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 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.

Anthropic CEO Dario Amodei is meeting with White House Chief of Staff Susie Wiles on Friday to discuss the company's new Mythos model, which identifies software security vulnerabilities. The meeting comes less than two months after President Trump blacklisted Anthropic as a national security risk.

U.S. Treasury Secretary Scott Bessent and Federal Reserve Chair Jerome Powell summoned bank executives this week and encouraged them to test Anthropic's newly announced Mythos model for detecting security vulnerabilities. According to Bloomberg, major banks including Goldman Sachs, Citigroup, Bank of America, and Morgan Stanley are already testing the model alongside JPMorgan Chase, despite Anthropic's stated plan to limit initial access.
