# Cohere

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

## Installation and Setup

- Install the Python SDK with `pip install cohere`

- Get an Cohere api key and set it as an environment variable (`COHERE_API_KEY`)

## Wrappers

### LLM

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

    from langchain.llms import Cohere

### Embeddings

There exists an Cohere Embeddings wrapper, which you can access with

    from langchain.embeddings import CohereEmbeddings
