Claude Fable 5 just got suspended by the US government. Here's what happened, why, and what it means if you were using it. A US export-control order told Anthropic to cut off Fable 5 and Mythos 5, so they disabled both for everyone. Every other Claude model (Opus 4.8 and down) still works. The trigger was a narrow security "jailbreak" (getting the model to read a codebase and find its flaws), which Anthropic says other models, including OpenAI's GPT-5.5, can already do. They're complying with the order but disagree with it. For you: new Claude and Claude Code sessions fall back to Opus 4.8, open Fable sessions error out, and Fable 5 API requests (how other apps connect to it) return an error, so update your integrations. Refunds are community-reported, not official: if you upgraded to Max just for Fable, people are saying the Claude support chat is refunding them right away, often prorated. Anthropic also says it's working to restore access, so this might not be permanent.
