Budget for 100 image ads on Sume: seven models, one image per job

One hundred image ads, each its own single-image job, cost $3.00 on Grok image, Qwen Image or Imagen 4 Fast, $10.00 on Qwen Image Max and $10.00 on Nano Banana 2.1 at 1K. The reason it is not $2.50 for the cheap rows is the per-job round-up to the next cent: $0.025 becomes $0.03.

Table: 100 jobs, one image each

Per-image figures are provider list x 1.25 from the repo price table. The job column rounds each job up to a cent, which is how a single-image job is billed (image docs).

When batching beats one-by-one

The images API takes n up to 10 per call, with lower ceilings on some models (read the n range from the catalog). If a row allows n=10, ten jobs of ten images cost $2.50 at $0.025 per image, against $3.00 for 100 single-image jobs, because the round-up applies once per job.

Add reference-image costs and retakes on top; this table is the clean-run floor for 100 stills.
