Fable 5 is back globally as of July 1 after US export controls (June 12–30) triggered by an Amazon-discovered jailbreak; a new classifier blocks the technique in over 99% of cases.
**The gist** Anthropic restored global access to **Fable 5 on July 1, 2026**, after US export controls suspended it on **June 12** — three days post-launch. Amazon researchers had jailbroken it into producing exploit-demonstration code for a software vulnerability; Anthropic's testing found **Opus 4.8, GPT-5.5, and Kimi K2.7** could produce the same demonstration. A new classifier blocks the technique in **over 99%** of cases.
**Why it matters** If Fable 5 vanished from your stack mid-June, this is why, and it is back: Pro, Max, and Team plans get it within up to **50% of weekly limits through July 7**, then via usage credits. The episode also shows how fast a government can pull a frontier model — a fallback model in any production harness is no longer paranoia.
