vLLM: Serve language model answers to applications
Added · Updated
Made by vLLM
View profile on GitHub (opens in a new tab)Run supported language models and serve their answers to applications with a model-serving library for developers.
What it does
vLLM is a library that runs language models to generate answers and makes those models available to applications. It groups incoming requests for processing and can send text as it is generated. Its server offers interfaces that applications can use to request answers, including structured results.
How to use it
Install the library with uv or pip, then follow the repository's linked quickstart to try a supported model. This is a developer installation; vLLM has no browser demo or desktop app.
Common use cases
- Send prompts from an application to a supported model and receive generated text through the server.
- Request a structured response from a supported model and receive output in the requested structure.
- Send a generation request and display the answer progressively as text arrives.
Can I use this?
Requirements Choose a supported model and consult the installation guide for your hardware. The source lists supported processors and graphics hardware, but not how much memory a particular model needs.
Caveat Check the model and hardware documentation before choosing a setup.
