How it works
Google publishes a per-image price by output resolution. OpenAI prices image output in tokens per million, so the per-image figure depends on the token count your generations produce; take it from the usage dashboard and enter it.
The formula
Google: per_image[size] * images; OpenAI: image_output_tokens * price_per_million / 1,000,000 * imagesWorked example
With the inputs the page opens on:
- images per month: 5000
- model: gemini-nano-banana-2.1
- size: 1K
- image output tokens: 0 tokens
gives
- cost per image: $0.0336
- monthly cost: $168
- cost per 1k images: $33.6
