A Fano-Style Accuracy Upper Bound for LLM Single-Pass Reasoning in Multi-Hop QA

ICLR 2026poster

Multi-Hop Question Answering (MHQA) requires integrating dispersed, interdependent evidence through sequential reasoning under noise. This task is challenging for LLMs as they have a finite per-pass output capacity, beyond which the integration of task-relevant evidence proves unreliable. Consequent…
