Designers who need exact control over layout get grid-based composition and 4K output, though the 4K tier costs about 60 cents an image.

Kenning's take

What it does

FLUX 3 Image is the image side of Black Forest Labs FLUX 3. It can lay out a picture from bounding boxes on a grid, each with its own description, or work from a plain prompt. It also makes multi-turn edits that leave untouched areas unchanged, accepts up to 10 reference images and outputs up to 4K, through the paid BFL API.

  • Bounding-box layout control
  • Pixel-preserving multi-turn edits
  • Up to 10 reference images
  • Output up to 4K
  • Text-to-image prompting

Who it suits. Designers and developers who need tight control over image composition.
