New paper details LLM uncertainty sources and effective quantification methods

A new paper introduces a detailed taxonomy for understanding uncertainty in Large Language Models (LLMs), breaking it down into input, parameter, token, and decoding-process sources. The research categorizes existing Uncertainty Quantification (UQ) methods and proposes a comprehensive evaluation framework. Experiments across Qwen3, Llama 3.2, and DeepSeek-V3 models show that consensus-based UQ methods like Deg and EigV are most effective, and that larger model scales generally correlate with lower uncertainty.
