Input

Field	Kind	Default	Description
`prompt` required	text	—	The prompt to edit the image.
`image_url` required	URL or file	—	The URL of the image to edit. Max width: 14142px, Max height: 14142px, Timeout: 20s
`num_inference_steps`	number (whole) 10 to 50	28	The number of inference steps to perform.
`seed`	number (whole)	—	The same seed and the same prompt given to the same version of the model will output the same image every time.
`guidance_scale`	number 1 to 20	2.5	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.
`num_images`	number (whole) 1 to 4	1	The number of images to generate.
`output_format`	one of jpeg, png	jpeg	Output format
`acceleration`	one of none, regular, high	none	The speed of the generation. The higher the speed, the faster the generation.
`resolution_mode`	one of auto, match_input, 1:1, 16:9, 21:9, 3:2, 2:3, 4:5, 5:4, 3:4, 4:3, 9:16, 9:21	match_input	Determines how the output resolution is set for image editing. - `auto`: The model selects an optimal resolution from a predefined set that best matches the input image's aspect ratio. This is the recommended setting for most use cases as it's what the model was trained on. - `match_input`: The model will attempt to use the same resolution as the input image. The resolution will be adjusted to be compatible with the model's requirements (e.g. dimensions must be multiples of 16 and within supported limits). Apart from these, a few aspect ratios are also supported.
