OpenClaw ships a bundled fal provider for hosted image and video generation.
PropertyValue
Providerfal
AuthFAL_KEY (canonical; FAL_API_KEY also works as a fallback)
APIfal model endpoints

​
Getting started

1

Set the API key

openclaw onboard --auth-choice fal-api-key
2

Set a default image model

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

​
Image generation

The bundled fal image-generation provider defaults to fal/fal-ai/flux/dev.
CapabilityValue
Max images4 per request
Edit modeFlux: 1 reference image; GPT Image 2: 10; Nano Banana 2: 14
Size overridesSupported
Aspect ratioSupported for generate and GPT Image 2/Nano Banana 2 edit
ResolutionSupported
Output formatpng or jpeg
Flux image-to-image requests do not support aspectRatio overrides. GPT Image 2 and Nano Banana 2 edit requests use fal’s /edit endpoint and accept aspect-ratio hints.
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: 
{
  agents: {
    defaults: {
      imageGenerationModel: {
        primary: "fal/fal-ai/flux/dev",
      },
    },
  },
}

​

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

    defaults: {
      videoGenerationModel: {
        primary: "fal/bytedance/seedance-2.0/fast/text-to-video",
      },

}
