arXiv:2603.25450v2 Announce Type: replace Abstract: Detecting when a language model is wrong without ground truth labels is a fundamental challenge for safe deployment. Existing approaches rely on a model's own uncertainty -- such as token entropy or confidence scores -- but these signals fail critically on the most dangerous failure mode: confident errors, where a model is wrong but certain. In this work we introduce cross-model disagreement as a correctness indicator -- a simple, training-free signal that can be dropped into existing production systems, routing pipelines, and deployment moni
The rapid deployment of large language models necessitates robust methods for error detection without reliance on ground truth, especially as models are integrated into critical systems.
This development offers a practical, training-free method to enhance the safety and reliability of AI systems by identifying confident errors, mitigating a significant barrier to broader AI adoption.
AI developers and deployers now have a new, accessible tool for real-time model trustworthiness assessment, transcending previous limitations of internal uncertainty signals.
