SGLang is an open-source, high-performance serving framework designed for fast and scalable inference of large language and multimodal models.

SGLang provides a production-grade inference solution for LLMs and VLMs, enabling reliable, low-latency, and high-throughput serving from a single GPU to distributed clusters. It incorporates advanced optimizations like disaggregated prefill/decode, speculative decoding, and a zero-overhead scheduler to maximize performance across diverse hardware and models.

Key Features

High-performance, scalable inference for LLMs and VLMs
Production-grade serving for large-scale deployments
Broad model and hardware flexibility (NVIDIA, AMD, CPU, TPU, Ascend)
Advanced optimizations (disaggregated prefill/decode, speculative decoding)
OpenAI-compatible API endpoints

Pros

Significantly improves LLM/VLM inference speed and scalability
Supports a wide range of models and hardware platforms
Open-source with an active community
Easy to install and deploy with pip or Docker

Cons

Requires technical expertise for setup and management
Focuses on serving, not model training or development

Use Cases
