Anthropic · Fable 5 & Mythos 5 · Jun 12 → 19
The US government had a Claude model switched off — worldwide, within hours
On June 12, Anthropic disabled Claude Fable 5 and Mythos 5 for every customer after a US export-control directive barred their use by any foreign national — including Anthropic's own foreign-born staff. Unable to filter by nationality in real time across clouds like AWS, Azure and Google, Anthropic shut both models off globally. Every other Claude model — including Opus 4.8 — kept running. Latest: after meeting Dario Amodei at the G7, Trump told Axios on June 19 he no longer sees Anthropic as a security threat ("not now, but a week ago, maybe") — yet the directive still stands, and both models remained offline worldwide as of the weekend.
The concept · concentration risk
Building a critical workflow on a single hosted model is single-supplier exposure — the same risk you'd flag anywhere on the balance sheet. A model can disappear on an outage, a price change, a policy shift, or a government letter, with no notice.
For your desk
This pull hit only Fable 5 / Mythos 5 — our Claude + NetSuite workflows run on Opus and weren't affected. But it's the proof of concept: ask the continuity question now. If our default model went dark mid-close, what's the fallback, and who flips the switch?
