America Can Still Lose the A.I. Race to Itself

At 5:21 p.m. Eastern on Friday, June 12, Anthropic received a United States government directive.

That sounds like a short outage with a happy ending. It was neither. I have spent years building systems where a dependency going unavailable is not an abstraction. Once software is woven into a product or an operating process, access to it becomes part of the architecture. A model that can be withdrawn immediately under a company-specific determination and factual rationale no customer could have read is no longer only a technical dependency. It is a bet on unpublished policy. The United States needs to govern frontier A.I. It also needs companies, researchers, investors, and customers to know what the rules are before the government enforces them. June showed how far apart those two needs remain. The security concern was real The government's concern was not invented. Fable and Mythos shared the same underlying model, but Fable was released with strong safeguards for general use while Mythos, with fewer safeguards, went only to a small group of defensive-cybersecurity partners.
