SGLang: Fast Serving Framework for Language Models
Overview
SGLang is an open-source framework designed for efficient interaction with large language models (LLMs) and vision language models. By co-designing the backend runtime and frontend language, SGLang streamlines model interactions, making them faster and more controllable.
Key Features
- Fast Backend Runtime: SGLang utilizes innovative techniques like RadixAttention for prefix caching, overhead-free CPU scheduling, and tensor parallelism, ensuring efficient model serving.
- Flexible Frontend Language: The intuitive interface allows for advanced prompting, control flow, multi-modal inputs, and parallelism, making it easy to develop LLM applications.
- Extensive Model Support: Compatible with various generative models (e.g., Llama, Mistral) and embedding models, SGLang facilitates easy integration of new models.
How to Use
Getting started with SGLang is simple:
- Installation: Follow the quick start guide to set up SGLang.
- Sending Requests: Utilize the backend tutorials for OpenAI APIs and native APIs to begin interacting with models.
Benefits for Users
- High Performance: With features like continuous batching and quantization, users experience rapid response times.
- Community Support: Being open-source, SGLang benefits from an active community, providing resources and support for users.
Alternatives
While SGLang is robust, alternatives like Hugging Face Transformers and OpenAI's API offer different functionalities that may suit specific needs.
