# Credit costs

> How a price is arrived at, and roughly what things cost.

Source: https://advibly.com/docs/reference/credit-costs



## The formula [#the-formula]

One credit is one US dollar. A generation's price is the underlying compute
cost with a fixed markup applied, rounded up - to the nearest 0.01 credit for
images and 0.1 for video.

Nothing else affects it: there is no per-seat charge, no minimum, and no
difference between a credit granted by a subscription and one bought in a pack.

For planning, count **billable calls**, not final deliverables. A five-shot ad
can include five stills, five clips, voiceover, music, and one composition even
though the user receives one video.

## Rough figures [#rough-figures]

Everyday defaults, to calibrate expectations:

| Generation                             | Approx. cost                       |
| -------------------------------------- | ---------------------------------- |
| One image, cheap model, 1K             | \~0.09 credits                     |
| One image, GPT Image family, medium    | a few hundredths to \~0.05 credits |
| One image, high quality                | several times the medium price     |
| 8-second video, 720p, everyday model   | \~1.9 credits                      |
| 8-second video, 1080p or premium model | several times that                 |
| Talking actor, 15 seconds, 720p        | \~2 credits                        |
| Voiceover, 30 seconds                  | a fraction of a credit             |
| Composition render                     | 0.4 credits                        |

## What drives the price [#what-drives-the-price]

<Accordions>
  <Accordion title="Video: duration and resolution">
    The two dominant factors, and they multiply. Halving the duration halves the
    price; dropping 1080p to 720p typically does more than that.
  </Accordion>

  <Accordion title="Images: size and quality tier">
    Quality tiers are not linear. On supported GPT Image models the highest tiers
    are several times the medium price for the same dimensions.
  </Accordion>

  <Accordion title="Reference images">
    Most image models add a small per-reference charge. Three references on a
    cheap model can cost more than the base image.
  </Accordion>

  <Accordion title="Subtitles">
    A base per-minute rate, doubled for dynamic caption styles, doubled again
    above 1080p, with a further per-minute charge if translated.
  </Accordion>
</Accordions>

## The authoritative number [#the-authoritative-number]

The MCP tool schema and the client's approval prompt describe the billable
operation before it runs. Use `advibly_check_credits` before a multi-call
workflow, and `advibly_buy_credits` to retrieve current packs and checkout
links. This page is for rough planning; model IDs and prices can change.

Before a multi-call workflow:

1. Resolve the exact number of image, video, audio, and render calls.
2. Read the live schema for each selected model and setting.
3. Call `advibly_check_credits`.
4. Tell the user which planned steps spend credits before starting the batch.

The estimate is ready only when it covers every proof, variant, retry budget,
and final render—not just the finished deliverable.
