Overview
- On June 12 the Commerce Department’s Bureau of Industry and Security ordered Anthropic to block foreign‑person access to Fable 5 and Mythos 5, and Anthropic disabled both models worldwide to comply.
- Authorized testing under Project Glasswing showed an Anthropic Mythos‑class model could identify vulnerabilities in highly sensitive U.S. government computer systems within hours, officials told reporters.
- More than 100 cybersecurity experts and industry leaders warned the restriction could weaken U.S. defenses because defenders use similar models to find and fix flaws and comparable abilities exist in other commercial and open‑source systems.
- Legion LegalTech filed a federal lawsuit on June 23 challenging the BIS directive, saying the order immediately sidelined its Canada‑based developers and caused irreparable harm to its business.
- The Five Eyes cyber chiefs issued a joint warning that frontier AI will reshape cyber risk within months, a statement that has increased diplomatic pressure and raised legal and policy questions about applying export controls to live cloud services.
