📝 摘要（中文）
Shojaee等人（2025）提出的研究揭示了大型推理模型（LRMs）在特定复杂性阈值以上性能崩溃的现象，称为推理崖。本文评论认为这一结论受到实验伪影的影响，实际反映的是系统级约束下的执行问题，而非认知能力的根本性限制。通过实验证明，模型在使用代理工具后能够解决原本无法解决的复杂问题，展示了代理推理的层次性，强调了工具在机器智能定义中的重要性。
🔬 方法详解
问题定义：本文旨在解决大型推理模型在复杂性阈值以上性能崩溃的问题，现有方法未能充分考虑系统级约束和实验设计的影响。
核心思路：通过引入代理间隙的概念，强调模型在执行时的限制，认为推理能力并非根本性缺陷，而是缺乏有效工具的结果。
技术框架：研究通过对比文本生成与工具使用的模型性能，分析模型在不同复杂性下的表现，主要模块包括文本生成、工具使用和性能评估。
关键创新：提出代理间隙的概念，强调模型在执行能力上的局限性，与现有方法的根本区别在于关注执行环境而非单纯的推理能力。
关键设计：实验中使用了o4-mini和GPT-4o等工具启用模型，设计了多种复杂性的问题，并对模型的输出进行了详细的统计分析。通过对比不同模型在工具使用前后的表现，揭示了代理推理的层次性。
📊 实验亮点
实验结果显示，使用代理工具后，模型在解决复杂问题时的表现显著提升，能够处理超出推理崖的复杂性，展示了代理推理的层次性和能力的逆转，强调了工具在模型智能中的重要性。
🎯 应用场景
该研究的潜在应用领域包括智能助手、自动化决策系统和复杂问题求解等。通过提升模型的执行能力，可以在实际应用中更有效地解决复杂任务，推动人工智能在各个领域的应用与发展。
📄 摘要（原文）
The recent work by Shojaee et al. (2025), titled The Illusion of Thinking: Understanding the Strengths and Limitations of Reasoning Models via the Lens of Problem Complexity, presents a compelling empirical finding, a reasoning cliff, where the performance of Large Reasoning Models (LRMs) collapses beyond a specific complexity threshold, which the authors posit as an intrinsic scaling limitation of Chain-of-Thought (CoT) reasoning. This commentary, while acknowledging the study's methodological rigor, contends that this conclusion is confounded by experimental artifacts. We argue that the observed failure is not evidence of a fundamental cognitive boundary, but rather a predictable outcome of system-level constraints in the static, text-only evaluation paradigm, including tool use restrictions, context window recall issues, the absence of crucial cognitive baselines, inadequate statistical reporting, and output generation limits. We reframe this performance collapse through the lens of an agentic gap, asserting that the models are not failing at reasoning, but at execution within a profoundly restrictive interface. We empirically substantiate this critique by demonstrating a striking reversal. A model, initially declaring a puzzle impossible when confined to text-only generation, now employs agentic tools to not only solve it but also master variations of complexity far beyond the reasoning cliff it previously failed to surmount. Additionally, our empirical analysis of tool-enabled models like o4-mini and GPT-4o reveals a hierarchy of agentic reasoning, from simple procedural execution to complex meta-cognitive self-correction, which has significant implications for how we define and measure machine intelligence. The illusion of thinking attributed to LRMs is less a reasoning deficit and more a consequence of an otherwise capable mind lacking the tools for action.
