arXiv:2606.17312v1 Announce Type: new Abstract: Large language models can arrive at the same answer through reasoning paths that are unstable, contradictory, or difficult to rank consistently -- a failure mode especially prevalent in multi-step deductive reasoning. Existing methods assess reliability primarily through output dispersion -- measuring how much sampled answers differ -- but this discards a complementary signal: whether the model can consistently rank competing reasoning candidates. We propose structural uncertainty, a consistency-aware framework derived from the stability of self-
The rapid advancement and deployment of large language models are exposing critical limitations in their logical reasoning consistency, necessitating new evaluation frameworks.
Improving the reliability and consistency of LLMs is paramount for their safe and effective integration into sensitive applications, particularly those requiring multi-step deductive reasoning.
The focus for LLM development will shift partly towards ensuring internal consistency and stability of reasoning paths, rather than solely on output accuracy.

- · Developers of interpretability tools for AI
- · LLM developers prioritizing raw output without deep internal consistency checks
- · Sectors relying on black-box, unreliable LLM reasoning
New evaluation metrics and benchmarks for LLM consistency will emerge, becoming standard for model deployment.
Enterprise adoption of LLMs for complex reasoning tasks accelerates as trust in their underlying logic improves.
More robust, verifiable AI agents capable of explaining their reasoning and identifying inconsistencies become viable, transforming high-stakes decision-making workflows.
