Credit conversion: a model list by accident
A credit conversion table says how far a credit goes on each model. It exists to explain what a plan buys, and the only honest way to do that is to name the models, so it publishes a model list as a side effect of arithmetic. That makes it unusually complete and unusually fragile. As of 2026-09-22.
| Published as a side effect | Mixed together on the same table |
|---|---|
| Every purchasable model, by name | A price change and a retirement |
| Which models the seller expects to be costly | House lines and licensed lines |
| Variants, where they are priced separately | Video models and image models |
| A unit the seller defines | Nothing marking which is which |
Inclusion rule. Read from the credit conversion table of the one entry in this register that prices in credits. Order. What the table reveals first, then what it conflates.
1A by-product is fragile disclosure
Nothing commits a page to keeping its arithmetic explicit. A plan described in flat credits would remove every model name without retiring anything, and the disclosure would disappear with no announcement.
It is unlikely for a practical reason rather than a principled one: remove the names and a credit becomes an unexplainable unit.
2Two changes look identical on the page
A conversion rate can move while the model stays, and a model can leave while the rates around it stay. The first is a price change and the second is a retirement, presented in the same typeface with nothing announced.
So a production watching this page has to record both numbers. Either one moving invalidates a plan built on the other.
3The abstraction sits between the customer and the model
Because the unit sold is a credit, the seller can change what it buys without changing anything a customer bought. Pricing seconds directly removes that ambiguity at the cost of a less flexible product.
The two units read against each other set out what each arrangement makes visible when something moves.
A definition rather than a dated entry: no line above is a vendor statement. Where this word turns up in a real notice, the wording and the date are on the reading on that table. Nearby terms: Output unit, Tier gating, Default engine.
4Production that outlasts a model
Model end dates touch “Credit conversion”; SceneMixer's guides describe how its pipeline treats the models it runs:
SceneMixer writes dialogue into the script analysis, assigns each line to a shot with a speaker and a short delivery note, and the video model performs it — picture and audio generated together, so the mouth forms that sentence in the language you chose.
