代码解释器(CI)推理已成为增强大型语言模型(LLMs)推理能力的有效范式,通过可执行计算和迭代验证来实现。尽管其应用日益广泛,但有效代码推理的行为特性仍未得到充分探索。本文从外在特性(关键标记)和内在特性(代码特定认知行为)两个角度研究代码推理。研究发现,强大的CI推理模型在关键标记和认知行为(如验证、回溯和反向链)方面表现更为突出。通过在推理和训练中利用这些特性,发现添加代码特定关键标记能提升数学、排序和优化等推理能力,而在训练中增强模型则能改善监督微调和强化学习的表现。研究首次系统性地表征了CI推理的有效性,揭示了其潜力与局限性。

📄 摘要(原文)
Reasoning with a Code Interpreter (CI) has emerged as an effective paradigm for enhancing the reasoning capabilities of large language models (LLMs) through executable computation and iterative verification. Despite its growing adoption, the behavioral properties underlying effective code reasoning remain largely underexplored. In this work, we investigate code reasoning from two distinct perspectives inspired by prior studies of natural language reasoning: extrinsic properties, represented by crucial tokens, and intrinsic properties, represented by code-specific cognitive behaviors. Across multiple LLMs, we find that stronger CI reasoning models consistently exhibit a higher prevalence of crucial tokens and cognitive behaviors, particularly verification, backtracking, and backward chaining. Building on these observations, we examine how these properties can be leveraged during both inference and training. At inference time, appending code-specific crucial tokens improves performance on several reasoning capabilities, including mathematical, ordering, and optimization, while yielding limited benefits elsewhere. At training time, augmenting a state-of-the-art framework with code-specific cognitive behaviors improves supervised fine-tuning and reinforcement learning performance in two of three evaluated models. Further analysis shows that these behaviors reduce overthinking in incorrect responses and improve token efficiency, while also revealing factors that limit gains in a certain model. Our findings provide the first systematic characterization of effective reasoning with CI and demonstrate both the potential and limitations of leveraging key properties to improve CI-based reasoning.
