ChatFireworks
=============

You can use models provided by Fireworks AI as follows:

tip

See [this section for general instructions on installing integration packages](/v0.2/docs/how_to/installation#installing-integration-packages).

*   npm
*   Yarn
*   pnpm

    npm install @langchain/community

    yarn add @langchain/community

    pnpm add @langchain/community

tip

We're unifying model params across all packages. We now suggest using `model` instead of `modelName`, and `apiKey` for API keys.

    import { ChatFireworks } from "@langchain/community/chat_models/fireworks";const model = new ChatFireworks({  temperature: 0.9,  // In Node.js defaults to process.env.FIREWORKS_API_KEY  apiKey: "YOUR-API-KEY",});

#### API Reference:

*   [ChatFireworks](https://v02.api.js.langchain.com/classes/langchain_community_chat_models_fireworks.ChatFireworks.html) from `@langchain/community/chat_models/fireworks`

Behind the scenes, Fireworks AI uses the OpenAI SDK and OpenAI compatible API, with some caveats:

*   Certain properties are not supported by the Fireworks API, see [here](https://readme.fireworks.ai/docs/openai-compatibility#api-compatibility).
*   Generation using multiple prompts is not supported.
