How the arithmetic works
8 of the 8 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 charge covering the first 5 seconds, plus a per-second rate for everything after that. Short clips are dominated by the base, long ones by the rate.
| Model | First 5 seconds | Each extra second | A 10-second clip |
|---|---|---|---|
| Kling 2.5 Turbo | 9 credits | 2 credits/second | — |
| Kling V2.1 | 14 credits | 3 credits/second | — |
| Kling Video V3 Standard Image to Video | 26 credits | 6 credits/second | 56 credits |
| Kling Video V3 Pro Text to Video | 34 credits | 7 credits/second | 69 credits |
| Kling O1 Image to Video | 45 credits | 9 credits/second | 90 credits |
| Kling O3 Standard Image to Video | 45 credits | 9 credits/second | 90 credits |
| Kling O3 Standard Reference to Video | 45 credits | 9 credits/second | 90 credits |
| Kling O3 Pro Image to Video | 56 credits | 12 credits/second | 116 credits |
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 8 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.

Frequently asked questions
Which AI models are billed base charge plus per second?+
8 on Versely — all of them video models, from 1 providers. credits = a fixed charge covering the first 5 seconds, plus a per-second rate for everything after that. Short clips are dominated by the base, long ones by the rate.
Is a base charge plus per second model cheaper?+
Not in itself — the shape is how you are charged, not how much. Across these 8 models a complete job runs 9 to 56 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 base charge plus per second?+
Kling 2.5 Turbo has the lowest complete-job cost of the 8 at 9-17 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 base charge plus per second 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.
