Image upscale cost on Sume: the price per image
Image Upscale 1.0 on Sume reserves a fixed amount per image, so upscaling a batch costs up to that amount times the image count.
Image Upscale 1.0 on Sume reserves a fixed amount per image, sized for a large generative upscale, so upscaling a batch of images costs at most that amount times the number of images. The table gives the ceiling for every batch these posts priced.
Worked example: Upscale 400 images with an API: $80.00 on Sume
Upscaling 400 images costs up to $80.00 on Sume: Image Upscale 1.0 reserves $0.20 per image, which is a reserved ~16-megapixel Topaz generative (Wonder 3.5) job at $0.08 per started 8 MP, plus margin.
That is the rate-card basis as of 2026-10-06; smaller outputs can settle for less than the reserve.
What does the reserve look like by batch?
Reserved amounts, not final settlement:
| Images | Reserve |
|---|---|
| 400 | $80.00 |
| 800 | $160.00 |
What should I plan for?
Read the live price in GET /v1/catalog (sume/image-upscale-1.0).
- Upscale only the keepers: generate at a smaller size first.
- Keep the wallet above the total reserve or the job returns 402

Idempotency-Keyper image.
