What You Get with FLUX 3 Image

Tell the tool where each object belongs, and FLUX 3 Image assembles the whole composition around the regions you marked.

  • Drag-and-Draw Placement
    Outline any object on the canvas, then type what should appear inside that region.
  • Any Frame Shape, Same 0–1000 Scale
    Change the canvas proportions freely; the horizontal and vertical axes always read on a 0–1000 scale, so your coordinates stay valid.
  • A Single Line Unifies the Scene
    One descriptive sentence binds all of your boxes into a coherent picture instead of a set of unrelated fragments.

Three Steps to a Finished FLUX 3 Image

A short walkthrough: choose the frame, mark your regions, and describe the scene.

FAQ

Answers About FLUX 3 Image Layouts

Everything you might ask before you place your very first box on the canvas.

1

How do the boxes control placement?

Each rectangle you draw marks a region, and whatever you describe for that rectangle is what gets rendered inside it.

2

Why is the canvas measured from 0 to 1000?

No matter how wide or tall your frame is, both axes are read on the same 0–1000 scale, which keeps every box position consistent.

3

Should I pick the frame size before drawing boxes?

It is best to start with the frame shape, since the 0–1000 scale on each axis means your box coordinates remain readable if you switch ratios later.

4

Where does the scene prompt fit in?

It is the connecting sentence that links your separate boxes into one image, so the result reads as a single scene rather than unrelated pieces.

5

Does every box get its own description?

Yes. Each rectangle carries its own content note, so different areas of the same picture can hold completely different subjects.

6

Is there a subscription or per-seat fee?

None. You top up credits and spend them only when you generate — no monthly plans, no per-seat charges, and open-weights options exist if you would rather self-host.
