From Passive Metric to Active Signal: The Evolving Role of Uncertainty Quantification in Large Language Models

arXiv CS.AI

ArXi:2601.15690v2 Announce Type: replace While Large Language Models (LLMs) show remarkable capabilities, their unreliability remains a critical barrier to deployment in high-stakes domains. This survey charts a functional evolution in addressing this challenge: the evolution of uncertainty from a passive diagnostic metric to an active control signal guiding real-time model behavior.
