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 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. ## What to inspect with Grok Imagine Create images from a description and choose the version around whether you need to edit an uploaded photo. - 1.0: text with Speed or Pro priority, or editing one photo. - 2.0: new images from text; Segment Edit starts from an eligible generated result. Five aspect ratios are available for generation. - Segment Edit is not ordinary uploading of an arbitrary photograph into version 2.0. - Inspect lettering, logos and small objects separately. ## 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 [ 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/) [ Grok Imagine Create images from a description and choose the version around whether you need to edit an uploaded photo. ](https://mixerai.org/en/knowledge/image/grok-imagine/) ## FAQ Which is cheaper: Nano Banana 2.1 or Grok Imagine?
