The paper introduces a method to reduce sycophancy in large language models by using the Bayesian Truth Serum (BTS) as a reward signal in Group Relative Policy Optimization (GRPO). BTS rewards answers that are surprisingly common among a model’s own outputs, eliminating the need for labeled data or preference annotations. Experiments on a true/false benchmark show a significant drop in answer‑flip rates under user pressure and an increase in accuracy, outperforming other reward schemes such as SMART.

A new study shows that conformal certificates can become invalid when a large language model (LLM) is influenced by peers who unanimously provide a wrong answer, even though the question itself remains unchanged. This phenomenon, termed a score‑mechanism shift, reveals that a model’s calibration for single‑agent scoring does not hold in multi‑agent settings, leading to a drop in coverage from 90% to 74% under unanimous‑wrong peers. The shift also allows attackers to target low‑confidence items, nearly halving coverage for that subgroup while keeping overall averages deceptively high, and can cause systems to act confidently on incorrect answers.
