API image models bill per picture. Subscriptions hide the same math behind a monthly fee. This calculator turns both into a batch total so you can decide before you hit generate.
Prices last checked August 2026. Flux Schnell is the cheap iteration lane. Flux Pro and GPT Image cost more because they render cleaner text and faces. Midjourney has no public API — the number you see is the Standard plan divided by a typical fast-image allotment. Confirm on the provider page before you commit a large run.
Flux Schnell is about $0.003 per 1024 image on Fal or Together. Flux Pro 1.1 is about $0.04. Volume is where Schnell wins.
The xAI image API is about $0.03 per standard image. SuperGrok includes a monthly quota if you already pay for the chat plan.
If you actually use the fast images on a $30 Standard plan, effective cost lands around $0.03 each. If you only make a few dozen a month, pay-as-you-go on Flux or GPT Image mini is cheaper.
