About FLUX.1 [schnell]

A distilled 12-billion-parameter FLUX model that needs only 1 to 4 denoising steps, which makes it the quickest way to turn a prompt into an image. Use it for drafts, thumbnails, previews and high-volume pipelines; switch to a larger FLUX model when fine detail or exact lettering matters. Any size up to 14 megapixels, up to four images per request.
