Where image API costs go off the rails
Agents retry harder than humans

Per-image math hides in plain sight
A few cents looks harmless until CI, previews, and marketing drafts all call Seedream 3.

Most UI chrome is filler. Stock from a flat plan beats another Seedream 3 synthesis.
Scenario: Content placeholders with Seedream 3
A marketing site, docs portal, or newsletter uses Seedream 3 (ByteDance) to fill hero and card slots while copy is still fluid. Each editorial pass regenerates images “just in case,” often around tags like city, architecture, night. Stakeholders review layout, not generative novelty—so unique synthesis is wasted. Swap non-final slots to Epochal catalog images: real, licensed, searchable, and flat-priced. When the headline freezes and the brand needs a one-of-a-kind frame, run Seedream 3 once, cache the winner, and stop the churn.
The fix: Epochal Stock at $50 USD/month (no per-image fee)

There is no per-image fee and no free tier in v1.
