FLUX 3 Image: Common Questions
Straight answers on box placement, canvas grids and pricing for FLUX 3 Image.
How do the boxes decide where objects land?
Each rectangle you draw reserves a region for that object, so the renderer knows precisely where the described element should appear.
What is the 0–1000 grid actually for?
Both axes are always scored from 0 to 1000, so the same pair of coordinates points to the same spot no matter how the canvas is shaped.
Should I pick a ratio before drawing boxes?
Yes. Setting the frame first keeps your coordinates meaningful, because the 0 to 1000 scale is unaffected by the canvas proportions.
Why does the scene prompt matter?
It is the single line that pulls your separate boxes into one coherent picture, giving the whole frame a shared mood, setting and lighting.
Can I describe every box on its own?
Absolutely. After drawing a rectangle you type what belongs inside it, so each region carries its own separate content instruction.
Is a subscription or seat licence required?
No. You pay only for what you generate — there are no subscriptions and no per-seat charges, and open-weight options exist for self-hosting.
