AI image generation pricingNano Banana 2.1 workbench options
Generate and edit in one model
This page sends generation and editing requests to APIMart’s gemini-nano-banana-2.1 endpoint. Add reference images when an edit needs visual guidance, and inspect the result before using it.
1K, 2K and 4K settings
Choose a configured resolution and check the credit estimate before generating. Inspect detail and composition at the selected resolution; a higher setting does not guarantee a better result.
Wide and tall aspect ratios
The workbench offers aspect ratios including 1:4, 4:1, 1:8 and 8:1. Inspect wide and tall outputs for repeated patterns, cropped subjects and other artifacts.
Text and infographic prompts
Provide the exact words and their positions for text-heavy images. Check spelling, layout and readability in every result; accurate text is not guaranteed.
Up to 14 reference images for fictional characters and products
Use up to 14 references to guide a product or original fictional character. Scene and pose editing examples apply only to fictional characters; do not use them to fabricate scenes or actions involving real people. Details may drift across edits.
How to use Nano Banana 2.1
Describe your image or edit
Write a prompt that specifies the subject, composition, lighting and any exact text. For an edit, upload reference images and clearly separate what should change from the details you want to keep.
Set the resolution and aspect ratio
Choose 1K, 2K or 4K and an aspect ratio that fits your intended layout. This page starts at 2K; check the credit estimate before generating.
Generate, review and refine
Generate the image, then inspect the text, layout and reference details. For another edit, preserve the product, composition or original fictional character’s design. Do not apply fictional-character scene or pose changes to real people. Open the generator on this page

Nano Banana 2.1 prompts
Write a composition, not a tag list
Create a studio product photograph of four ceramic skincare bottles on a pale stone shelf.

Separate what changes from what stays
Edit the supplied original fictional character reference, which must not depict or identify a real person, into a rainy evening street scene.

Use natural reflections and soft street lighting. Aspect ratio 3:4, 2K.
Lock the words and their positions
Create a bilingual event poster on an ivory background. Place exactly "OPEN STUDIO" at the top center in large dark lettering. Place exactly "开放工作室" directly below it in a smaller size.
