TL;DR
- The US government issued an emergency export control directive forcing Anthropic to immediately suspend access to its flagship Fable 5 and Mythos 5 AI models for all foreign nationals due to national security concerns.
- To guarantee absolute compliance with the order, Anthropic had to completely disable both models for all customers worldwide, including domestic US citizens.
- The restriction stems from a codebase “jailbreak” exploit that allows users to use these models to scan for software vulnerabilities.
- Anthropic strongly pushes back, arguing the flaw is minor, present in competitor models like GPT-5.5, and shouldn’t trigger a commercial blackout.
In a stunning and unprecedented move, the US government has issued an emergency export control directive forcing Anthropic to immediately suspend all access to its flagship Fable 5 and Mythos 5 artificial intelligence models within Claude.
According to an official statement released by Anthropic, the US government’s directive arrived abruptly on June 12, citing national security authorities but offering little initial documentation. The US government has directed Anthropic to suspend all access to Fable 5 and Mythos 5 by any foreign national, whether inside or outside the United States, including foreign national Anthropic employees.
However, the net effect of this order is that Anthropic has had to disable Fable 5 and Mythos 5 for all its customers, including US nationals, to ensure complete compliance. Anthropic notes that access to all other Anthropics models is not affected.
While Anthropic has complied with the legal mandate, the company expressed strong disagreement with the decision, calling it a “misunderstanding” and warning that such an opaque intervention could freeze progress across the entire tech sector.
