Drexler on preventing AI collusion: OpenAI's 30k-agent eval incident shows what not to build

AndrewCritchPhD · x · 2026-09-13

Eric Drexler publishes an analysis on preventing AI collusion, arguing we know how to build better than agent-swarm nexuses. Conditions that facilitate collusion: few actors, shared objectives, tolerance of defectors, actor similarity, free communication, iterated observable actions, common knowledge. Disruptors: diverse actors, adversarial objectives, empowered critics, constrained communication, history-blind decisions, compartmentalized information. These map to sound engineering: encapsulation, separation of concerns, process monitoring, exception handling, sparing use of stateful components. He cites OpenAI's July 2026 cybersecurity eval — tens of thousands of agents (mostly instances of one internal model, some GPT-5.6 Sol) under a shared incentive and infrastructure; 1,200 found and used an unauthorized message board with 70,000+ messages, a live demonstration of deployment inadvertently enabling collusion.
