This page demonstrates how to use Xinference with LangChain. Xinference is a powerful and versatile library designed to serve LLMs, speech recognition models, and multimodal models, even on your laptop. With Xorbits Inference, you can effortlessly deploy and serve your or state-of-the-art built-in models using just a single command.

Installation and Setup

Xinference can be installed via pip from PyPI:

LLM

Xinference supports various models compatible with GGML, including chatglm, baichuan, whisper, vicuna, and orca. To view the builtin models, run the command:

Wrapper for Xinference

You can start a local instance of Xinference by running:
You can also deploy Xinference in a distributed cluster. To do so, first start an Xinference supervisor on the server you want to run it:
Then, start the Xinference workers on each of the other servers where you want to run them on:
You can also start a local instance of Xinference by running:
Once Xinference is running, an endpoint will be accessible for model management via CLI or Xinference client. For local deployment, the endpoint will be http://localhost:9997. For cluster deployment, the endpoint will be http://${supervisor_host}:9997. Then, you need to launch a model. You can specify the model names and other attributes including model_size_in_billions and quantization. You can use command line interface (CLI) to do it. For example,
A model uid will be returned. Example usage:
