How the arithmetic works
3 of the 3 carry enough in their price matrix to work the shape through end to end, and the table below does exactly that with each model's own figures. No two billing shapes on this site share a model — a model has exactly one — so nothing here overlaps another billing page.
credits = a fixed figure for every image the job hands back, so asking for four costs four times asking for one. Batch size is the only thing that moves it — prompt, resolution and aspect ratio are all free.
| Model | Per image | A batch of 4 | Headline vs full price |
|---|---|---|---|
| Seedream Edit | 2 credits | 8 credits | 3 full, 2 now |
| Kling Image O1 | 3 credits | 12 credits | no discount |
| Wan 2.7 Pro Edit | 8 credits | 32 credits | no discount |
Worked from each model's own price matrix. A cell reading “—” is one where the arithmetic produces a figure outside the complete-job range the same matrix declares, so nothing is printed.
All 3 models
Cheapest complete job first. Every row links to that model's spec page — tier and mode variants share a page with the model they are a variant of, so this is products rather than SKUs.
| Model | Provider | Credits per job | Its priced options |
|---|---|---|---|
| Seedream Edit | ByteDance | 2 credits | Price 2 |
| Kling Image O1 | Kling | 3 credits | Price 3 |
| Wan 2.7 Pro Edit | Wan | 8 credits | Price 8 |
How these models are billed
Every model on this page uses the same billing shape.
- Charged per image3 models
All figures are Versely credits. A credit figure marked as a headline rate is not the cost of a complete job. Your plan's credit allowance is on the pricing page.

Frequently asked questions
Which AI models are billed per image returned?+
3 on Versely — all of them image models, from 3 providers. credits = a fixed figure for every image the job hands back, so asking for four costs four times asking for one. Batch size is the only thing that moves it — prompt, resolution and aspect ratio are all free.
Is a per image returned model cheaper?+
Not in itself — the shape is how you are charged, not how much. Across these 3 models a complete job runs 2 to 8 credits. What the shape does tell you is which lever moves your bill, and on this page that lever is the same for every model listed.
What is the cheapest model billed per image returned?+
Seedream Edit has the lowest complete-job cost of the 3 at 2 credits. The worked example table above shows the same arithmetic applied to every model that publishes enough of its matrix to support it.
Can I compare a per image returned model against one billed another way?+
Only on the cost of a complete job, never on the headline figure. That is the whole reason these pages are split by shape — a rate compared against a job total is two different quantities in one column. Versely's ranked buyer guides sort on complete-job cost for exactly this reason.
