---

OpenClaw ships a bundled `fal` provider for hosted image and video generation.

| Property | Value                                                         |
| -------- | ------------------------------------------------------------- |
| Provider | `fal`                                                         |
| Auth     | `FAL_KEY` (canonical; `FAL_API_KEY` also works as a fallback) |
| API      | fal model endpoints                                           |

## Getting started

<Steps>
  <Step title="Set the API key">
    ```bash
    openclaw onboard --auth-choice fal-api-key
    ```
  </Step>
  <Step title="Set a default image model">
    ```json5
    {
      agents: {
        defaults: {
          imageGenerationModel: {
            primary: "fal/fal-ai/flux/dev",
          },
        },
      },
    }
    ```
  </Step>
</Steps>

## Image generation

The bundled `fal` image-generation provider defaults to
`fal/fal-ai/flux/dev`.

| Capability     | Value                      |
| -------------- | -------------------------- |
| Max images     | 4 per request              |
| Edit mode      | Enabled, 1 reference image |
| Size overrides | Supported                  |
| Aspect ratio   | Supported                  |
| Resolution     | Supported                  |
| Output format  | `png` or `jpeg`            |

<Warning>
The fal image edit endpoint does **not** support `aspectRatio` overrides.
</Warning>

Use `outputFormat: "png"` when you want PNG output. fal does not declare an
explicit transparent-background control in OpenClaw, so `background:
"transparent"` is reported as an ignored override for fal models.

To use fal as the default image provider:

```json5
{
  agents: {
    defaults: {
      imageGenerationModel: {
        primary: "fal/fal-ai/flux/dev",
      },
    },
  },
}
```

## Video generation

The bundled `fal` video-generation provider defaults to
`fal/fal-ai/minimax/video-01-live`.

| Capability | Value                                                              |
| ---------- | ------------------------------------------------------------------ |
| Modes      | Text-to-video, single-image reference, Seedance reference-to-video |
| Runtime    | Queue-backed submit/status/result flow for long-running jobs       |
