AI models billed per 1,000 characters

12 on Versely — all of them audio & voice models, from 8 providers. credits = a per-1,000-character rate x the length of the text you send. This is the one shape where the bill is set entirely by your input and not at all by the output.

Not in itself — the shape is how you are charged, not how much. Across these 12 models a complete job runs 0 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.

Chatterbox TTS has the lowest complete-job cost of the 12 at 2 credits (headline rate). The worked example table above shows the same arithmetic applied to every model that publishes enough of its matrix to support it.

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. 12 of the models here publish no complete-job cost at all, only a rate, so for those there is no like-for-like figure to compare. Versely's ranked buyer guides sort on complete-job cost for exactly this reason.
