Nano Banana AI Image Generator: 2.1, 2 Lite, 2 and Pro
Nano Banana is the name Google uses for its Gemini image models. Zero Kit runs Nano Banana 2.1, Nano Banana 2 Lite, Nano Banana 2 and Nano Banana Pro in one editor.
The four Gemini Nano Banana versions share the same core skills, generating images and editing them from plain-language instructions, and differ in speed, price and precision:
- Nano Banana 2.1 is Google's update to Nano Banana 2, with better visual quality, cleaner text in images and steadier results across several rounds of edits.
- Nano Banana 2, also called Gemini 3.1 Flash Image, is the earlier fast version: pro-level generation and editing at Flash speed, with consistent characters across a series.
- Nano Banana 2 Lite is the fastest and most cost-efficient model, built for quick drafts and high-volume work at a single fixed resolution.
- Nano Banana Pro, or Gemini 3 Pro Image, is built on Gemini 3 Pro for studio-level precision: text in many languages, camera and colour control, relighting and multi-image blends.
On Zero Kit, all four are included in Free and above, run from the same editor and accept reference images, so you can carry a character, a product or a style from one image to the next.
The Nano Banana price per image, the resolutions and the output options differ by version; the table below reads them from the live model list.
Nano Banana image editing works as a conversation. Upload a picture, ask for one change, then ask for the next, and the image keeps everything you did not mention.
That makes the family a natural choice for:
- A character that appears in many scenes.
- A product shown in several settings.
- A room redesigned one step at a time.
Google suggests Pro for high-fidelity work that needs the most accurate result, and the Flash versions for speed and editing.
Among the Flash versions, Google recommends Nano Banana 2.1 over Nano Banana 2 for new work, and 2 Lite where speed and cost matter most.
A practical way to work is to draft on 2 Lite or 2.1, then run the same prompt on Pro when one image has to be exact.
Each version has its own page with sample prompts, a full price table and prompt tips.

Which Nano Banana version should you use?
For series, edits and speed: Nano Banana 2.1
Use Nano Banana 2.1 when you are making several images of the same character or product, editing a photo step by step, adding short text to a design, or exploring ideas quickly.
Nano Banana 2 does the same jobs and is the version 2.1 builds on.
For quick, low-cost drafts: Nano Banana 2 Lite
Use Nano Banana 2 Lite when you need many images fast: drafts, sticker sets, thumbnails, quick colour or background changes.
It is the lowest-cost version, generates at a single fixed resolution and works best with one or two references, so move the final image to 2.1 or Pro.
For precise single images: Nano Banana Pro
Use Nano Banana Pro when one image has to be as exact as possible: small text, fine detail, controlled lighting or a complex scene with many subjects.
The prompt carries over unchanged from the other versions, so a comparison takes one extra run.

Nano Banana FAQ
Nano Banana is Google's name for its Gemini image generation and editing models.
This page covers four of them, all developed by Google: Nano Banana 2.1, 2 Lite, 2 and Pro.
In Google's Gemini app, free users can make images with Nano Banana 2 within usage limits, while Nano Banana Pro comes with Google AI subscriptions, with limited free access in Google Flow.
On Zero Kit it works on the free plan at 1K and 2K, while 4K need Plus or above. New accounts get 10 free credits.
The short version:
- Nano Banana 2.1 and Nano Banana 2 are Google's fast models for generation and editing; 2.1 is the update, with cleaner text and steadier edits.
- Nano Banana 2 Lite is the fastest and lowest-cost version, for drafts and high-volume work at a single fixed resolution.
- Nano Banana Pro is built for precision: accurate small text, fine detail, lighting control and complex scenes.
Google recommends Pro for work that needs the most accurate result.
On Zero Kit, every version is included in Free and above:
- Open the Zero Kit editor, or the page of the version you want, and choose that Nano Banana version.
- Write a prompt, or upload a photo and describe the change.
- Add reference images and, where the version offers more than one, choose a resolution.
- Press generate, then refine with another instruction or rerun the prompt on another version.
Up to 14 in one generation, depending on the version; the table on this page shows the limit for each.
Name each reference in your prompt so the model knows what to take from it.
No. Every Nano Banana model makes still images.
To turn one of them into a short clip, open image to video AI on Zero Kit and pick a video model there.
No. On Zero Kit you use every Nano Banana version with Zero Kit credits: create an account, pick the version in the editor and generate in your browser, with no Google subscription or code to set up.
All versions are included in Free and above. Google itself offers Nano Banana in the Gemini app, Flow and its developer platform.
Outside Google, the closest alternatives are GPT Image 2 from OpenAI and ByteDance's Seedream models, such as Seedream 5.0. Running one prompt on two or three of them shows the difference fastest.
Inside the family, Google positions Nano Banana 2.1 as the fast everyday model and Nano Banana Pro for the most accurate detail and small text.
Yes, on a paid plan. Images and videos made on a paid plan can be used commercially, including product pages, ads and social posts, subject to our Terms. Output from the free plan is for personal, non-commercial use only.
No. We do not use your prompts, uploads or results to train AI models. To run a generation, the prompt and any reference files are sent to the provider of the model you picked, which processes that request under its own terms.
