AI supply-chain alert: US export controls disable Claude Fable 5 & Mythos 5 globally

🚨 AI SUPPLY-CHAIN ALERT — a single regulator just pulled two AI models offline worldwide.

On 12 Jun 2026, a US government export-control directive forced Anthropic to abruptly disable Claude Fable 5 and Mythos 5 for all customers globally — citing national-security authorities and a known model jailbreak. Existing sessions error out; API calls fail. Opus, Sonnet, and Haiku are unaffected.

Threat-intel takeaway: model availability is now a geopolitical supply-chain risk. One regulatory action can drop a production dependency with zero notice — if your stack hard-codes a single model, that's a single point of failure. Build model-agnostic fallbacks.
