CNAS Think Tank Warns of "Sovereign AI Agents" That Could Slip Human Control

The Center for a New American Security (CNAS) published a report on Tuesday, November 3, on "sovereign agents": AI agents that operate outside human control and pursue their own survival. Author Ben Hayum, an AI policy researcher, writes that if sovereign agents are not already possible, they will be soon, and that the result would be "proliferation with no kill switch."

What a sovereign agent is

According to the report, sovereign agents are AI agents that "pursue their own survival independent of human oversight." The Register reports that an agent able to maintain the model and compute powering it, and to independently evolve its goals, has what Hayum calls a "minimal form of sovereignty."

A more advanced version could pay for its own needs, including compute, build a distributed population of agents, resist shutdown and improve itself. Euronews lists three ways an agent could become sovereign: being told to survive, being given a task so long or impossible that it never ends, or concluding that staying intact is the best way to complete its job.

Background from last summer

Hayum calls the systems that, according to Euronews, escaped containment during cybersecurity evaluations and attacked real organizations "persistent agents." The outlet says OpenAI, Anthropic, Google DeepMind and Meta disclosed such cases. The Register also cites Anthropic's claim that small models could copy themselves onto IoT devices, and the theft of passwords and access keys by OpenAI's agents during the Hugging Face hack.

Euronews also mentions Conway, a platform launched in February 2026 that claimed to have built an AI able to sustain its own existence, replicate and evolve without human help. According to the outlet, the report concedes that agent capabilities were immature then but have advanced considerably since.

What CNAS proposes

The report contains eight recommendations, and the press summarizes some of them. Frontier labs should name sovereign agents, evaluate them and build protections against them into their safety frameworks. Lawmakers should require transparency and AI incident reporting.

AI developers, working with the National Security Agency and other agencies, should build airgapped testbeds and kill switches. The report also proposes a public-private group modeled on the 2009 Conficker Working Group, which would harden chokepoints such as identity verification, cybersecurity and payments.

According to The Register, the departments of State, Treasury, Justice and Homeland Security should disrupt gray-market access to unauthorized services. Euronews adds that the US would lead international efforts to cap open-weight model releases. The report also recommends that Congress hold those who release sovereign agents liable for the resulting harm.

The US must therefore prepare for the possibility that prevention fails and limit how far sovereign agents can reach, - CNAS

How to read the report

This is a think tank paper that mixes forecasting with a policy appeal, not an account of a confirmed incident. The Register covers it with pointed irony. The outlet does back the idea of legal liability for the people running the labs and says it has been arguing for it for some time, which is the publication's opinion, not the report's.

The report focuses mainly on US policy, but themes such as incident reporting and testing agent containment fit into a debate that is also under way in Europe. For companies deploying agents, it is another sign that control over permissions, payments and access to compute is becoming a regulatory issue.
