Flux Dev vs Flux Schnell
FLUX.1 Dev against FLUX.1 Schnell for fast background and prop generation.
Every value below is read from the model catalog at generation time — price and which parameters each model exposes. 2 of the 13 spec rows differ between these two. “Not exposed” means the model has no API parameter for it — it does not mean the capability is absent. A model without a transparent-background switch can still produce a clean white background from a prompt; it just cannot hand you an alpha channel.
