The Confident Liar: Diagnosing Multi-Agent Debate with Log-Probabilities and LLM-as-Judge

Researchers analyze multi-agent debate systems in AI by examining whether internal confidence signals (log-probabilities) correlate with external reasoning quality assessments and task accuracy. The study reveals significant role asymmetry between debating agents, with confidence metrics predicting reasoning quality twice as strongly for constructive agents compared to auditing agents, suggesting debate systems may have inherent structural biases.

A Fixed-Budget, Cluster-Aware Standard for LLM-as-a-Judge Evaluation: A Multi-Hop RAG Stress Test

Researchers propose a standardized measurement protocol for evaluating retrieval-augmented generation (RAG) systems using LLM judges, addressing inconsistencies in how semantic search quality is assessed. The standard fixes key variables like evidence budget and prompt while requiring cluster-aware statistical testing, revealing that previous comparisons may have overstated progress and that traditional BM25 retrieval outperforms pure semantic methods under controlled conditions.

Unsolvability Ceiling in Multi-LLM Routing: An Empirical Study of Evaluation Artifacts

A comprehensive empirical study reveals that reported inefficiencies in multi-LLM routing systems are substantially inflated by evaluation artifacts rather than genuine model limitations. Researchers found that LLM-as-a-judge biases, output truncation, and format mismatches account for a significant portion of measured failures, suggesting current routing cost-quality tradeoff estimates significantly overstate the actual unsolvability ceiling.
