About Kolors

Generates images from a text `prompt`, with optional `negative_prompt`. You can tune `guidance_scale` (1 to 10), `num_inference_steps` (1 to 150) and pick a `scheduler` from six options. Produces 1 to 8 images per call in six preset sizes, as png or jpeg, with `seed` for repeatability.

Parameters

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