## Introduction: Proof-of-Coherence - A New Tool for Quantifying LLM Reasoning Consistency

This article introduces an open-source framework called Proof-of-Coherence, which aims to systematically observe and quantify the reasoning consistency of large language models (LLMs). By detecting self-contradictions of models on the same problem, it provides an auditable evaluation tool for AI safety research, filling the gap in traditional LLM evaluations that lack consistency measurement.

## Background: The Urgency of LLM Self-Contradiction Issues

LLMs perform well in various tasks, but the problem of self-contradiction has long plagued researchers: the same problem may yield inconsistent answers at different times or in different contexts. As LLMs are increasingly applied in high-risk scenarios such as medical diagnosis and legal consultation, such inconsistencies not only erode user trust but may also lead to serious consequences, making reliability a core concern.

## Project Overview: Core Objectives of Proof-of-Coherence

Proof-of-Coherence is an open-source LLM reasoning observatory, whose core objective is to quantify and prove model 'incoherence'. It provides a complete toolchain (auditable test artifacts, formal coherence metrics, public evaluation methods) to address the problem that traditional evaluations focus on accuracy while ignoring internal logical consistency.

## Core Mechanism: Key Components for Detecting Self-Contradictions

1. **Repetitive Query Mechanism**: Isolate context and query the same problem multiple times to simulate real scenarios;
2. **Semantic Comparison**: Identify opposing positions through semantic analysis rather than just string matching;
3. **Contradiction Classification**: Divided into four categories: position reversal, confidence drift, condition-dependent contradiction, time-sensitive contradiction;
4. **Coherence Score**: A 0-1 score to quantify model consistency, where 1 means fully coherent and 0 means completely contradictory.

## Practical Significance: Application Value for Multiple Roles

- **AI Safety Research**: Locate training data biases, model architecture flaws, and evaluate the effectiveness of fine-tuning and alignment techniques;
- **Model Developers**: Detect unstable areas before deployment to avoid contradictions in production environments;
- **End Users**: Need to confirm key issues multiple times, cross-verify, and maintain a skeptical attitude towards decisions.

## Technical Highlights and Limitations

**Technical Highlights**: Auditability (detailed logs can be independently verified), modular architecture (easy to extend algorithms/problem types), public transparency (open-source methodology);
**Limitations**: Semantic understanding has boundaries, some answers depend on unclear contexts, and current focus is on English model evaluation.

## Future Directions and Summary Thoughts

**Future Directions**: Multilingual detection, introducing human judgment as a gold standard, real-time consistency monitoring, combining with model uncertainty quantification;
**Summary**: This project marks a shift in LLM evaluation towards focusing on internal consistency, which is an essential path to building reliable AI systems. It reminds researchers to stay clear-headed about the limitations while marveling at the models' capabilities.
