Image generation

Image guide

Generate and edit images with Flux 2. Both actions draw from the same hourly image budget.

⏳ Generation is synchronous — do not refresh or close the page until the image appears (flux2-klein-9b ~12-25s, flux2-dev ~70-150s).

📝 Edit (no mask) — the model regenerates the WHOLE image, using your reference as a style/identity hint. Good for "same object, new scene".

🎨 Inpaint (toggle "Draw mask" + paint an area) — only the painted region is regenerated; everything outside the mask is preserved pixel-perfect. Good for "remove this object", "replace the background", "add something here".

Inpaint mask — paint where to change Draw mask

Brush 60 Drag = paint · Right-click drag = erase

Advanced mask settings

These tune HOW the regenerated region blends with the rest of the picture. They do NOT change WHAT is painted; they shape the boundary between painted and preserved areas. Defaults (0/0) mean "exactly as drawn, sharp edges".

Soft edge 0 px

Blurs the boundary so the new content fades into the preserved area instead of snapping to the brush stroke.

Show examples

0 px — sharp boundary (default). Best when the new region has clear edges (a logo, a sign, replacing a flat-color background).
8-15 px — light blend. Use when adding a NEW object that should look planted in the scene without a halo.
20-30 px — heavy blend. Use for atmospheric changes (relighting, sky / fog) where the transition should be invisible.

Expand area 0 px

Grows or shrinks the mask after you've drawn it, without re-painting.

Show examples

0 px — exactly as you painted (default).
+5 to +15 — covers small bits you missed at the edge of the object you're removing or replacing.
+20 and up — also catches shadows or reflections of the object you're removing.
-5 to -10 — pulls the mask inward; useful if your strokes accidentally crossed onto something you wanted to keep.
