The U.S. partially eases export restrictions on Anthropic, marking a new phase of tiered AI regulation liberalization

Odaily reported that the U.S. Department of Commerce has made differentiated adjustments to export restrictions on frontier models from AI company Anthropic, signaling that global AI regulation has entered a new phase of "tiered liberalization." The policy shows that the official ban on exporting Claude Mythos 5 has been lifted, allowing specific compliant and controlled users to resume using this cybersecurity model. Meanwhile, another high-end model, Fable 5, remains under export restrictions, with related policy consultations still ongoing.

Industry analysts indicate that this layered control model—loosening restrictions in some areas while tightening in others—reflects the U.S. balancing act between national security, data sovereignty, and international AI competition. As the global AI race continues to accelerate, specialized models capable of vulnerability exploitation are facing increasingly stringent scrutiny from various countries. Multiple nations have initiated discussions on establishing a unified cross-border regulatory framework for frontier AI capabilities. (Forbes)
