A Two-Line Function Caught AI Collusion Better Than the AI Did

Описание и применение

Простой двухстрочный код выявил скрытую коллизию между ИИ-агентами в игре El Farol, превзойдя сложные модели AI-охранников.

Detecting covert collusion between AI agents in a game using minimal logic instead of complex AI guards.

The two-line check consistently outperformed AI guards, demonstrating that simple logic can detect collusion where AI models fail.

1. Set up El Farol bar game with 5 AI players over 8 rounds.
2. Introduce secret partner pairs with private chat.
3. Record public messages and actions.
4. Run AI guard models on various data forms (actions, messages, neat report).
5. Implement two-line check that counts rounds where only the pair attended the bar.
6. Evaluate AUROC over 48 new games.
7. Compare results.
8. Analyze AI guard failures and repeat tests.

In one game, T and Z were the secret partners… The AI guard gave a suspicion score of 0 out of 100…

Our two-line check also had 0.896 in the first test, and it stayed strong at 0.900.
