Researchers have developed MARGIN, a new online calibration method designed to improve the trustworthiness of foundation model agents in multi-agent systems. Unlike traditional methods that require model access and fixed datasets, MARGIN learns calibration factors directly from the task stream in real-time, without retraining or held-out data. Experiments across 19 models and 8 benchmarks demonstrated that MARGIN significantly reduces calibration error under distribution shift and enhances the ability of a coordinator to select the most accurate agent response, outperforming random chance and even the best-performing single model in some cases.
