Choose an image API by the asset your application must produce and the edits it must support. Compare matching output conditions and inspect the actual generated files before judging cost.
What matters for image generation apis
Write a fixture that specifies composition, subject, required text and delivery format. If the application needs editing, include a reference image and a precise change while identifying what must remain consistent. A text-to-image demonstration does not establish that a model supports the required edit workflow.
Distinguish image input from image output. A model that describes a picture is not automatically a generation endpoint. Filter for documented output capability, then inspect the model’s allowed size, quality and response representation in the official guide.
Google uses Nano Banana for Gemini’s native image-generation family, with distinct model identifiers and feature positioning. Official documentation.
The Nano Banana API keyword refers to programmatic image capabilities here. Select an actual documented model route rather than sending a family nickname as an identifier. Use the same visual fixture across candidates and inspect spelling, geometry and consistency at the output’s intended display size.
Ranked candidates
Only active candidates with documented values for this ranking are included. Prices retain the tier and deployment condition shown below.
This ranking uses documented image-output fees. Image-input fees and token-priced image generation are excluded because they use different billing measures.
No verified records are available for this selection.

A per-image ranking is comparable only when the output conditions match. Some services use token or other accounting for image work. Keep those categories distinct and do not imply that a missing per-image row means the model generates images for free.

The cheapest role is appropriate when it meets the required visual fixture at the chosen conditions. Balanced can be useful when editing fidelity and ordinary generation both matter. A strongest role needs comparable visual evaluation; neither price nor context can establish it.
Evaluate an accepted asset rather than an attractive thumbnail alone. Check the final file, intended crop, required text and whether the requested edit preserved unrelated content. Include the number of regeneration attempts needed to reach acceptance.
When each pick is wrong
A low-rate model is wrong when repeated attempts are necessary to correct text or composition. A powerful editing model is unnecessary when the application only needs a simple asset that a cheaper candidate reliably produces. Keep the task boundary explicit.
An image-understanding candidate is wrong for a generation task even if it appears under a broad image modality filter. Verify output capability and the actual endpoint. A route can also be wrong if its delivery representation does not fit the application’s file-processing workflow.

Use the calculator only for categories it supports, and keep per-image or other media-unit costs visible in the model’s live price table.
Budget accepted assets, including necessary regeneration and editing stages. Do not convert media units into guessed text tokens. Preserve output settings with the estimate so a later quality or size change can be priced correctly.
