About FLUX Dev
FLUX Dev is the 12-billion-parameter middle child of the FLUX line — more detail and tighter prompt-following than the free Schnell, without the price of 1.1 Pro. At 1 credit it’s the sensible step up.
Unlike Schnell’s four steps, Dev runs the full denoise (28 steps here), so it holds finer detail and handles busy, multi-part prompts more gracefully.
Reach for it when the free output isn’t quite cutting it but the job doesn’t need top-end Pro polish.
