Dimensions of the generated image.

num_images default 1

Image count requested for generation.

default []
Drop a file, or

Image URLs supplying generation references; the syntax <img><|image_1|></img> identifies entry one, with successive image numbers identifying later entries.

output_format default jpeg

File format for the resulting image.

default 50

Count of inference steps to run.

default 3

Prompt-adherence strength for image selection, expressed as CFG (Classifier Free Guidance).

default 1.6

Image guidance scale specifying the desired resemblance between the input image and the related image the model selects for display.

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

About OmniGen v1

Generates images from a `prompt` and optional `input_image_urls`, which are referenced in the text with <img><|image_1|></img> style tags. It covers editing, personalized generation and virtual try-on. Controls include six `image_size` presets, `guidance_scale`, `img_guidance_scale`, up to 50 steps and up to 4 images in jpeg or png.

Parameters

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