Nano Banana 2 vs GPT Image 2.5

Both models cost within a few credits of each other, both accept reference images and both work in the editor. The difference is mostly in taste: how each interprets a short prompt when it has room to decide.

Every image was generated on Pixmint with the prompt printed above it. Each prompt was run once per model, so these are single samples and impressions, not a benchmark.

Speed class describes where each model sits in its family (Flash-class models are positioned for speed, Pro-class for quality). It is not a measured timing: actual generation time varies with the model, the image size and the load.

The images above were generated on 2026-10-22, one run per model per prompt. This is a set of single samples to look at, not a benchmark. Here is exactly how they were made.

Pick Nano Banana 2 (18 credits) if:

• You want photographic, documentary-feeling scenes with background life.
• You work with photos of documents or text-heavy images (the shadow remover's document scene runs on Nano Banana 2).
• You like mockup-style results, such as a poster shown as a physical object.

Pick GPT Image 2.5 (15 credits) if:

• You want finished, designed compositions: posters, covers and promos.
• You want large, clearly framed subjects, such as product shots.
• You mostly edit photos: GPT Image 2.5 is Pixmint's default editing model.
• You want the lower price: 15 vs 18 credits.

If you cannot decide, generate your prompt with both. It costs 33 credits to see both once, and the difference between a documentary and a designed look is usually obvious at a glance.

A reliable method takes two minutes:

• Open the tool at the top of this page, write your prompt and generate one image with Nano Banana 2.
• Switch the model to GPT Image 2.5 in the model list and press Generate again with the same prompt and aspect ratio.
• Compare composition first, then fine detail, then text if any. Pick one and keep iterating on that model.
• If you are signed in, both runs together cost 33 credits. The signup bonus (50 credits) plus the first day's daily credits (20) covers 2 such comparisons.

Nano Banana 2 costs 18 credits per image and GPT Image 2.5 costs 15. A failed image is refunded automatically, so you pay only for the images you receive.

One credit is worth about $0.01 at the planned list price. The signup bonus of 50 credits and the 20 daily credits are enough to try several of the paid models, and the photo tools cost 15 credits per run.
