📝 摘要(中文)

近年来,大型语言模型(LLMs)在复杂推理能力上取得了显著进展。然而,现有研究对这些模型推理过程和输出的系统比较仍显不足,尤其是在自我反思模式及跨领域关联性方面。本文提出了一种新颖的框架,通过关键词统计和LLM作为评判者的范式,分析四种前沿推理模型(GPT-o1、DeepSeek-R1、Kimi-k1.5和Grok-3)的推理特征。研究结果揭示了这些模型在推理过程中如何平衡探索与利用、处理问题及得出结论的多种模式,并通过定量和定性比较,识别出模型间在推理深度、对中间步骤的依赖程度及思维过程与输出模式的相似性等方面的差异。该研究为提高模型设计和评估提供了实用建议。

🔬 方法详解

问题定义:本文旨在解决对大型推理语言模型推理过程和输出的系统比较不足的问题,现有方法未能深入探讨模型的自我反思模式和跨领域关联性。

核心思路:提出一种新颖的分析框架,通过关键词统计和LLM作为评判者的方式,连接模型的内部思维过程与最终输出,提供更全面的比较视角。

技术框架:整体架构包括数据集构建、模型推理过程分析和输出评估三个主要模块。数据集涵盖逻辑推理、因果推断和多步骤问题解决的真实场景问题。

关键创新:最重要的创新在于提出了一套新的评估指标,能够量化推理的连贯性和输出的准确性,揭示模型在推理过程中的探索与利用平衡。

关键设计:在参数设置上,采用了多种评估指标来衡量模型的推理深度和输出准确性,设计了特定的损失函数以优化模型的推理能力。整体网络结构则基于现有的推理模型进行改进,增强其对中间步骤的依赖性。

📄 摘要(原文)

Recently, there have been notable advancements in large language models (LLMs), demonstrating their growing abilities in complex reasoning. However, existing research largely overlooks a thorough and systematic comparison of these models' reasoning processes and outputs, particularly regarding their self-reflection pattern (also termed "Aha moment") and the interconnections across diverse domains. This paper proposes a novel framework for analyzing the reasoning characteristics of four cutting-edge large reasoning models (GPT-o1, DeepSeek-R1, Kimi-k1.5, and Grok-3) using keywords statistic and LLM-as-a-judge paradigm. Our approach connects their internal thinking processes with their final outputs. A diverse dataset consists of real-world scenario-based questions covering logical deduction, causal inference, and multi-step problem-solving. Additionally, a set of metrics is put forward to assess both the coherence of reasoning and the accuracy of the outputs. The research results uncover various patterns of how these models balance exploration and exploitation, deal with problems, and reach conclusions during the reasoning process. Through quantitative and qualitative comparisons, disparities among these models are identified in aspects such as the depth of reasoning, the reliance on intermediate steps, and the degree of similarity between their thinking processes and output patterns and those of GPT-o1. This work offers valuable insights into the trade-off between computational efficiency and reasoning robustness and provides practical recommendations for enhancing model design and evaluation in practical applications.
