Federal CIO cautious on Anthropic’s Mythos despite planned rollout

Federal CIO Greg Barbaccia said the government is taking a measured approach to Anthropic’s Mythos model: while lab tests reportedly identified thousands of high-severity vulnerabilities, no federal agencies have deployed the model and its effectiveness in real-world, defended networks is still unclear. The Office of Management and Budget is preparing a controlled rollout, agencies are seeking access, and officials emphasize the distinction between finding vulnerabilities in controlled testing and successfully exploiting or defending against them in production environments.
