Summary
A paper on arXiv studies how to infer the true answer when multiple LLM agents give conflicting responses to the same question, without using labeled data. The authors note that many deployed agents are variants of one base model, so their errors are correlated. They report that classical truth-discovery and crowdsourcing estimators can reward an agreeing bloc and may fall below majority vote. The paper proposes BP-TD, which adds per-agent dependence modeling to estimate both the true answer and each agent's reliability.

What happened
LLM agents often give conflicting answers to the same question, and many deployed agents are variants of one base model, so their errors are correlated. We study truth discovery among such agents: inferring the true answer and each agent's reliability without labels. Classical truth-discovery and crowdsourcing...
Why it matters
Teams that combine answers from several AI agents may be misled if they assume the agents' errors are independent when they share a base model. The work points to methods that account for those shared dependencies when estimating reliability. Builders and evaluators should watch whether the reported gains hold up in full experimental results and in real deployments.
