Image API cost
Image generation bills per output, not per token — but the per-image price swings 50× between a 512px draft and a high-res edited output. The real cost driver is your regeneration rate: typical pipelines discard 1–3 images for every keeper, and each discarded attempt is billed.
The formula
attempts = keepers × (1 + regen%)
images = attempts + keepers × edits% (edits priced at 1.5×)
total = images × price + storage
Per-image price is an editable input because vendors quote by size/quality tier and change often — check your provider's current page and paste it. As of . Excluded: moderation retries and video models (different price class entirely).
