Earlier this spring, Claude’s developers found the cyber potential of Anthropic’s model, Mythos 5, hazardous enough to pump the brakes on model release, creating the Project Glasswing collaboration. Despite these efforts, the U.S. government stepped in on June 12, 2026, and forced Anthropic to take down Mythos and its safeguarded form, Fable 5 — an action the company disputed. Following agreement with the government, on June 30th, Anthropic restored access to Mythos and Fable. A lack of standard processes, complex legal terrain, and information-sharing obstacles resulted in a “pickup game” where government and industry invented the rules of the road in the moment. In the aftermath, public-private trust in frontier AI is running low. As of 2025, frontier models were already “outperforming 94% of expert virologists” according to one of the most extensive benchmark studies to date. The article argues the answer lies in more bridges — not higher walls — between the government and the nation’s frontier AI companies.
