What Is Nano Banana 2.1?
Nano Banana 2.1 is Google's image generation and editing model, released on October 6, 2026. It replaces Nano Banana 2 and is positioned as the more efficient counterpart to Nano Banana Pro.
Here you use the same model from a browser, with no API key and nothing to install, so you can go from a rough idea to a usable poster, product shot or portrait in one place.
What's New in Nano Banana 2.1
Google's model card compares 2.1 with earlier Nano Banana models in side-by-side human preference tests. These are the changes you will notice first.
Sharper text and infographic layouts
Headlines, labels and infographic layouts come out cleaner than before. In Google's preference tests, 2.1 scores 1048 Elo for infographic design, against 961 for Nano Banana 2.
Multi-reference image fusion
Combine up to 14 reference images in one prompt: up to 10 objects kept at high fidelity and up to 4 characters whose faces and outfits stay recognizable.
Consistent multi-character scenes
Multi-character consistency is the biggest jump in Google's evaluation: 1106 Elo, up from 978 for Nano Banana 2. Faces and outfits hold steady when the same people appear in new scenes.
Sketch and semantic mask editing
You don't need to paint a pixel mask. Circle an area with a rough sketch or describe it in words, and the edit stays inside that region while the rest of the image is preserved.
Ultra-wide 8:1 and 1:8 aspect ratios
Wide (8:1, 4:1) and tall (1:8, 1:4) frames are supported, and the tiling artifacts earlier models showed at 2K and 4K are fixed, so long website banners and panoramas are practical.
Native 1K, 2K and 4K output
Images render directly at 1K, 2K or 4K with no upscaling step. A 4K square is 4096 × 4096 pixels, and an 8:1 banner at 4K reaches 12288 × 1536.

What You Can Create with Nano Banana 2.1
Each example pairs a Nano Banana 2.1 use case with the idea behind its prompt, so you can adapt it to your own work.
E-commerce product photo editing
Prompt idea: List the changes (emerald green liquid, a new "VERT No.9 - MILANO" label) and then the things to keep: bottle shape, marble pedestal, lighting and camera angle.
Portrait relighting
Prompt idea: Give the direction and color of each light, for example blue from the front and warm amber from behind, and ask to keep the person, pose and framing unchanged.
Group photos from separate portraits
Prompt idea: Upload one clear portrait per person, then describe the shared scene and action in a single line, such as "An office group photo of these people, they are making funny faces."
Reverse angles and new viewpoints
Prompt idea: Ask for the same scene from behind the subject and say where the window and sofa should end up, so the room stays consistent from the new angle.
Realistic landscape photography
Prompt idea: Combine an aerial camera angle, golden hour light, autumn forest color and one small focal subject such as a red car. The same approach works for wide banners.
Nano Banana 2.1 Prompt Tips
These habits make text sharper and keep subjects consistent from one image to the next.
- 1
Quote the exact text
Put signage and labels in quotation marks, such as "MARKET", and say where each line sits in the layout.
- 2
Use 2K or 4K for fine text
Small lettering and dense infographics come out cleaner at 2K or 4K than at 1K.
- 3
Say what changes and what stays
When editing, name the elements to change and list the surfaces, shapes and lighting that must stay the same.
- 4
Number your references
Refer to uploads by order, for example "the coat from image 1 on the character from image 2".
- 5
Rewrite the layout for 8:1
For panoramas, describe a left-to-right sequence instead of reusing a prompt written for 16:9.
- 6
Describe what you want to see
Write "an empty cobblestone street at dawn" rather than listing what should be missing.
- 7
Use camera language
Focal length (85mm, 35mm), aperture (f/1.8) and light direction steer realistic shots.
- 8
Draft at 1K first
Settle the composition at 1K, then spend credits on 2K or 4K for the final version.
- 9
Combine edits into one prompt
Group related changes into a single instruction so the image does not drift over many rounds.
