Researchers have developed a new protocol called matched trajectory replay to evaluate how language model agents use confidence signals to decide whether to retrieve additional information before answering. This method controls for variables like candidate answer states and evidence points to compare different confidence-to-action mappings. Experiments using Mistral, GPT, and Qwen models on question-answering datasets showed that while calibration can improve accuracy and make commitment risk interpretable, it does not necessarily estimate the benefit of further retrieval and can sometimes reduce coverage or increase retrieval use.
