How to order

This is the image-to-image twin of flux2-pro-text-to-image: create the series with that id in model and attach reference images — the service switches to this model by itself. Its own id is not accepted in a series.

Model parameters

What the model itself understands; the ordering calls above take their own fields and pass these on.

Name	Type	Required	Description
`input_urls`	array	required	Input reference images (1-8 images). (File URL after upload, not file content; Accepted types: image/jpeg, image/png, image/webp; Max size: 10.0MB)
`prompt`	string	required	Must be between 3 and 5000 characters. (Max length: 5000 characters)
`aspect_ratio`	string	required	Aspect ratio for the generated image. Select 'auto' to match the first input image ratio (requires input image). Values: `1:1`, `4:3`, `3:4`, `16:9`, `9:16`, `3:2`, `2:3`, `auto` Default: `1:1`
`resolution`	string	required	Output image resolution. Values: `1K`, `2K` Default: `1K`
`nsfw_checker`	boolean	optional	Defaults to false. You can set it to false based on your needs. If set to false, our content filtering will be disabled, and all results will be returned directly by the model itself. Note: There is no guarantee that everything can be filtered out; if you are not satisfied with the results, you will need to make your own arrangements.
