What is Nano Banana 2?
Nano Banana 2 is Google's image model, exposed on monalisa-1 through Kie for both text-led generation and reference-image editing. A single catalog entry serves both workflows, so moving from creating to editing does not change the model, the controls or the price.
It is the composite specialist in the monalisa-1 catalog. The uploader takes up to 14 reference images in one request, which is what makes it the right pick when a scene has to be assembled from several sources rather than described from scratch. Each run costs a fixed 15 credits.
One model ID, two workflows
Text to image and image to image resolve to the same upstream entry, with the same seven aspect ratios, the same 1K, 2K and 4K resolutions and the same PNG or JPG output switch. There is no separate editing model to learn or to select.
Reference count and accepted option values are enforced by the monalisa-1 server-side catalog rather than by the browser. If an option is not on the list, the request never reaches the provider and no credits are spent. Note that monalisa-1 here means the site you are generating on — the monalisa-1 model of the same name is still in development and cannot be selected.

How to generate with Nano Banana 2 on monalisa-1
Creation and editing share one model ID on monalisa-1, so the workflow is the same whichever direction you start from.
- 1
Choose creation or editing
Both run on the same model ID. Text to image starts from the prompt alone; image to image opens the uploader for up to 14 references.
- 2
Stack your references
Add every source you want represented — a subject, a location, a palette board, a product shot — and say in the prompt what each one contributes. This is where the 14-image allowance earns its 15 credits.
- 3
Set ratio, resolution and format
Pick one of the seven ratios, choose 1K, 2K or 4K, then select PNG for flat and graphic work or JPG for photographic output and smaller files.
Nano Banana 2 vs the other models on monalisa-1
Every model on monalisa-1 is priced and limited differently. These are the trade-offs that decide whether Nano Banana 2 is the right entry for the job in front of you.
Nano Banana 2 vs Nano Banana Pro
Same family name, different upstream models. Nano Banana 2 is 15 credits and takes up to 14 references; Pro is 45 credits and caps references at 8. The higher price is not a published quality ranking, so run both on the same prompt before you commit a project to Pro.
Nano Banana ProNano Banana 2 vs GPT Image 2
GPT Image 2 is 6 credits, takes up to 16 references and offers an auto aspect ratio, but splits generation and editing across two upstream entries and enforces ratio-to-resolution rules. Nano Banana 2 costs more and keeps everything behind one model ID, with a PNG or JPG switch GPT Image 2 does not expose.
GPT Image 2Nano Banana 2 vs Z-Image
Z-Image is 4 credits and text to image only, with no uploader and a 1,000-character prompt limit. Sketch there, then bring the direction into Nano Banana 2 when the image needs references, 4K or a format choice.
Z-ImageWhere Nano Banana 2 fits on monalisa-1
- 1
Multi-source composites
Scenes assembled from several references at once — subject, setting, palette and product in a single request.
- 2
Mood boards and direction
Fast exploration of a look before a campaign is locked, with the same model still there for the follow-up edits.
- 3
Iteration-heavy visuals
Social, editorial and product images that get reworked repeatedly without switching models mid-project.
Nano Banana 2 FAQ
Can Nano Banana 2 edit existing images?
Yes. The same catalog entry covers text to image and image to image, so editing needs no model switch — upload the references and describe the change.
Which output formats does Nano Banana 2 support?
PNG and JPG. Choose PNG for flat, graphic and line-heavy work, and JPG for photographic output and smaller files.
Is Nano Banana 2 the same as Nano Banana Pro?
No. They are separate upstream models with different prices (15 against 45 credits) and different reference limits (14 against 8). Select them independently in the generator.
How many reference images can I upload?
Up to 14 in a single image-to-image request — the highest allowance in this catalog after GPT Image 2's 16.
How many credits does one Nano Banana 2 generation cost?
A fixed 15 monalisa-1 credits, resolved server-side and unchanged by resolution, format or reference count.
Which aspect ratios are available?
Seven: 1:1, 4:3, 3:4, 16:9, 9:16, 2:3 and 3:2. There is no auto option, so the frame is always a deliberate choice.
Can Nano Banana 2 output 4K?
Yes. 1K, 2K and 4K are all selectable, and the credit cost is the same at each of them.
How long can a Nano Banana 2 prompt be?
Up to 5,000 characters, which is room enough to describe what each of the 14 references should contribute to the final frame.
