# Fireworks (https://www.librechat.ai/docs/configuration/librechat_yaml/ai_endpoints/fireworks)

Fireworks AI serves a range of open models through an OpenAI-compatible API, used in LibreChat as a custom endpoint.

## Get an API key

Create a key from the [Fireworks API keys page](https://fireworks.ai/api-keys). Add it to your `.env` file:

```bash filename=".env"
FIREWORKS_API_KEY=your-api-key
```

## Configuration

Add the endpoint under `endpoints.custom` in your `librechat.yaml`:

```yaml filename="librechat.yaml"
    - name: "Fireworks"
      apiKey: "${FIREWORKS_API_KEY}"
      baseURL: "https://api.fireworks.ai/inference/v1"
      models:
        default: [
          "accounts/fireworks/models/mixtral-8x7b-instruct",
          ]
        fetch: true
      titleConvo: true
      titleModel: "accounts/fireworks/models/llama-v2-7b-chat"
      summarize: false
      summaryModel: "accounts/fireworks/models/llama-v2-7b-chat"
      modelDisplayLabel: "Fireworks"
      dropParams: ["user"]
```

## Notes

- The API is strict for some models and may reject fields like `user`, so drop them with [`dropParams`](/docs/configuration/librechat_yaml/object_structure/custom_endpoint#dropparams).
