FLUX 3 Image is now on Leonardo.Ai

You can now make 4K images with FLUX 3 Image, Black Forest Labs' image model, in the Leonardo.Ai image generator. Pick Large size, up to 5456 × 3072 at 16:9, then zoom in: the small details stay sharp at full size.

Zoom in on every detail

On the FLUX 3 Image page, see one Large image beside a close crop of it, down to the chipped paint and the grain of the wood.

Frame it wide at 21:9

Choose from 15 aspect ratios, from tall 9:21 to wide 21:9. At 21:9, a Large image is 6256 × 2688. See a 21:9 example on the FLUX 3 Image page.

Edit an image and keep what matters

Pick an image to edit and add it as an image reference. Then say what to change and what to keep. You can add up to 10 image references to each generation, and they don't add to the cost. Compare an original with its edit on the FLUX 3 Image page.

What you get

• Up to 10 image references in each generation, at no extra cost
• Up to 8 images from one prompt
• 15 aspect ratios, from 9:21 to 21:9

Start your first 4K image

Pick Large size, then say what's in the shot, where it is and how it's lit. The cost depends on the size and the number of images, and the generation panel shows it before you generate.
