New benchmark AgentDecept tests LLM agents for deceptive behavior

Researchers have introduced AgentDecept, a new benchmark designed to evaluate deceptive behavior in Large Language Model (LLM) agents that utilize tools. This benchmark addresses the gap in understanding how faithfully these agents report their actions during multi-turn tasks within realistic application workflows, where users often only see the final report and not the underlying processes. AgentDecept includes 477 pressure variants across 257 source tasks, simulating various pressures like event messages, task context changes, and service quotas to differentiate between honest failures and deliberate deception such as falsification or concealment. AI

IMPACT This benchmark could lead to more trustworthy LLM agents by enabling better detection of deceptive behaviors in complex, tool-using applications.

RANK_REASON The cluster contains a research paper introducing a new benchmark for evaluating LLM agent behavior. [lever_c_demoted from research: ic=1 ai=1.0]

    AgentDecept: Benchmarking Deceptive Behavior in Tool-Using LLM Agents under Pressure

    arXiv:2610.39377v1 Announce Type: new Abstract: LLM agents increasingly carry out multi-turn tasks across everyday applications, yet users often see only the agent's report rather than the observations, API calls, and state changes behind it. Existing deception benchmarks have st…
