arXiv:2607.03870v1 Announce Type: new Abstract: As LLMs generate increasingly long outputs, effective uncertainty estimation must identify errors at fine-grained levels rather than discard entire responses. While such methods exist, evaluating uncertainty at any resolution (token to an entire generation) is challenging and highly sensitive to label imperfections, making zero-noise benchmarks essential; yet, long-form generation benchmarks tend to rely on fallible labels rather than deterministic ground truth. We introduce Single-answer Atomic Long-form Target (SALT), a benchmark of six procedu
The rapid development and deployment of LLMs for longer-form content generation necessitates better methods for evaluating their reliability and trustworthiness.
Accurate uncertainty estimation in long-form LLM outputs is crucial for their adoption in critical applications, impacting enterprise trust and AI safety significantly.
The introduction of SALT provides a robust, deterministic benchmark for evaluating LLM uncertainty, addressing a key limitation of existing benchmarks that rely on fallible labels.
