Let LLMs Judge Each Other: Multi-Agent Peer-Reviewed Reasoning for Medical Question Answering
arXiv:2606.15419v1 Announce Type: new Abstract: Objective: To enhance the accuracy, interpretability, and robustness of large language models (LLMs) in medical question answering (MedQA). Method: We designed a multi-agent peer-reviewed reasoning method in which multiple LLM agents independently generate chain-of-thought reasoning with candidate answers, then act as peer reviewers to evaluate each other's reasoning for factual correctness and logical soundness. The highest-rated reasoning chain is selected to produce the final answer. Experiments were conducted with five state-of-the-art LLMs (
The development of more sophisticated AI agents for specialized domains like medicine is a natural evolution as LLM capabilities mature.
This development indicates a significant step towards more reliable and autonomous AI in critical applications, reducing the need for direct human oversight in certain analytical tasks.
LLMs can now be configured to self-critique and improve their reasoning, leading to higher accuracy and robustness without constant iterative human feedback for every response.
