About Seedream 4.5
Seedream 4.5 generates and edits images with the same ByteDance model, in what fal describes as a unified architecture, at a flat $0.10 per image. It runs as text to image and edit with references. Output is 2K and 4K, in 1:1, 4:3, 3:4, 16:9, 9:16, 3:2 and 2:3, and edits take up to 10 reference images.
The price is the same at every resolution and shape, $0.10, and grows only with the number of images: $0.40 for the largest batch. A typical generation takes about 25 s.
Good for
- Large images at 4K for the same price as 2K
- Edits that keep a subject consistent across up to 10 reference images
Getting good results
- Resolution does not change the price here, so pick 4K whenever the bigger file is useful: every image costs $0.10.
- Set a seed, under Advanced, to get the same result again from the same prompt.
