What Sets FLUX 3 Image Apart
Box-based composition puts you in charge of placement — choose a ratio, draw your frames, and let a single scene line finish the picture.
- Precise Box PlacementDraw a frame around each object you care about, then tell the generator what should appear inside it.
- Any Ratio, One 0–1000 GridReshape the canvas freely — both axes stay on a 0 to 1000 scale, so your box coordinates never lose meaning.
- A Single Line Unifies the SceneOne scene description pulls every framed element into a coherent whole, just like the Le Festival du Soleil example.
Three Steps to Your FLUX 3 Image
From a blank canvas to a fully composed picture in three simple moves.
FLUX 3 Image: Common Questions
Short answers on composing a FLUX 3 Image with boxes, canvas ratios and a scene line.
How do boxes decide where objects appear?
Every frame you draw marks the region that a specific element will occupy, so the described object is rendered inside that area.
What is the 0–1000 canvas grid for?
Both axes of the canvas are measured on a 0 to 1000 scale, whichever ratio you choose, so every box position is expressed on a consistent scale.
Must I pick a ratio before placing boxes?
Yes. The ratio comes first, and since both axes always run 0 to 1000, the same coordinates stay readable when you switch to another canvas shape.
What role does the scene prompt play?
It is the single line that connects your individual boxes into one coherent image — as in the 'Le Festival du Soleil' example, rendered from boxes plus a scene line.
Can I describe every box on its own?
Absolutely. After drawing a frame you write what belongs inside it, so each region carries its own content instruction.
Is a subscription or seat licence required?
No. Pricing is pay as you go — no subscriptions and no seat fees, you are only charged for what you generate, and open-weights licensing tiers exist for running the models on your own infrastructure.
