📝 摘要(中文)
大型推理模型(LRMs)生成的长推理轨迹揭示了中间推理行为,为研究和控制AI编码中的推理提供了机会。然而,这些轨迹中的潜在模式及其对编码模型分析和指导的可能性仍然不够清晰,限制了LRM推理的系统性表征和推理时控制。本文通过对四个代表性编码任务的推理模式进行实证研究,将推理轨迹转化为结构化的动作序列,并利用任务内支持、任务间对比和有效-无效支持对比挖掘重复片段。我们对编码代理的四种一般推理模式进行了表征:从设计到实现的代码生成、执行推理的状态追踪、调试的证据-修复-重检和翻译的语义映射。我们进一步识别了与有效和无效推理轨迹相关的正负模式,正模式反映了基于验证的收敛,而负模式则反映了重复的设计修订、反思和知识回忆而无结论。为展示其实用性,我们评估了三种基于模式的应用:任务识别、模式引导提示和模式感知早停。

📄 摘要(原文)
Large Reasoning Models (LRMs) generate long reasoning traces that expose intermediate inference behavior, offering opportunities to study and control reasoning in AI coding. However, the underlying patterns in these traces and their potential for analyzing and guiding coding models remain poorly understood, limiting systematic characterization and inference-time control of LRM reasoning. We conduct an empirical study of reasoning patterns across four representative coding tasks. We transform reasoning traces into structured action sequences and mine recurring fragments using within-task support, cross-task contrasts, and valid--invalid support contrasts. We characterize four general reasoning patterns by coding agents: design-to-implementation for code generation, state tracing for execution reasoning, evidence--fix--recheck for debugging, and semantic mapping for translation. We further identify positive and negative patterns associated with valid and invalid reasoning traces, respectively. Positive patterns reflect verification-driven convergence, whereas negative patterns reflect repeated design revision, reflection, and knowledge recall without closure. To demonstrate their practical utility, we evaluate three pattern-based applications: task identification, pattern-guided prompting, and pattern-aware early stopping. Features capturing general reasoning patterns enable accurate task identification from reasoning traces without accessing task descriptions or final answers. Prompting guided by positive and negative patterns improves the overall accuracy of downstream tasks, while negative pattern-aware early stopping substantially reduces API-reported token usage with only a modest decrease in pass@1. All three applications also generalize to previously unseen models, showing that reasoning patterns can support both the analysis and control of LRM behavior in AI coding.
