Nano Banana 2.1, 2 and Pro are three parallel options on this site, not an upgrade ladder. 2.1 is the newest and the one we default to: it holds up at 4K, takes up to 14 reference images, and fixes the tiling artifacts that used to appear in extreme wide and panoramic ratios. Reach for Pro when layout precision and fine typography matter more than speed; reach for 2 when you are still exploring a direction. Run the same prompt through all three and compare before you commit to one.
AI image generation pricingWhat's new in Nano Banana 2.1
Generate and edit in one model
One model handles both image generation and editing, so you can make changes over several rounds without switching tools. Google’s official guidance is “Recommended for all new projects to use Nano Banana 2.1”.
Across-the-board quality at 1K, 2K and 4K
Realism and detail improve over Nano Banana 2 at all three output resolutions. Do not treat 4K as an enlargement setting: settle the composition at 1K before spending credits on a final render.
Tiling fixes for extreme aspect ratios
The model supports 15 aspect ratios, including the extreme banner and vertical formats 1:4, 4:1, 1:8 and 8:1. Nano Banana 2.1 specifically fixes the tiling artifacts that appeared in these ratios at 2K and 4K.
Sharper text and infographic layout
In-image text rendering and infographic layout accuracy improve in Nano Banana 2.1. Multilingual designs are more reliable, especially when you supply the exact words and their positions.
Up to 14 reference images with stronger identity consistency
Multi-image fusion takes up to 14 reference images. Character identity stays more consistent across multiple editing rounds, helping you build a series from the same visual references.
How to use Nano Banana 2.1

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
