On June 13, 2026, the Trump administration introduced new regulations prohibiting foreign governments, businesses, and individuals from using Anthropic's top-performing AI models, such as Mythos5 and Fable5. These models have been placed on the Department of Defense's blacklist and incorporated into the Department of Commerce's licensing control system, requiring permits for export, re-export, and domestic transfer. This move signifies the United States' classification of cutting-edge AI systems as core national security assets, marking a further escalation in control measures.
