The Commerce Department used emergency export authority to lock non-citizens—including Anthropic's own foreign employees—out of frontier AI systems. This marks the first use of model access restrictions, rather than weights or code controls, as a governance mechanism. The approach is more aggressive than traditional open-sourcing debates because it operates at runtime rather than release, effectively nationalizing frontier capability while keeping the company domestic. The precedent gives Washington a way to manage AI competition without formal legislation, converting access control into a de facto industrial policy tool.
