# Fireworks AI

> [Fireworks AI](https://fireworks.ai) is a generative AI inference platform to run and
> customize models with industry-leading speed and production-readiness.

## Installation and setup

* Install the Fireworks integration package.

  ```bash theme={null}
  pip install langchain-fireworks
  ```

* Get a Fireworks API key by signing up at [fireworks.ai](https://fireworks.ai).

* Authenticate by setting the FIREWORKS\_API\_KEY environment variable.

### Authentication

There are two ways to authenticate using your Fireworks API key:

1. Setting the `FIREWORKS_API_KEY` environment variable.

   ```python theme={null}
   os.environ["FIREWORKS_API_KEY"] = "<KEY>"
   ```

2. Setting `api_key` field in the Fireworks LLM module.

   ```python theme={null}
   llm = Fireworks(api_key="<KEY>")
   ```
