Higgsfield Soul at 720p or 1080p on Sume: 0.5 vs 0.75 cents a frame

Higgsfield Soul on Sume bills $0.005 per image at 720p and $0.0075 at 1080p, so 100 frames cost $0.50 or $0.75, always in calls of one or four images. The 1080p tier adds half a cent per hundred frames over 720p, so there is little reason to draft at 1080p unless the output goes straight into use. The catalog row is text-to-image only, with no reference images and no quality field.

These numbers are from the catalog and price tables on origin/main, read 2026-10-08. The catalog marks Soul's list price as the authenticated Higgsfield estimate for the Sume account, not a published tariff, so read the live endpoint line before you plan a very large run.

The row

The resolution values are 720p and 1080p, not the 512/1K/2K/4K tiers other rows use. The aspect list has seven entries: 1:1, 16:9, 9:16, 4:3, 3:4, 3:2 and 2:3. The output format is provider-selected PNG, and the catalog lists no output_format values, so omit that field.

Batch sizes

The provider code accepts only a batch of 1 or 4 for Soul. A request with n of 2 or 3 is not served as asked, so plan in fours. 25 calls of four give 100 frames, and a lone frame is one call of one. Each call is billed at the endpoint price times n; a failed generation is not billed.

Choosing the tier

Draft at 720p, where a hundred candidates cost fifty cents. Re-run the ten you keep at 1080p for another $0.075. Because Sume rejects seed, a rerun is a new sample, so mark the prompt, not the image, as the thing you are keeping.

If you need a reference photo to be respected, Soul is the wrong row; use an edit-capable one such as Seedream 5.0 Lite or Flux 2 Pro.

The row is a good fit for volume where each frame is cheap and the selection step is human. It is a poor fit when you need to hold a product or a face constant, because it takes no reference. If your frames need a particular ratio outside the seven listed, generate the nearest one and crop afterwards, or choose a row that lists the ratio you need.
