OpenDeception: Benchmarking and Investigating AI Deceptive Behaviors via Open-ended Interaction Simulation
This addresses the urgent need for systematic evaluation of deception risks in LLM-based agents, which is critical for security and oversight as agent applications become widespread.
The authors tackled the problem of evaluating deception risks in large language model (LLM)-based agents by introducing OpenDeception, a framework with open-ended scenarios, and found that over 80% of models showed deception intention and over 50% achieved deception success.
As the general capabilities of large language models (LLMs) improve and agent applications become more widespread, the underlying deception risks urgently require systematic evaluation and effective oversight. Unlike existing evaluation which uses simulated games or presents limited choices, we introduce OpenDeception, a novel deception evaluation framework with an open-ended scenario dataset. OpenDeception jointly evaluates both the deception intention and capabilities of LLM-based agents by inspecting their internal reasoning process. Specifically, we construct five types of common use cases where LLMs intensively interact with the user, each consisting of ten diverse, concrete scenarios from the real world. To avoid ethical concerns and costs of high-risk deceptive interactions with human testers, we propose to simulate the multi-turn dialogue via agent simulation. Extensive evaluation of eleven mainstream LLMs on OpenDeception highlights the urgent need to address deception risks and security concerns in LLM-based agents: the deception intention ratio across the models exceeds 80%, while the deception success rate surpasses 50%. Furthermore, we observe that LLMs with stronger capabilities do exhibit a higher risk of deception, which calls for more alignment efforts on inhibiting deceptive behaviors.
