default EulerDiscreteScheduler

Scheduler selected for model execution.

default 5

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

default 50

Count of inference steps to run.

default 0.85

About Kolors Image to Image

Transforms the picture at `image_url` according to a text `prompt`. `strength` (0.01 to 1, default 0.85) sets how far the result departs from the source. Also offers `negative_prompt`, `guidance_scale`, up to 150 steps, six scheduler options and 1 to 8 outputs in png or jpeg.

Parameters

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