•required

Prompt that guides image generation.

•required image_url
Drop a file, or

URL pointing to the image that will be relit.

image_size

Dimensions of the generated image.

num_images default 1

Image count requested for generation.

default

Negative prompt specifying unwanted image content.

Drop a file, or

Mask URL for the ic-light conditioning image.

initial_latent default None

Lighting conditions supplied to the model.

output_format default jpeg

File format for the resulting image.

default 0.67

Deprecated background-removal threshold with no current effect on results. Its intended behavior is to sharpen masks at higher settings.

default 28

Count of inference steps to run.

default 1

Actual classifier-free guidance scale applied during generation.

default 0.98

Strength applied during the low-resolution pass.

default 0.95

Strength applied during the high-resolution pass; takes effect only when enable_hr_fix is True.

default 0.5
default 5

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

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

About IC-Light-v2 for Image Relighting

Takes a source image (`image_url`) and a `prompt` describing the desired lighting and background. `initial_latent` can set the light direction (Left, Right, Top, Bottom), and an optional `mask_image_url` conditions the result. Offers `enable_hr_fix` for a high-resolution pass, 1-4 outputs via `num_images`, and jpeg or png output.

Parameters

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