Generate images with Nano Banana from a prompt and optional references, in HD, 2K or 4K, then compare the results with your brief.

Article cards, backgrounds, mood studies and illustrations. Hover or focus an image to read the prompt behind it; open it to reuse the prompt in the creator above.
Editorial photograph for an article about a calmer morning routine: a hand holding a white cup of latte as milk is poured in, warm blurred cafe behind, one focal object, no text.
Small kitten sitting on a pale pillow, soft window light, simplified background, a clear silhouette that reads at small profile-image size.
Amber glass perfume bottle on a pale warm surface, soft afternoon shadow, quiet studio-like background in muted cream, empty space around the bottle, no text.
Simplified pencil illustration of a smiling woman in a wide-brimmed sun hat, soft shading, plain pale background, room on the right for a headline.
Reading corner with an armchair, a floor lamp with warm light and a small stack of books, limited palette of cream, amber and deep green, calm evening mood, no people, no text.
Close view of a child drawing a face with a pencil on white paper, loose construction lines, soft overhead light, neutral background, no readable text.
Bedroom with a low wooden bed, a framed landscape photograph above it and a few plants, muted earth tones, soft daylight from the left, no people, no text.
Photograph of a glass bakery display case filled with croissants and pastries on shelves, warm light, small price cards, shallow depth of field.
Each image was generated with Nano Banana from the prompt shown on its card.
Start with a visual brief for a new image, or a reference for a specific change. Decide the composition around where the image will appear.
Write a specific visual brief with three decisions: one focal subject, a treatment that survives a small display size, and room around the subject for the crop. Keep the verified headline in the page layout, not in the generated pixels. The image on the right was generated from this brief with Nano Banana.
Editorial photograph for an article about a quieter daily routine, a few handwritten pages on a pale desk, soft daylight, calm muted palette, one focal object with a quiet margin around it, no readable text.
Upload a supported image and say what should stay recognizable and what should change. A reference guides the subject or arrangement; it does not guarantee an exact copy, so compare edges, small lettering and shadows with the source before you use the result.
Three actions in the creator above.
Write the subject, style and composition in the prompt box, up to 4,000 characters. Add references only when each one answers a question, such as a subject or a palette. The creator accepts up to 14 in total.
Nano Banana is selected by default. Pick the aspect ratio for where the image will appear, then choose the supported output tier, HD, 2K or 4K, and one, two or four images. Start at HD while you compare compositions.
Review the actual image request before you confirm. The Generate button shows the estimate: 23 credits per HD image, 34 per 2K and 51 per 4K, multiplied by the number of images, so two 2K images cost 68. Check the result at its real display size, then download it or send it to an editing tool.
Four jobs where the Flash image model is the quick, lower-priced way to test an idea.
01
Nano Banana is the lower-priced model, so it suits drafts. Ask for several images per request, compare them against the same brief and keep the strongest direction before you move it to a higher tier or to Nano Banana Pro.
02
Article cards and cover art need space for a title. Describe the empty area in the prompt, such as a clear sky, a plain wall or a soft gradient, and keep the focal object to one side. Leave words out of the prompt and add the headline later.
03
Attach 14 reference images at most to guide a subject, a palette or an arrangement. Say what each reference is for. Nano Banana treats a reference as guidance and not as an exact copy, so check labels and proportions against the source.
04
Nano Banana costs 23 credits at HD, 34 at 2K and 51 at 4K per image. Test a direction at HD, then raise the tier for the version you will publish. The estimate appears on the Generate button before you confirm.
Both models accept text and reference images and offer the same three tiers. They differ in detail and price, so compare them on one brief before you choose.
| Nano Banana | Nano Banana Pro | |
|---|---|---|
| Best for | Fast, capable image generation and editing | 4K resolution and reasoning-guided quality, built for professionals |
| Resolution | HD · 2K · 4K | HD · 2K · 4K |
| Reference images | Up to 14 | Up to 14 |
| Credits per image | 23 HD · 34 2K · 51 4K | 45 HD · 45 2K · 80 4K |
Generate another image to test a different direction. Edit the one you have when the subject works and one part needs attention.
Nano Banana is the faster, lower-priced image model in Potto AI's generator, running on Google's Gemini 3.1 Flash Image. It supports HD, 2K and 4K, up to 14 reference images and the generator's ratio, count and format controls. Use the quote on the Generate button for the current price rather than older descriptions of the model.
No. In Potto AI, Nano Banana runs on Gemini 3.1 Flash Image, a newer model than the Gemini 2.5 Flash Image that first made the Nano Banana name popular. Not every setting described in Google's documentation is offered here, so rely on the controls and the quote shown in the creator.
No. Nano Banana supports HD, 2K and 4K at 23, 34 and 51 credits per image. The number of images multiplies the price, so two 2K images cost 68 credits. Start at HD while you compare compositions and move up only when the placement needs more pixels; older descriptions that limited the model to HD are out of date.
When the same brief leaves an important decision unresolved, such as whether lettering stays readable or fine detail holds at 4K. Keep the prompt, references, ratio and review criteria the same so the comparison answers that one question. Pro costs more and is stronger on detail and text, but neither model wins every task.
Up to 14 in total. Add a reference only when it has a specific job, such as supplying a subject, a composition or a visual direction, and say so in the prompt. Several images do not guarantee that every detail is preserved, so compare the important details with each source.
No. Verify every word and compare the important reference details in the actual result. Keep approved wording in editable layout text. A larger tier, multiple references, and a model name do not establish correct lettering, exact product fidelity, or an identity lock.
Name the one unresolved issue, such as space for text or the lighting direction, and write the next instruction around it while keeping the working parts of the brief. To change one area of a finished image, use the AI Image Editor; a prompt to change one object is not an exact mask, so check the rest of the picture. If edits pile up unwanted changes, return to a cleaner source.
You can write a prompt, add references and choose Nano Banana settings before signing in. Generate opens the sign-in dialog, and everything you entered stays in the creator.
The task explains why it stopped and offers a retry, and its credits are released. Stop a running Nano Banana request with the cancel control, since leaving the page does not stop it. Generating again after a finished image is a new request.
Nano Banana costs 23 credits per image at HD, 34 at 2K and 51 at 4K. More images multiply the price, and the Generate button shows the total before you confirm.
Describe the image, add references only where they have a job, and review the quote before you generate. Nano Banana is the quick, lower-priced way to test an idea.
