## [Introduction] SGLang: A High-Performance Inference Service Framework for Large Language Models

SGLang is a high-performance inference service framework designed specifically for large language models (LLMs) and multimodal models. Its core goal is to address bottlenecks such as high latency and low throughput in model deployment. Targeting production environments, this framework optimizes GPU resource utilization through an innovative architecture, supports multimodal services, and is actively developed as an open-source project, making it suitable for scenarios like enterprise-level real-time request processing.

## Project Background and Motivation

With the rapid development of LLMs and multimodal models, efficient deployment services have become a core challenge in the AI field. Traditional inference frameworks face issues of high latency and low throughput under high-concurrency requests, directly affecting user experience and system costs. The SGLang project emerged to provide a new solution through innovative architectural design.

## Core Positioning and Technical Objectives

SGLang is positioned as a high-performance inference service framework for production environments, different from research-oriented projects, focusing on performance optimization in actual deployment. Its core objectives include reducing inference latency, improving concurrent processing capability, optimizing GPU resource utilization, simplifying the service process for multimodal models, and being suitable for enterprise-level real-time request processing scenarios.

## Technical Architecture Features

SGLang adopts an efficient batch processing mechanism to intelligently merge requests and improve GPU utilization rate; it supports dynamic batch processing, automatically adjusting batch size based on load to balance latency and throughput; it is optimized for multimodal models, capable of handling multiple input types such as text and images simultaneously, adapting to the development needs of multimodal AI.

## Performance Optimization Strategies

SGLang reduces GPU memory allocation and release overhead through fine-grained memory pool design and caching strategies; it supports continuous batch processing, allowing new requests to join immediately after existing batches are completed without waiting for a new batch, significantly reducing average response time—especially effective when requests arrive irregularly.
