arXiv:2606.03969v1 Announce Type: new Abstract: Reliable uncertainty communication is critical to the trustworthiness of LLMs, yet faithful calibration (FC)--the alignment between models' intrinsic and (linguistically) expressed confidence--is a persistent failure mode. This challenge is key for large reasoning models (LRMs), whose extended reasoning traces are often interpreted by users as evidence of deliberation, competence, and confidence. Despite the importance of FC and wide usage of LRMs, the extent to which LRMs can faithfully express their confidence remains poorly understood. Moreove
As Large Reasoning Models (LRMs) become more sophisticated and are integrated into critical applications, the need for reliable uncertainty communication and faithful calibration becomes paramount for their trustworthiness and adoption.
Faithful confidence expression is critical for users to correctly interpret LRM outputs, particularly in high-stakes environments, directly impacting the reliability and trustworthiness of AI applications.
The ability to quantify and potentially improve Faithful Calibration (FC) in LRMs suggests a pathway to more robust and transparent AI systems, shifting the perception of AI reliability.
