Historical Anomaly: The Open Frontier Is Narrowing

Summary

Follow-up to the February 23 argument that broadly available frontier AI access is a historical anomaly: sixteen weeks later a U.S. Commerce export-control directive cut off foreign-national access to the two most powerful Anthropic models, which were pulled for all customers to comply.

Key claims

• The predicted ratchet pattern — access controls tightening under a national-security frame, not loosening — is no longer hypothetical. [^src:articles-published §historical-anomaly-open-frontier]
• Opus-class access remains open, and teams that build during this window carry a meaningful head start into the restricted era. [^src:articles-published §historical-anomaly-open-frontier]
• The most valuable period for building may be precisely the one before the gates tighten. [^src:articles-published §historical-anomaly-open-frontier]
