Overview
- The Commerce Department ordered Anthropic to block foreign‑national access to Fable 5 and Mythos 5, and the company disabled both models for all users to comply.
- The directive, issued on June 12, cited a reported prompt‑based 'jailbreak' that officials said created national security risks, though Anthropic says the flaw was narrow and already patched.
- Anthropic and White House and Commerce officials have held daily technical and policy talks and are drafting a shared risk‑assessment framework that would set conditions for future government interventions.
- Allied governments raised alarm at G7 discussions and pressed for 'trusted partner' arrangements or independent compute, and European leaders warned the episode highlights dependence on U.S.‑hosted frontier AI.
- The shutdown has rattled investors and cloud customers, creating fresh uncertainty for Anthropic’s planned IPO and underscoring limits of export controls over cloud software given past failures to contain software proliferation.
