Is Nano Banana 2.1 free to use?

You can start free on this page: sign in, write a prompt and generate before you pay for anything. Access inside Google's own apps depends on your Gemini plan there, which is separate from the generator above.

How do I use Nano Banana 2.1 online?

Open the generator at the top of this page, write a prompt or press Use It on a gallery card, add reference images in Image to Image mode if you need them, pick an aspect ratio and a resolution, then generate. Download the result or reuse it as a reference for the next edit.

What is the difference between Nano Banana 2.1 and Nano Banana 2?

Nano Banana 2.1 is the direct upgrade. Google points to better visual design and typography, more precise edits that stay inside the area you describe, stronger character and product consistency, and a fix for seams on very wide aspect ratios. Google also plans to retire Nano Banana 2 in its API on October 29, 2026 and names 2.1 as the replacement.

Nano Banana 2.1 vs Nano Banana Pro: which one should I use?

Nano Banana Pro is the premium fidelity tier and can still look better on demanding, detail heavy images. Nano Banana 2.1 is the faster everyday model and scored well on consistency and editing in Google's launch tests. A practical split: draft and iterate on 2.1, then switch the model menu to Nano Banana Pro when one hero image needs the last bit of polish.

How does Nano Banana 2.1 compare to GPT Image 2.5?

They are the current image models from Google and OpenAI. Early leaderboard snapshots put GPT Image 2.5 ahead on overall text to image preference, while Nano Banana 2.1 is built around consistency, multi reference blending and fast edits. Both are in the model menu here, so the useful answer for your project is to run the same prompt through each and keep the better frame.

How many reference images can Nano Banana 2.1 use?

Up to 10 per run in this generator. Google rates the model itself for up to 14 references, with resemblance documented for up to four characters and fidelity for up to ten objects, so a typical setup is one to four people plus the products, outfits or places they should appear with. Upload them in Image to Image mode.

What aspect ratios and resolutions does Nano Banana 2.1 support?

Output comes in 1K, 2K or 4K. Ratios cover 1:1, 2:3, 3:2, 3:4, 4:3, 4:5, 5:4, 9:16, 16:9 and 21:9, plus extreme panoramas at 1:4, 4:1, 1:8 and 8:1. Use 2K or 4K for print and for anything with small text.

Can Nano Banana 2.1 put readable text in images?

Yes, it is one of the main upgrades. Put the exact words in quotes and say where they go. Long paragraphs and very small type at 1K can still blur or misspell, so keep the copy in the image short and render at 2K or 4K when it matters.

Do Nano Banana 2.1 images have a watermark?

Images you download from this page carry no visible watermark. Like every Nano Banana model, 2.1 embeds Google's invisible SynthID marker, which identifies the picture as AI generated without changing how it looks.

Can I use Nano Banana 2.1 images commercially?

Yes. Images you generate here are yours to use in ads, product listings, social posts and client work, and each one stays in your creation history so you can download it again later.

What are the limitations of Nano Banana 2.1?

Google lists a few: small text can blur at 1K, long paragraphs still break, identity can drift over many rounds of edits, left and right are sometimes swapped, and some masked edits are only partly followed. Check spelling and facts before you publish, especially on diagrams and ads.

How It Works

How to Use Nano Banana 2.1 Online in 4 Steps

No install and no API key. Write a prompt, add references if you have them, set the frame, then generate and refine.

Step 11

Writing a prompt in the Nano Banana 2.1 image generator

Write a Prompt or Pick a Case

Describe the subject, setting, lighting and style in plain language, and put any words you want printed in the image inside quotes. Short of ideas? Press Use It on any gallery card above and that prompt lands in the box, ready to edit.

Step 22

Uploading up to 10 reference images for image to image

Add Reference Images If You Have Them

Switch to Image to Image and upload up to 10 pictures: a face to keep, a product to place, a location or a style to follow. Say in the prompt which image is the person, the product or the place.

Step 33

Choosing an aspect ratio and 4K resolution

Set the Aspect Ratio and Resolution

Pick a frame from tall 1:8 to ultra wide 8:1, including 1:1, 4:5, 9:16 and 16:9. Use 1K for quick drafts, then 2K or 4K for the final file or any image with small text.

Step 44

Downloading a finished image and asking for a warmer light

Generate, Refine and Download

Run the prompt and look at the result. To change one detail, reuse the image as a reference and describe only that change. When the frame is right, download it at full resolution.

What Is Nano Banana 2.1?

Nano Banana 2.1 is Google's latest image generation and editing model, released on October 6, 2026 as the successor to Nano Banana 2. In the Gemini API it is called gemini-nano-banana-2.1, and you will also see it written as Gemini Nano Banana 2.1 or nanobanana 2.1. It belongs to Google's fast Flash line, lighter than Nano Banana Pro but built to hold quality on the jobs people run every day. This release focuses on three things: cleaner visual design and typography, edits that change one area and leave the rest alone, and subject consistency, so a person or a product still looks like itself after several rounds of changes.

The Successor to Nano Banana 2

Your existing prompts carry straight over, with sharper text, steadier faces and cleaner edits on the other side.

Built for Iteration

Fast enough to run a prompt several times and keep the best take, which is how most good images actually get made.

One Model for Making and Editing

Text to image and image to image run on the same model, so a draft can turn into an edit without switching tools.

Why Creators Choose Nano Banana 2.1

Six reasons it has become the everyday model for image work.

Fast Enough to Iterate

Flash speed means you can try five versions of an idea while a heavier model is still working on one, then keep the take that works.

Text You Do Not Have to Fix

Titles, labels and captions land readable, so a poster or a thumbnail leaves the generator ready for review instead of a redraw.

Identity That Holds

Faces and products stay recognizable across edits and scenes, which is the problem that used to make AI image series unusable.

Edits That Stay Local

Describe the area to change and the rest of the picture is left alone, so a small fix no longer costs you a good shot.

Free to Start in Your Browser

No Gemini setup, no API key and nothing to install. Sign in, write a prompt and generate your first image in under a minute.

Other Models One Click Away

Nano Banana Pro, GPT Image 2.5, Seedream and more sit in the same model menu, so you can run one prompt through several engines and compare.
