Input Schema

11 parameters · 2 required · 9 optional

Parameter	Type	Required	Description
`image`	string	Required	URL of image to use for image-to-image generation.
`prompt`	string	Required	The prompt to generate an image from.
`seed`	integer	Optional	The same seed and the same prompt given to the same version of the model will output the same image every time.
`loras`	object[]	Optional	The LoRAs to use for the image generation. You can use any number of LoRAs and they will be merged together to generate the final image. · Default: []
`aspect_ratio`	string	Optional	The aspect ratio of the generated image. · Options: 21:9, 16:9, 3:2, 4:3, 5:4, 1:1, 4:5, 3:4, 2:3, 9:16 21:916:93:24:35:41:14:53:42:39:16
`output_format`	string	Optional	The format of the generated image. · Options: jpeg, png · Default: "jpeg" jpegpng
`guidance_scale`	number	Optional	The CFG (Classifier Free Guidance) scale is a measure of how close you want the model to stick to your prompt when looking for a related image to show you. · Min: 0 · Max: 35 · Default: 3.5
`preprocess_depth`	boolean	Optional	If set to true, the input image will be preprocessed to extract depth information. This is useful for generating depth maps from images. · Default: true
`num_inference_steps`	integer	Optional	The number of inference steps to perform. · Min: 1 · Max: 50 · Default: 28
`control_lora_strength`	number	Optional	The strength of the control lora. · Min: 0 · Max: 2 · Default: 1
`control_lora_image_url`	string	Optional	The image to use for control lora. This is used to control the style of the generated image.

Output Schema

Field	Type	Description
`id`	string	Unique identifier for the generation task
`status`	string	Task status: pending, running, completed, failed, timeout
`model`	string	Model used for the generation
`outputs`	array	Array of output items
`outputs[].url`	string	URL of the generated artifact
`outputs[].content_type`	string	MIME type (e.g. image/png, video/mp4)
`error`	object \| null	Error details if failed, null on success
`error.type`	string	Machine-readable error type code
`error.message`	string	Human-readable error description

Async Workflow

This model uses asynchronous execution. Submit a request and poll for the result.

Submit — POST to /v1/run, receive an id
Poll — GET /v1/run/{id} until status is completed, failed, or timeout
Retrieve — Read outputs from the completed response
