Inspect more than overall style: object preservation, geometry, faces and hands, fine detail, text in the frame and unintended changes during editing. ## What to inspect with GPT Image 2 Create an image from a brief or edit an existing one with plain-language instructions. - Text or uploaded photos; choose 1, 2 or 4 results. - 1K, 2K and 4K. Auto and transparent background require 1K; a 1:1 square is unavailable at 4K. - Editing does not guarantee pixel-identical preservation of untouched areas. - Compare faces, branding and fine lettering against the source at full size. ## What to inspect with Nano Banana 2.1 The new Nano Banana: up to 10 references, 15 aspect ratios and quality up to 4K. - From text or from photos: 1 to 10 JPG, PNG or WebP images, up to 30 MB each. - 1K, 2K or 4K; 15 aspect ratios, including Auto and very narrow or wide ones. - Ten references is a ceiling, not a recommendation for every task. - More pixels do not fix mixed-up characters or a wrong product shape. ## How to run a fair comparison - Give both models one prompt, one aspect ratio and, for editing tests, the same source photo. - Look at the small things: hands, small text, product edges and logos fail differently in every model. - Generate at least three variants per model: one picture shows one seed, not the usual quality. - Compare cost at the resolution you will actually publish, not at each model's cheapest setting. ## Sources Prices, availability and specifications come from the Mixer AI catalog. This is not an independent test: try both models on the same task before choosing. - [Prices and availability — Mixer AI catalog](https://mixerai.org/knowledge/catalog.json) ## What we compare [ GPT Image 2 Create an image from a brief or edit an existing one with plain-language instructions. ](https://mixerai.org/en/knowledge/image/gpt-image-2/) [ Nano Banana 2.1 The new Nano Banana: up to 10 references, 15 aspect ratios and quality up to 4K. ](https://mixerai.org/en/knowledge/image/nano-banana-2-1/) ## FAQ Which is cheaper: GPT Image 2 or Nano Banana 2.1?
