Story summary

Anthropic halted Claude Fable 5 and Claude Mythos 5 after a U.S. Commerce Department export-control order.
The order arrived at 5:21 p.m. ET on June 12, barring foreign-national access over a jailbreak security concern.
Anthropic disabled the models for all customers, apologized, called the directive a misunderstanding, and urged a switch to other Claude versions.
It noted other Anthropic models stay available and that similar jailbreak exploits exist in OpenAI’s GPT-5.5.

History

Historical Context

1996 Executive Order 13026, signed by President Bill Clinton, moved commercial encryption to the Commerce Control List after PGP’s 1991 challenge and Netscape’s weak-key browsers. A 1999 amendment then required licenses for encryption software under the EAR. In 2024 the U.S. Department of Commerce’s order forced Anthropic to halt its Claude Fable 5 and Claude Mythos 5 models, reflecting the same export-control legacy.
