US Government Partially Lifts Restrictions on Anthropic's Mythos 5 AI Model
The U.S. government has revised its license requirements for Anthropic's Mythos 5 AI model, allowing over 100 specific U.S. companies and government agencies limited access. The move follows a two-week ban on the cybersecurity-focused model, though restrictions on the public-facing Fable 5 model remain in place.

TL;DR
- The Commerce Department's order on June 12 effectively removed Anthropic's Mythos 5 and Fable 5 from the market.
- The ban was justified as an export-control step to curb risks from advanced cyber capabilities.
- After two weeks of negotiations, license requirements for Mythos 5 were revised on June 26.
- Over 100 U.S. government agencies and companies are now authorized to use Mythos 5, including their non-American employees.
- Fable 5 remains in limbo with no public timeline for its re-release for general use.
- AI export policy for high-capability models is described as ad hoc and subject to rapid change.
