Claude Fable 5 Remains Banned 15 Days After US Government Shut It Down With No Return Date Fifteen days have passed since the US Commerce Department ordered Anthropic to pull Claude Fable 5 and Claude Mythos 5 from global availability. As of June 27, both models remain offline. No public restoration date has been confirmed. The directive, issued June 12 by Commerce Secretary Howard Lutnick, cited a jailbreak with national security implications and prohibited access by any foreign national anywhere in the world. Because Anthropic cannot verify user nationality in real time, the only way to comply was to take both models offline entirely. Fable 5 had launched June 9. It was live for three days. During those three days, it posted the highest score ever recorded on the FrontierCode production coding benchmark at 46.3%, more than 21 points above GPT-5.5. The model that briefly led every meaningful benchmark is now inaccessible. Multiple sources have identified Amazon as the company that flagged the underlying jailbreak to the Commerce Department, which layers competitive complexity onto an already politically charged situation. Anthropic filed a confidential IPO S-1 while both models sat offline, which raises its own questions about timing and disclosure. The precedent is what will be remembered. The US government pulled a commercially released AI model off the market on short notice, cited national security, and the company had no legal path to resist. Every AI lab watching this situation now understands that their products can be revoked after release. The industry is still working out exactly what that means for how frontier models get built and deployed going forward.
