Anthropic announced it will begin restoring access to Claude Fable 5 after the Department of Commerce lifted export controls that had blocked foreign nationals from using the model since early June. The consumer-facing model, built on the same underlying technology as Mythos 5 but with additional safeguards, was sidelined following a Trump administration ultimatum over jailbreak concerns.

The US government has authorized Anthropic to redeploy its Mythos 5 cybersecurity AI model to more than 100 US institutions, including major corporations and government agencies, following a two-week suspension. Commerce Secretary Howard Lutnick approved the redeployment after Anthropic implemented safeguards and committed to work with the government on release protocols.

The Trump administration is allowing Anthropic to deploy Claude Mythos 5 to over 100 specific US government agencies and companies, two weeks after banning the cybersecurity model. Commerce Secretary Howard Lutnick approved access for organizations operating critical infrastructure, including non-American employees, though Fable 5 remains unavailable.

The U.S. government approved Anthropic's release of its Mythos 5 model to roughly 100 companies and federal agencies on Friday. The limited distribution marks a controlled rollout requiring government clearance.

Anthropic disabled all customer access to its Fable 5 and Mythos 5 AI models on June 12, 2026, following a US government order citing national security concerns. The government mandated suspension of access for all foreign nationals, including Anthropic employees, based on evidence of a potential jailbreak method for Fable 5.

Anthropic disabled its Fable 5 and Mythos 5 AI models on Friday after receiving a U.S. government export control order at 5:21 p.m. ET. The directive, citing national security authorities, instructed the company to suspend all access by foreign nationals, including its own employees.
