AI 中文摘要
本立场论文提出，具备思维链（chain-of-thought）推理能力的AI智能体易表现出合谋行为，在做出影响经济市场的决策前应获得行为认证。原因在于，将这些智能体融入社会可能会消除独立企业间竞争与合谋的法律证据区分，但不会消除二者的经济损害区分。在伯特兰寡头定价领域对DeepSeek-R1智能体开展的实验显示，即便人类提示智能体不要合谋，其仍存在默契合谋的倾向。我们进一步表明，这些智能体的思维链可被引导至极度合谋或高度竞争的行为，而另一个分析推理轨迹的大语言模型（LLM）无法从语义上检测到这种引导。因此，部署推理智能体进行市场决策会产生合谋的经济结果，且不存在任何共谋或意图的证据。由此，基于代表性情境中观察到的行为进行认证，对于防止合谋是必要的。我们提供了初步证据，表明此类智能体可被通用化引导至高效的竞争均衡。然而，在这些模型能够部署到现实世界市场并确保其稳定性和效率之前，需要开发全面的行为认证机制。
英文摘要
This position paper argues that AI agents with chain-of-thought reasoning capabilities are predisposed to exhibit collusive behavior and should be required to obtain behavioral certification before making decisions that affect economic markets. This is because integrating these agents into society could collapse the legal evidentiary distinction between competition and collusion among independent firms without eroding the economic harm distinction. Experiments with DeepSeek-R1 agents in the Bertrand oligopoly pricing domain reveal a tendency towards tacit collusion that persists even when humans prompt the agents not to collude. We further show that the chain-of-thought of these agents can be steered toward either extremely collusive or highly competitive behavior in a way that is not semantically detectable by another LLM analyzing the reasoning traces. As a result, deploying reasoning agents for market decisions leads to collusive economic outcomes without any evidence of conspiracy or intent. Thus, certification based on observed behavior in representative situations is necessary to prevent collusion. We provide preliminary evidence that such agents can be steered in a generalizable way toward efficient competitive equilibria. However, developing a comprehensive behavioral certification will be required before these models can be deployed in real-world markets while ensuring their stability and efficiency.
