What You Get with FLUX 3 Image
Compose the frame deliberately: boxes mark where things sit, the ratio sets the shape, and one line describes the whole scene.
- Draw-Your-Own CompositionSketch a rectangle around every subject you care about, then tell the tool what belongs inside that region.
- Any Ratio, Same 0–1000 CoordinatesSwitch between portrait, landscape or square — coordinates still run 0 to 1000 on both axes, so your boxes stay put.
- A Single Line Unifies the SceneOne short scene description blends all of your labelled regions into a coherent finished picture.

FLUX 3 Image: Common Questions
Short answers on drawing boxes, picking ratios and generating with FLUX 3 Image.
How does a bounding box control placement?
Each rectangle you draw marks the area reserved for one element, so the tool knows where that described subject should appear.
What is the 0–1000 canvas grid?
Both axes are measured from 0 to 1000 no matter the frame shape, which keeps every box position on one consistent scale.
Should I pick an aspect ratio first?
Yes. Choose the ratio before drawing, and because coordinates always span 0 to 1000, the same numbers remain meaningful if you change the shape.
What role does the scene prompt play?
It is a single sentence that pulls your separate regions into one coherent image, giving the whole composition a shared setting and mood.
Can I describe every box on its own?
Absolutely. Every rectangle accepts its own instruction, so each area can hold a different subject, colour or object.
Do I need a subscription or a seat licence?
No. You pay only for the generations you run — no subscriptions, no seat fees — and open-weights tiers are available if you prefer to host the models yourself.
