How the arithmetic works
34 of the 34 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 = the model's per-second rate x the number of seconds you generate. Nothing else moves it — resolution, prompt length and aspect ratio are all free.

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 34 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.

How these models are billed
Every model on this page uses the same billing shape.
- Charged per second of output34 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 second?+
34 on Versely — 21 video, 11 lipsync & avatars, 1 audio & voice and 1 video upscaling, from 16 providers. credits = the model's per-second rate x the number of seconds you generate. Nothing else moves it — resolution, prompt length and aspect ratio are all free.
Is a per second model cheaper?+
Not in itself — the shape is how you are charged, not how much. Across these 34 models a complete job runs 2 to 200 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 second?+
PrunaAI P-Video has the lowest complete-job cost of the 34 at 2-32 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 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.
