•required

Image generation or editing instructions, best expressed specifically—for example, 'Add the bird from image 1 to the desk in image 2'.

image_size default square_hd

Dimensions of the generated image.

num_images default 1

Image count requested for generation.

default (((deformed))), blurr...

Negative prompt describing content to exclude from the image.

default []
Drop a file, or

Up to 3 image URLs supplying source images for editing or generation from multiple images.

scheduler default euler

Scheduler used during diffusion.

output_format default jpeg

File format for the resulting image.

default 50

Count of inference steps to run.

default 5

Text guidance scale: increase it to strengthen the generated image's adherence to the text prompt.

default 2

Image guidance scale, with 1.3–2.0 for editing and 2.0–3.0 for in-context generation, determines the strength of adherence to the supplied images.

default 0

Starting value of the CFG range.

default 1

Ending value of the CFG range.

Seed for reproducible images: an identical prompt and seed produce an identical image when the model version is unchanged.

About Omnigen V2

A multimodal image model that creates or edits images from a `prompt` and up to 3 `input_image_urls`. It exposes `text_guidance_scale` (1 to 8), `image_guidance_scale` (1 to 3), CFG range start and end, a `negative_prompt`, and a choice of `euler` or `dpmsolver` scheduler. Steps run from 20 to 50, with up to 4 outputs.

Parameters

Send either the canonical name or the native name, not both. Canonical names
