LLM research tackles uncertainty in function calls and system propagation

By PulseAugur Editorial · Summary by gemini-2.5-flash-lite from 2 sources

Two new research papers explore the critical issue of uncertainty in Large Language Models (LLMs). The first paper investigates uncertainty quantification methods specifically for LLM function-calling, finding that simple single-sample methods can be effective and can be improved by analyzing output structure. The second paper addresses uncertainty propagation within complex LLM-based systems, proposing a framework to understand how errors can compound across various system components and processes. AI

    Uncertainty Quantification for LLM Function-Calling

    arXiv:2604.22985v1 Announce Type: new Abstract: Large Language Models (LLMs) are increasingly deployed to autonomously solve real-world tasks. A key ingredient for this is the LLM Function-Calling paradigm, a widely used approach for equipping LLMs with tool-use capabilities. How…

    Uncertainty Propagation in LLM-Based Systems

    arXiv:2604.23505v1 Announce Type: cross Abstract: Uncertainty in large language model (LLM)-based systems is often studied at the level of a single model output, yet deployed LLM applications are compound systems in which uncertainty is transformed and reused across model interna…
