OpenClaw ships a bundled fal provider for hosted image, video, and music 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; Krea 2: 1 per request
Edit modeFlux: 1 reference image; GPT Image 2: 10; Nano Banana 2: 14
Style refsKrea 2: up to 10 style references via image / images
Size overridesSupported
Aspect ratioSupported for generate, Krea 2, 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. Nano Banana 2 also accepts extra-native wide/tall ratios such as 4:1, 1:4, 8:1, and 1:8; Krea 2 validates its own smaller aspect-ratio subset.
Krea 2 models use fal’s native Krea payload schema. OpenClaw sends aspect_ratio, creativity, and image_style_references instead of the generic image_size / edit-endpoint payload used by Flux. The model refs are:
  • fal/krea/v2/medium/text-to-image
  • fal/krea/v2/large/text-to-image
Use Medium for faster expressive illustration, anime, painting, and artistic styles. Use Large for slower photoreal, raw texture, film grain, and detailed looks. Krea defaults to fal.creativity: "medium"; supported values are raw, low, medium, and high. Krea 2 exposes aspect ratio, not image_size, in fal’s request schema. Prefer aspectRatio; OpenClaw maps size to the closest supported Krea aspect ratio and rejects resolution for Krea rather than dropping it. Use outputFormat: "png" when you want PNG output from fal models that expose output_format. fal does not declare an explicit transparent-background control in OpenClaw, so background: "transparent" is reported as an ignored override for fal models. Krea 2 endpoints do not expose an output_format request field through fal, so OpenClaw rejects outputFormat overrides for Krea requests. To use fal as the default image provider: 
{
  agents: {
    defaults: {
      imageGenerationModel: {
        primary: "fal/fal-ai/flux/dev",
      },
    },
  },
}
To use Krea 2 Medium: 
{
  agents: {
    defaults: {
      imageGenerationModel: {
        primary: "fal/krea/v2/medium/text-to-image",
      },
    },
  },
}

​
Video generation

The bundled fal video-generation provider defaults to fal/fal-ai/minimax/video-01-live.
CapabilityValue
ModesText-to-video, single-image reference, Seedance reference-to-video
RuntimeQueue-backed submit/status/result flow for long-running jobs
HeyGen video-agent:
  • fal/fal-ai/heygen/v2/video-agent
Seedance 2.0:
  • fal/bytedance/seedance-2.0/fast/text-to-video
  • fal/bytedance/seedance-2.0/fast/image-to-video
  • fal/bytedance/seedance-2.0/fast/reference-to-video
  • fal/bytedance/seedance-2.0/text-to-video
  • fal/bytedance/seedance-2.0/image-to-video
  • fal/bytedance/seedance-2.0/reference-to-video
{
  agents: {
    defaults: {
      videoGenerationModel: {
        primary: "fal/bytedance/seedance-2.0/fast/text-to-video",
      },
    },
  },
}

{
  agents: {
    defaults: {
      videoGenerationModel: {
        primary: "fal/bytedance/seedance-2.0/fast/reference-to-video",
      },
    },
  },
}
Reference-to-video accepts up to 9 images, 3 videos, and 3 audio references through the shared video_generate images, videos, and audioRefs parameters, with at most 12 total reference files.
{
  agents: {
    defaults: {
      videoGenerationModel: {
        primary: "fal/fal-ai/heygen/v2/video-agent",
      },
    },
  },
}

​
Music generation

The bundled fal plugin also registers a music-generation provider for the shared music_generate tool.
CapabilityValue
Default modelfal/fal-ai/minimax-music/v2.6
Modelsfal-ai/minimax-music/v2.6, fal-ai/ace-step/prompt-to-audio, fal-ai/stable-audio-25/text-to-audio
RuntimeSynchronous request plus generated audio download
Use fal as the default music provider: 
{
  agents: {
    defaults: {
      musicGenerationModel: {
        primary: "fal/fal-ai/minimax-music/v2.6",
      },
    },
  },
}
fal-ai/minimax-music/v2.6 supports explicit lyrics and instrumental mode. ACE-Step and Stable Audio are prompt-to-audio endpoints; choose them with the model override when you want those model families.
