Uncertainty Decomposition for Clarification Seeking in LLM Agents

arXiv:2606.19559v1 Announce Type: cross Abstract: Recent position papers argue that the classical aleatoric/epistemic uncertainty framework is insufficient for interactive large language model (LLM) agents and call for underspecification-aware, decomposed, and communicable uncertainty representations that can unlock new agent capabilities such as proactive clarification seeking and shared mental-model building. Practical deployment constraints -- black-box APIs, interactive latency budgets, and the absence of labeled trajectories -- rule out logprob-based, multi-sampling, and training-based me

Why this matters
Why now

The rapid advancement and deployment of large language models are exposing their limitations in interactive, real-world agentic applications, necessitating better uncertainty management for practical deployment.

Why it’s important

Improved uncertainty decomposition and clarification seeking in LLM agents will enhance their reliability, autonomy, and ability to handle complex tasks, accelerating their integration into automated workflows.
