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
