Nano Banana 2 vs GPT Image 2
Nano Banana 2 and GPT Image 2 compared on price, resolution, reference images and in-image text — 1,000 credits versus 15,000, and when the difference is worth it.
Short answer
Use Nano Banana 2 by default and GPT Image 2 when the image contains text or the brief is a long compound instruction. The practical workflow is to draft on Nano Banana 2 Lite at 500 credits, settle the composition, then re-render the chosen one on GPT Image 2 if it needs legible words. Reaching for GPT Image 2 first is how you spend 15,000 credits learning that the composition was wrong.
A fifteen-fold price difference deserves a clear reason, and there is one: GPT Image 2 can spell. If your image contains words — a poster, packaging, a UI mockup, a sign in the background — it is the only model in the catalogue that reliably gets them right.
For everything else, Nano Banana 2 at 1,000 credits lets you generate fifteen variations for the price of one GPT Image 2 render, and picking the best of fifteen usually beats one careful attempt.

A green cell is the better value in that row. Every price is what DubVoice.ai charges — one credit balance covers all of these models.
Which one should you use?
General image work, product shots with references, or anything you want to iterate on.
The image contains text, or the prompt is a long list of spatial instructions that must all be honoured.
Frequently asked questions
Which AI image model is best for text in images?
GPT Image 2. It is the only model in the DubVoice.ai catalogue that reliably renders legible, correctly spelled words, which makes it the right choice for posters, packaging and mockups.
Is GPT Image 2 worth 15x the price of Nano Banana 2?
Only for text and for long compound instructions. For general image generation, fifteen Nano Banana 2 attempts will produce a better final image than one GPT Image 2 render, because you get to choose.
Which one can output 4K?
Neither directly. GPT Image 2 caps at about 1.57 MP. Nano Banana Pro — the 3,500-credit tier of the Nano Banana family — is the only model here with a 4K upscale.
