arXiv:2603.24967v2 Announce Type: replace Abstract: Understanding why a large language model (LLM) is uncertain about the response is important for their reliable deployment. Current approaches, which either provide a single uncertainty score or rely on the classical aleatoric-epistemic dichotomy, fail to offer actionable insights for improving the generative model. Recent studies have also shown that such methods are not enough for understanding uncertainty in LLMs. In this work, we advocate for an uncertainty decomposition framework that dissects LLM uncertainty into three distinct semantic
The rapid deployment of LLMs into critical applications necessitates a more nuanced understanding of their reliability, moving beyond simplistic uncertainty metrics.
A strategic reader needs to understand the foundational limits and mechanisms of LLM uncertainty to properly assess risks and opportunities in AI deployment.
The proposed 'uncertainty decomposition framework' moves beyond current, insufficient methods, enabling more actionable insights for improving LLM reliability and performance.
