# Hazy Research

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

## Installation and Setup

- To use the `manifest`, install it with `pip install manifest-ml`

## Wrappers

### LLM

There exists an LLM wrapper around Hazy Research’s `manifest` library. `manifest` is a python library which is itself a wrapper around many model providers, and adds in caching, history, and more.

To use this wrapper:

    from langchain.llms.manifest import ManifestWrapper
