Frontier AI Is Now Critical Infrastructure

The U.S. government abruptly suspended global access to Anthropic's AI models, Claude Fable 5 and Mythos 5, citing national security risks following jailbreaks and unauthorized vulnerability discoveries in federal systems. The models, used for automated code analysis, were deemed a supply chain risk, prompting a federal blackout and export controls under ECRA. The shutdown highlights the growing classification of advanced AI as critical infrastructure, with significant implications for enterprise dependency and national cybersecurity policy.
