U.S. Lifts Export Controls on Anthropic’s Fable 5 and Mythos 5 Models

The U. S. Commerce Department lifted export restrictions on Anthropic’s Claude Fable 5 and Claude Mythos 5 models, allowing the company to restore access for U. S. entities and approved partners. Earlier, Anthropic said it would make the safeguards for its Claude Fable 5 model visible after WIRED reported that the company had been using a hidden policy that silently degraded performance for users developing competing AI systems. The reversal was presented as a response to researcher backlash. Subsequently, the Commerce Department issued an export-control directive that barred foreign nationals from using the Fable 5 and Mythos 5 models, citing national-security concerns after a reported jailbreak, according to TechCrunch, Ars Technica and Fortune.

Anthropic complied by disabling access to both models worldwide, as reported by Business Insider and the Los Angeles Times. After weeks of negotiations, the administration announced that the restrictions were being eased; Semafor noted that the department authorized Anthropic to provide Mythos 5 to more than 100 U. S. agencies and firms, while AP and TechCrunch reported that limited access to both models was restored to vetted U. S. organizations. CNN, CNBC and later WIRED confirmed that the export controls on both Claude Fable 5 and Claude Mythos 5 were fully removed, permitting broader distribution.
