US Clears Anthropic to Deploy Mythos 5 to 100+ Organizations

The Trump administration has authorized Anthropic to release its flagship AI model, Claude Mythos 5, to more than 100 organizations including Fortune 500 companies, ending a temporary export-control freeze that began two weeks ago. Commerce Secretary Howard Lutnick informed Anthropic co-founder Tom Brown in a letter that the department had determined “appropriate safeguards are in place,” according to reports from WIRED and Reuters.

The partial lift covers only trusted partners. Foreign employees of those organizations can also access the model, Lutnick wrote. The decision came a day after the administration asked OpenAI to stagger the release of its upcoming GPT 5.6 model, releasing it first to a shortlist of government-approved partners.

The administration froze access to Mythos 5 and its more powerful sibling, Fable 5, after the government found that Anthropic had granted access to a South Korean telecommunications company believed to have ties to China. Amazon and the National Security Agency separately flagged that Fable 5 could be jailbroken, the reports said.

Anthropic responded by deploying senior members of its cybersecurity and AI safety teams to Washington to work with regulators. Lutnick cited that cooperation in his letter: “Anthropic has worked with the U.S. government to address risks associated with the Covered Models. These efforts have yielded significant progress.”

The pattern is emerging as a template for advanced AI oversight. The government clears models for trusted commercial use after securing concessions but reserves the right to restrict them over foreign intelligence or proliferation concerns. For Amazon, which holds a major stake in Anthropic and raised jailbreak concerns about Fable 5, the resolution removes a near-term risk to its cloud AI business. The model at issue here, Mythos 5, is specifically designed for cybersecurity tasks.

Anthropic spokesperson Eduardo Maia Silva confirmed to WIRED that the model will again be available to “a small group of cyber defenders and infrastructure providers.” He said the company is “working to provision the approved set of providers and restore their access to Mythos 5 as quickly as possible.”

Fable 5 remains blocked for general use. Silva said the company is continuing negotiations with the White House, and those talks are expected to run through the weekend. No timeline has been set for a consumer-facing version of Mythos 5, the reports said.

Anthropic said it is “pleased to see this progress” and will continue working with the government to expand access to both models. The next concrete marker is the fate of Fable 5, which remains in limbo as the company and the White House negotiate safeguards.
