arXiv 新书：推理配置如何影响推理模型的评测与部署结果

全书分三大块：评测环节讨论生成上限、答案抽取、评分方法和量化；复现环节解释为何即使关闭采样，输出仍会因 batch 组合、注意力后端和缓存不同而变化；服务环节覆盖 batching、显存容量、延迟、吞吐和成本。最后两章讲结构化输出、工具调用、推理预算和长上下文任务，并分析这些控制手段与基准各自能证明什么、不能证明什么。

书中给出可操作建议：记录推理运行参数、核查评测结果、估算服务容量、公平对比不同系统。对需要复现论文结果或做模型服务成本核算的工程师和研究者来说，这是一份直接可用的检查清单。

Inference for Reasoning Models: Practical Lessons from Evaluation and Serving

Running a language model involves more than its trained weights. The same model can receive very different benchmark scores, produce different answers, or cost more to serve depending on how it is evaluated and run. In one experiment in this book, changing only the maximum response length moved accuracy on a math benchmark from 0.08% to 93.18%. This book explains how inference settings shape the results we report and the systems we deploy. We begin with evaluation, including generation limits, answer extraction, scoring methods, and quantization. We then examine why outputs can change across batches, attention backends, and caching, even when sampling is disabled. The next chapters cover serving performance, including batching, memory capacity, latency, throughput, and cost. We also study structured outputs, tool calls, reasoning budgets, and long-context tasks, showing what these controls and benchmarks do and do not establish. The book concludes with practical guidance for recording inference runs, checking evaluations, estimating capacity, and comparing systems fairly. Written for researchers and engineers working with language models, it aims to make inference results easier to understand, reproduce, and trust.
