The Trump administration could lift access restrictions on Anthropic's Fable5 model as soon as within a week, Axios reported on June 27, citing sources familiar with the matter.

Fable5 has been blocked for 15 days due to government intervention over security concerns.

Another source said negotiations are expected to continue through the weekend and that Anthropic would soon be able to offer Fable5 again.

Axios said the outcome remains uncertain because the Department of Defense and the National Security Agency have not yet granted approval. It added that it is also unclear whether access will be restored for existing paid subscribers without additional fees or identity verification.

The U.S. Department of Commerce earlier said on June 26 it would allow Anthropic's cybersecurity model Mythos5 to be provided only to trusted partners.

Commerce Secretary Howard Lutnick said in a letter to Anthropic that the company had "worked with the government to address risks related to Mythos5 and Fable5" and that "this effort has made significant progress". Anthropic and OpenAI are both asking the administration to codify into formal procedures a voluntary government review framework established by President Trump in an executive order on June 2.

Fable5 drew a strong response among developers immediately after its release for its coding and deep-thinking capabilities. Payments company Stripe used Fable5 in early testing to improve a 50 million-line codebase in one day, a task that would take more than two months if engineers handled it manually.
