🚨 Anthropic says the U.S. government ordered it to suspend access to Fable 5 and Mythos 5 for all foreign nationals 🚨
Anthropic says it has been directed by the U.S. government to suspend all access to Fable 5 and Mythos 5 for any foreign national, including foreign national employees, which forces the company to disable the models for all customers. The company says the order was driven by national security concerns tied to a possible jailbreak method.
🔑 Key highlights:
🔹️ Anthropic says the U.S. government issued an export control directive on June 12, 2026.
🔹️ The order requires Anthropic to suspend access to Fable 5 and Mythos 5 for any foreign national, whether inside or outside the United States.
🔹️ Anthropic says the practical result is that it must disable both models for all customers to comply.
🔹️ The company says the government’s concern appears to involve a reported method for bypassing or “jailbreaking” Fable 5.
🔹️ Anthropic argues the reported issue was narrow and related to previously known minor vulnerabilities, not a universal jailbreak.
🔹️ Anthropic says it has not received evidence of a harmful non-universal jailbreak result.
🔹️ The company says it disagrees with the government’s action and believes the standard could chill frontier model deployment across the industry.
🎯 Bottom Line: Anthropic says the government’s order forces it to pull Fable 5 and Mythos 5 offline for all users, and it calls the decision a misunderstanding.
