# AI21 Labs

This page covers how to use the AI21 ecosystem within LangChain.
It is broken into two parts: installation and setup, and then references to specific AI21 wrappers.

## Installation and Setup
- Get an AI21 api key and set it as an environment variable (`AI21_API_KEY`)

## Wrappers

### LLM

There exists an AI21 LLM wrapper, which you can access with 
```python
from langchain.llms import AI21
```
Docs refactor (#480) Big docs refactor! Motivation is to make it easier for people to find resources they are looking for. To accomplish this, there are now three main sections: - Getting Started: steps for getting started, walking through most core functionality - Modules: these are different modules of functionality that langchain provides. Each part here has a "getting started", "how to", "key concepts" and "reference" section (except in a few select cases where it didnt easily fit). - Use Cases: this is to separate use cases (like summarization, question answering, evaluation, etc) from the modules, and provide a different entry point to the code base. There is also a full reference section, as well as extra resources (glossary, gallery, etc) Co-authored-by: Shreya Rajpal <ShreyaR@users.noreply.github.com> 2023-01-02 16:24:09 +00:00			`# AI21 Labs`
