Why people pick Flux Schnell
Sub-2-second outputs
Distilled 4-step inference. Flux Schnell is the fastest production-quality model in the Flux family — fast enough to keep up with a live brainstorm.
~$0.005 per image
1 credit per image. Schnell is the cheapest hosted Flux online. Generate 50 variations to find the one, then upgrade the winner to Pro.
Compositions land on the first try
Schnell isn't the most detailed Flux, but it nails layout and style far more often than other 'fast' models — making it the right backend for iteration and prototyping.

FAQ
Common questions
Is Flux Schnell free?+
Each new account gets 50 free credits — enough for 50 Schnell images. After that, Schnell stays at 1 credit (~$0.005) per image. There's no free tier with unlimited use, but the per-image cost is essentially noise.
Why is Schnell so much cheaper than other models?+
Schnell uses a distilled 4-step schedule instead of the standard 25+ steps. Same model weights family, much less compute per image. We pass the cost saving through.
Will Schnell quality be enough for my use case?+
For social, blog headers, moodboards, prototyping, and concept work — almost always. For polished hero shots and editorial work, use Flux Dev or 1.1 Pro instead.
Can I switch from Schnell to Pro mid-session?+
Yes. The model picker is one click inside Studio — your prompt and reference images carry over.
