Cost per approved asset is the model metric that matters
Measure credits and edit time per approved image, clip, or caption rather than trusting a model’s sticker price alone.
The short answer
A per-token or per-second price is a useful input, but it is not the cost of a usable release asset. Measure the total credits and edit time spent to reach approval. This makes a cheap model with frequent rejections comparable to a dearer model that produces more usable work.
The denominator is approval
For a video batch, record the number of generated clips, total credits, clips approved, and minutes of human repair. Then calculate credits per approved clip = total credits ÷ approved clips. If ten clips cost 100 credits and two are approved, the effective rate is 50 credits per approved clip. If four clips cost 80 credits and three pass, it is about 27 credits. The lower sticker price can lose after rejection.
Apply the same logic to copy and images, but do not collapse all media into one score. A caption may be cheap and easy to revise; an identity-defining image may deserve a stricter approval threshold. Record the specific reason for rejection: factual error, inconsistent character, poor crop, unusable motion, or simply wrong artistic direction.
What Studio can already show
Studio’s Billing area includes usage by model and a credit history. Some generators may not yet report their model in the usage breakdown; the interface explicitly flags this coverage gap. So a model-level report is useful but not a complete evaluation dataset. Add a small production log for the approved asset count and edit time.
Change one decision at a time
The data should change one decision at a time. If a model produces consistent artwork but weak motion, keep it for images and switch the shot workflow. If a costly text model saves no edit time on routine captions, use a lighter default and reserve it for difficult story work.

Questions, answered.
- How is cost per approved asset calculated?
- Divide total credits spent on a batch by the number of outputs actually approved.
- Is Studio’s usage by model complete?
- The Billing view flags that some generators do not report their model, so use a small production log as well.
