一、前言
GLM-4是智谱AI团队于2024年1月16日发布的基座大模型，旨在自动理解和规划用户的复杂指令，并能调用网页浏览器。其功能包括数据分析、图表创建、PPT生成等，支持128K的上下文窗口，使其在长文本处理和精度召回方面表现优异，且在中文对齐能力上超过GPT-4。与之前的GLM系列产品相比，GLM-4在各项性能上提高了60%，并且在指令跟随和多模态功能上有显著强化，适合于多种应用场景。尽管在某些领域仍逊于国际一流模型，GLM-4的中文处理能力使其在国内大模型中占据领先地位。该模型的研发历程自2020年始，经过多次迭代和改进，最终构建出这一高性能的AI系统。

本篇将介绍如何集成vLLM进行推理加速。
二、术语
2.1.GLM-4-9B
是智谱 AI 推出的一个开源预训练模型，属于 GLM-4 系列。它于 2024 年 6 月 6 日发布，专为满足高效能语言理解和生成任务而设计，并支持最高 1M（约两百万字）的上下文输入。该模型拥有更强的基础能力，支持26种语言，并且在多模态能力上首次实现了显著进展。
GLM-4-9B的基础能力包括：
- 中英文综合性能提升 40%，在特别的中文对齐能力、指令遵从和工程代码等任务中显著增强
- 较 Llama 3 8B 的性能提升，尤其在数学问题解决和代码编写等复杂任务中表现优越
- 增强的函数调用能力，提升了 40% 的性能
- 支持多轮对话，还支持网页浏览、代码执行、自定义工具调用等高级功能，能够快速处理大量信息并给出高质量的回答
2.2.GLM-4-9B-Chat
是智谱 AI 在 GLM-4-9B 系列中推出的对话版本模型。它设计用于处理多轮对话，并具有一些高级功能，使其在自然语言处理任务中更加高效和灵活。
2.3.vLLM
vLLM是一个开源的大模型推理加速框架，通过PagedAttention高效地管理attention中缓存的张量，实现了比HuggingFace Transformers高14-24倍的吞吐量。
