Inference-Time Conformal Reasoning with Valid Factuality Control for Large Language Models

arXiv:2606.08831v1 Announce Type: new Abstract: Large language models (LLMs) increasingly perform multi-step reasoning, where intermediate claims form implicit directed acyclic graphs whose node correctness is structurally conditioned on their ancestors. This makes factuality uncertainty structural, rather than a trivial accumulation of node-wise errors, and necessitates inference-time uncertainty quantification over the reasoning structure. While conformal prediction (CP) offers flexible user-specified factuality control, existing work remains post-hoc and cannot intervene during generation.

Why this matters
Why now

The increasing complexity of LLM reasoning chains necessitates improved factuality control to enable reliable multi-step autonomous operations.

Why it’s important

Achieving valid factuality control during inference is crucial for the deployment of truly autonomous AI agents across sensitive domains, mitigating risks of hallucination and unreliable outputs.

What changes

The proposed method introduces a way to dynamically intervene during LLM generation to ensure factual accuracy, moving beyond post-hoc corrections.
