01 · Overview
What is FLUX 3 Image?
FLUX 3 is the model the Klein line was distilled from — the full-weight flagship with the deepest prompt understanding in the FLUX family. It holds complex scenes together: multiple subjects, precise spatial relations, and the kind of lighting that makes a render read as a photograph.
Five tiers: 768px at 6 credits, 1K at 7, 1.5K at 10, 2K at 14, and a 4K tier at 81 credits for the rare job that needs sixteen megapixels. Edits cost the same as generations at every tier, with up to ten references. New accounts start with 20 free credits: three 768px images.

Good to know: the 4K tier is priced for the rare job that genuinely needs sixteen megapixels — it costs about six times the 2K tier and can take several minutes. For almost everything, 2K at 14 credits is the sweet spot. The lightweight sibling is FLUX 3 Klein (from 2 credits).

Why creators pick FLUX 3 Image
Ten references, one price
FLUX 3 takes up to ten reference images — the most of any FLUX model — and charges the same as a fresh generation for the edit. Mood boards, character sheets and multi-angle product sets all fit in a single job.
The 768px sketch tier
Not every idea needs a megapixel. The 768px tier renders the full flagship's understanding at 6 credits — explore compositions cheaply, then re-render the winner at 1K or 2K.

Wide storybook scenes
“A tiny lighthouse on a floating island with waterfalls, pastel sky, storybook style”
The floating lighthouse at 16:9 — the flagship holds the impossible geography together: the island floats, the waterfalls fall, the pastel sky stays pastel.

Prompt guide
- Draft at 768px: 6 credits buys the flagship's full understanding at sketch size — explore here, finish at 2K.
- Use all ten references: FLUX 3 charges nothing extra for them, so bring the whole mood board.
- Reserve 4K for print: at 81 credits it is a deliberate purchase — large-format print, hero billboards, heavy crops. Everything else belongs at 2K.
- Klein for volume: FLUX 3 Klein is the distilled sibling from 2 credits — same family, lighter weight, faster answers.
