Summary
The Trump administration’s directive specifically targets Mythos-class models, which include Fable 5. Commerce Secretary Howard Lutnick sent the directive to Anthropic CEO Dario Amodei, requiring a license for the export, re-export, or domestic transfer of the two models, and extending the restrictions to any foreign person on U.S. soil. Anthropic said the letter gave no specifics, and that the government has so far supplied only verbal evidence pointing to a narrow, non-universal jailbreak. "We believe this is a misunderstanding," the company wrote, adding that it’s complying with the order while working to restore access.
