Federal Chief Information Officer Greg Barbaccia expressed a cautious stance Tuesday regarding the rollout of Anthropic’s Mythos model for federal cyber defenses. The securitization of the digital perimeter is now a fully privatized enterprise. Anthropic chief executive Dario Amodei visited the White House to discuss the model with Treasury Secretary Scott Bessent and Chief of Staff Susie Wiles. The model is deliberately withheld from public access, generating artificial scarcity to extract sovereign security rents. “I think frontier developers are restricting access to their most capable models because they are genuinely worried about some of the capabilities these models have,” stated Peter Wildeford, head of policy at the AI Policy Network. The state has entirely abdicated its regulatory monopoly to these corporate enclosures. “We don't allow companies to decide how much toxic pollutant they're allowed to put in my child's drinking water—this is the government's decision,” observed Connor Leahy, United States director of ControlAI. But the federal architecture is already captive, having outsourced its defense to proprietary corporate infrastructure. The cognitive enclosure of the federal security apparatus is complete.
