Overview
BREAKING: Anthropic just disabled Claude Fable 5 AND Mythos 5 for every user globally — even their own employees. US government directive, June 12, 2026, 5:21 PM ET. If your stack uses Fable 5, here are the 3 moves to make TODAY before Monday.
✅ Exact timeline — what happened June 12 + why Anthropic complied globally
✅ The "narrow jailbreak" reason the US government cited
✅ Why Anthropic disabled it WORLDWIDE instead of just for foreign users
✅ Exactly what's broken (web + API for both Fable 5 + Mythos 5)
✅ What's STILL working (Opus 4.8, Sonnet 4.6, Haiku 4.5 all fine)
✅ Move 1 — Audit your stack TODAY
✅ Move 2 — Build a real model fallback chain
