Seedream image models on HFLUX
Two of them: 5.0 Pro and 5.0 Lite. Pro carries two things no other image model here has — it can hand a picture back in separate stacked pieces, and it can edit one marked spot rather than the whole frame.
Credits per image
| Model | 1K | 1.5K | 2K | 3K | 4K |
|---|---|---|---|---|---|
| Seedream 5.0 Pro | 12 | 12 | 24 | — | — |
| Seedream 5.0 Pro · layers | 6 | 6 | 12 | — | — |
| Seedream 5.0 Lite | — | — | 9 | 9 | 9 |
1.5K costs the same as 1K — they sit in the same price bracket. A larger image for the same price, so Pro defaults to 1.5K.
Lite is 9 credits an image at any resolution, and references never add to it Rates for every other model are on the pricing page

Layer decomposition
One image comes back split into stacked pieces — background, subject, text and so on — up to 17 at a time. In the layer studio you can stack them, reorder them, toggle what shows and save a flattened version.
Each piece costs half the normal rate: 6 credits at 1K and 1.5K, 12 at 2K. Only the pieces actually returned are charged.
Precision editing
You mark a coordinate on the image and the edit applies there, which is a good deal clearer than describing the spot in words. Exclusive to Seedream 5.0 Pro — Lite and the other image models do not have it.
Which one to pick
- You need 4K — Lite; Pro stops at 2K
- You need volume — Lite, at a flat 9 credits regardless of resolution or reference count
- You want to fix one spot — Pro, the only one with coordinate-based editing
- You will move parts later — Pro layer output, so background and subject arrive already separated
How billing works
Images are billed per image and only for what is actually returned. There is no monthly subscription, and credits stay valid for one year from the date of purchase. Failed generations are refunded.
