Researchers explored whether a language model's own token probabilities could indicate when its reasoning is flawed. In multi-agent debates, the confidence of the initial tokens generated showed a correlation with judged reasoning quality, even predicting critical failures with an AUROC up to 0.85. However, the effectiveness and direction of this statistic varied across different datasets, suggesting that a fixed rule would be unreliable and recalibration per dataset is necessary for a cheap screening method.
