开源模型应用落地-qwen1.5-7b-chat与sglang实现推理加速的正确姿势（一）

一、前言

** ** SGLang is a structured generation language designed for large language models (LLMs). It makes your interaction with LLMs faster and more controllable by co-designing the frontend language and the runtime system。简单来说就是，SGLang简化了LLM程序的编写并提高了执行效率，SGLang可以将常见的LLM任务加速高达5倍。

再看QWen官方描述：简单来说就是，QWen1.5系列模型也支持SGLang推理加速

二、术语介绍

**2.1. **SGLang

is a structured generation language designed for large language models (LLMs). It makes your interaction with LLMs faster and more controllable by co-designing the frontend language and the runtime system.

The core features of SGLang include:

• A Flexible Front-End Language: This allows for easy programming of LLM applications with
