摘要

最近在arXiv上发表的一项研究探讨了大型语言模型（LLMs）的推理过程，重点关注推理步骤中的冗余概念。研究表明，这些模型进行的相当一部分推理可以安全地截断，而不会影响最终答案的准确性。具体而言，研究结果表明冗余水平可以显著变化，范围从61%到93%。这表明，过度的思考不仅是特定模型的缺陷，而是当前LLMs设计中固有的共同特征。

A recent study published on arXiv delves into the reasoning processes of large language models (LLMs), focusing on the concept of redundancy in their reasoning steps. The research reveals that a substantial portion of the reasoning performed by these models can be safely truncated without impacting the accuracy of their final answers. Specifically, the findings indicate that redundancy levels can vary significantly, ranging from 61% to 93%. This suggests that excessive deliberation is not merely a flaw of specific models but rather a common characteristic inherent in the design of current LLMs.

    How Much Thinking is Enough? Quantifying and Understanding Redundancy in LLM Reasoning

    The paper quantifies and analyzes the redundancy in reasoning processes of large language models (LLMs), revealing that a significant portion of their reasoning steps can be truncated without affecting the final answer. The study shows that redundancy levels can reach between 61% and 93%, indicating that excessive deliberation is a structural characteristic of current reasoning models rather than an individual model flaw.
