# Petals

This page covers how to use the Petals ecosystem within LangChain. It is broken into two parts: installation and setup, and then references to specific Petals wrappers.

## Installation and Setup

- Install with `pip install petals`

- Get a Hugging Face api key and set it as an environment variable (`HUGGINGFACE_API_KEY`)

## Wrappers

### LLM

There exists an Petals LLM wrapper, which you can access with

    from langchain.llms import Petals
