AI credit cost calculator
Work out what a job costs before you run it. 303 models, 14 billing shapes, each with its own arithmetic — and the working shown, so the number is checkable rather than magic.

The billing shapes in the catalog
These are not variations on one formula. Each one meters something different, which is why comparing two models on their headline figure alone is usually a mistake.

FAQ
- Why do two models with the same headline number cost different amounts?
- Because the number means different things. The catalog bills on several structurally different shapes — per second of output, per image returned, per megapixel, per 1,000 characters, per 5-second block, and flat per generation. A model billed per second and a model billed flat are not comparable on their headline figure at all. The calculator picks the right arithmetic for whichever model you select and shows the working.
- Why does the calculator sometimes refuse to show a figure?
- Because the model's own published data contradicts itself. Multiplying a per-second rate by a supported duration can produce a number above the credit ceiling that same model declares for a job. One of the two figures is wrong and the catalog does not say which, so nothing is shown rather than picking a side. The model page is authoritative in those cases.
- Is there a free tier?
- No. Every generation costs credits, and the cheapest model in the catalog still costs credits, so there is no zero-credit option. The one thing that is free is the editor's 480p preview pass, which carries a short per-user cooldown; a single charge applies to the final export only.
- What is a 5-second block?
- Some models meter whole 5-second blocks rather than individual seconds. A 6-second clip occupies two blocks and costs exactly what a 10-second clip costs, so on those models it is worth filling the block you are already paying for.
