Generate images with Nano Banana Pro from a prompt and up to 14 references, in HD, 2K or 4K, then check detail, lettering and how the references were used.

Posters, product concepts, illustrations and character studies. Hover or focus an image to read the prompt behind it; open it to reuse the prompt in the creator above.

Each image was generated with Nano Banana Pro from the prompt shown on its card.
Start with a brief for a new visual, or a reference for a specific change. Decide the composition around where the image will appear.
Give Nano Banana Pro three clear decisions: what to show, how it should look, and how the figure sits in the frame. If the poster carries a headline, keep it to a few words so you can check every letter. The image on the right was generated from this brief.
Pop-art poster portrait of a young man with curly orange hair in a mint hoodie, halftone shading, bold black outlines, flat teal, orange and cream geometric background, figure low in the frame, no text.
Upload a supported image and say what should stay recognizable and what should change. A reference guides the subject, shape or arrangement; it does not guarantee an exact copy, so compare labels, lettering and proportions 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 reference images only when each one has a job, such as a product shape or a palette. The creator accepts up to 14 in total.
Nano Banana Pro is selected by default. Pick the aspect ratio for where the image will appear, then HD, 2K or 4K and the output format. Choose 4K only when the placement needs it; a larger tier does not fix an unclear brief.
The Generate button shows the estimate: 45 credits per HD or 2K image and 80 per 4K image. Results appear under the creator. Check lettering and reference details at full size, then download the one that works or send it to an editing tool.
Four jobs where the Pro image model earns its place: lettering, references, output size and revisions.
01
Choose Nano Banana Pro when the image carries words, such as a poster headline, a product label or a menu board. Put the exact words in quotes inside the prompt and keep them short, then read every letter at full size before you use the result.
02
Add a subject, a palette or a room layout as a reference and say what must stay recognizable. A reference guides the result without guaranteeing an exact copy, so compare shape, labels and proportions with the source.
03
A Nano Banana Pro image costs 45 credits at HD, 45 at 2K and 80 at 4K. Pick the aspect ratio first, then the tier. Reserve 4K for large screens or print: extra pixels never make up for a vague brief.
04
When a result is close, change a single instruction and generate again, or send the image to the editor for a local change. Every new request is priced on its own, so keep the parts that already work written into the prompt.
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 Pro | Nano Banana | |

| Best for | 4K resolution and reasoning-guided quality, built for professionals | Fast, capable image generation and editing |
| Resolution | HD · 2K · 4K | HD · 2K · 4K |

Generate another image for a new concept. Edit the one you have when the subject works and one part needs attention.
Nano Banana Pro is Google's Gemini 3 Pro Image model, available in Potto AI's image generator. It supports HD, 2K and 4K output, up to 14 reference images, and the generator's ratio, count and format controls. It is the stronger choice for fine detail, lettering and 4K, but no model name guarantees the right result for every image.
Pro is the larger model and costs more: 45 credits per image at HD or 2K and 80 at 4K, against 23, 34 and 51 for Nano Banana. Pro is the one to try first for lettering, dense layouts and 4K; Nano Banana suits fast drafts and variations. Run the same brief and references through both and judge them by the same criteria, because neither 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. Use editable layout text when accuracy is essential. A larger tier, multiple references, and a model name do not establish correct lettering, exact product fidelity, or an identity lock.
No. Treat the creator as a prompt-and-references tool: it does not browse the web or verify the facts in your prompt. Features described in Google's developer documentation are not automatically available here. Check names, figures and dates yourself before you publish an image that shows them.
Use 4K when the placement needs more pixels, such as a large display or a detailed layout; it costs 80 credits per image against 45 at HD or 2K. A larger tier does not fix an unclear composition or a misspelled word, and the exact pixel size depends on the model and the ratio, so check the downloaded file. For print, judge the file against your print workflow; the image is raster output, not a print-ready or editable-type file.
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 Pro settings before signing in. Generate opens the sign-in dialog, and your prompt, references and settings are kept.
The task shows the reason and offers a retry, and the reserved credits are released. Cancel a running Nano Banana Pro request from its task controls; closing the preview does not stop it. A new attempt on a finished image is charged again.
Nano Banana Pro costs 45 credits per image at HD or 2K and 80 credits at 4K. Two or four images multiply the price. 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. Credits are spent only when you press Generate.
