Getting Started

Please give us a star before you begin, and you'll receive instant notifications for every new release on GitHub!

Jupyter Notebook

The lightest way to experience Xinference is to try our Juypter Notebook on Google Colab.


Nvidia GPU users can start Xinference server using Xinference Docker Image. Prior to executing the installation command, ensure that both Docker and CUDA are set up on your system.

docker run --name xinference -d -p 9997:9997 -e XINFERENCE_HOME=/data -v </on/your/host>:/data --gpus all xprobe/xinference:latest xinference-local -H

Quick Start

Install Xinference by using pip as follows. (For more options, see Installation page.)

pip install "xinference[all]"

To start a local instance of Xinference, run the following command:

$ xinference-local

Once Xinference is running, there are multiple ways you can try it: via the web UI, via cURL, via the command line, or via the Xinference’s python client. Check out our docs for the guide.
