Getting Started with Nano Banana 2.1
Three quick moves carry you from a rough idea to a polished picture.
What Nano Banana 2.1 Can Do
Ultra-sharp 4K rendering, clean on-image lettering, fourteen reference slots and chat-based tweaks that never damage your original.
Crisp 4K Resolution
OpenArt gives every model several resolution and ratio choices, and Nano Banana 2.1 pushes all the way to 4K output.
Legible Lettering In-Frame
Type that stays sharp and correctly shaped means packaging copy, restaurant menus and signage all come out easy to read.
Up to 40 Shots From One Upload
A single product photo is all it takes to fill a whole session with new shots in the lighting and colors you pick.
14 Reference Slots Per Prompt
You can load as many as fourteen reference images into one prompt, and the model blends them with your text for a first-pass result you can actually use.
Chat Edits That Preserve the Original
Ask in chat for a different shirt shade, a fresh outfit or smoother skin, and get a polished result without any hands-on retouching.
Style Swaps That Keep Every Detail
Convert your own upload into anime, cyberpunk, claymation, pencil sketch or oil paint, cleanly enough that the edit never shows.
Questions About Nano Banana 2.1
Answers to the questions people ask most about references, chat editing and 4K output.
How many reference images fit in a single prompt?
Up to fourteen. The model reads each one closely and blends them together with whatever you type.
What can one reference photo produce?
As many as forty distinct images can come from a single reference, and the look stays consistent across the whole set.
Will a chat edit change the rest of the image?
No. Only the region you describe gets touched — everything around it is left as-is rather than being regenerated.
Can it put readable text inside an image?
Yes. Letterforms are drawn accurately and in detail, so labels, menus and street signage stay legible in the final picture.
Could I build a product catalog from a handful of shots?
Photograph your product from a few angles, upload them, and the model picks up its look and feel to deliver catalog-ready images with clean label text.
Which art styles work on my own photo?
Your upload can become anime, cyberpunk, claymation, pencil sketch, oil painting or countless other looks, with objects and outfits swapped while the fine detail survives.
