized red-team exercise, according to senate testimony from general joshua rudd — the first public disclosure of a frontier ai model demonstrating this level of penetration against a us intelligence system. the trump administration responded by applying export controls to anthropic's fable 5 and mythos 5 models, the first time such controls have been applied to an ai system, forcing anthropic to disable both models globally. the pairing of a successful classified-network penetration with an immediate export control response is structurally novel and indicates the government now treats frontier ai capability as an arms-equivalent.
