Nano Banana AI: Google’s Image Generation and Editing Model

Nano Banana is Google’s fast image model for generating and editing pictures, now spanning the original Gemini Flash Image release, Nano Banana 2, and Nano Banana Pro. Run all three on the FLORA canvas.

Want to try it? Nano Banana, Nano Banana 2 and Nano Banana Pro all run on the FLORA canvas, so you can compare the three on the same prompt before picking one. Start free on FLORA.

What is Nano Banana?

Nano Banana is the nickname for Google’s Gemini Flash Image models. It takes a text prompt, a reference image, or several images at once, and returns a new image. What sets it apart from most image models is that it is edit-first: you can hand it a photo and describe a change in plain language rather than regenerating from scratch.

Three versions matter today. The original, Gemini 2.5 Flash Image, is the fastest at around 20 seconds. Nano Banana 2 runs on Gemini 3.1 Flash Image and pushes quality up to 4K. Nano Banana pro is the premium tier, built for multi-image composition with up to 14 reference images. Google Nano Banana is proprietary, so there is no self-hosted option, and all three are available inside FLORA.

Quick facts

• Modes: Text → Image · Image → Image (editing) · Images → Image (multi-image).

• Speed: around 20s on the original, ~30s for edits, ~80s on Nano Banana 2, ~30 to 40s on Pro.

• Resolution: 1K, 2K and 4K on 2 and Pro. The original defaults to 1024x1024.

• Aspect ratios: Pro supports 21:9, 16:9, 5:4, 4:3, 3:2, 1:1, 2:3, 3:4, 4:5 and 9:16. The original inherits the ratio of the first image you connect.

• Reference images: up to 14 on 2 and Pro.

• Training / licensing: proprietary Google model. Text moderation follows Google’s usage policies.

What it’s great for

• Fast photo edits and stylized generation.

• Nano Banana image editing where you want a targeted local change, not a new picture.

• Multi-image fusion, compositing several references into one frame.

• Turning photos into collectible or toy-style renders.

Nano Banana versions

Three builds are live. The original Gemini 2.5 Flash Image is the quickest, around 20 seconds, and still the best choice for a small edit. Nano Banana 2 runs on Gemini 3.1 Flash Image, pushes output to 4K and can ground a generation in a web search, with a lighter sibling for cheaper runs. Gemini 3 Nano Banana Pro is the quality tier: the same editing behaviour, ten aspect ratios and much stronger multi-image composition. All three are available in FLORA, and this page tracks whichever is current.

Prompt tips

• For edits, prefix with “Edit:” and describe pixel-accurate changes.

• Use clear style tokens such as “photoreal”, “3D figurine” or “studio lighting”.

• Add a seed when you need the same result twice.

• On multi-image runs, say what each reference contributes rather than listing them.

Running Nano Banana in FLORA

On the FLORA canvas Nano Banana sits as an image block, so a prompt or a reference photo feeds it directly and the result flows onward without leaving the board. That is the difference from using a Nano Banana AI image generator on its own: the edit becomes one step in a workflow you keep.

Because it is edit-first, it pairs naturally with the techniques that clean an image up. Pull a subject out with the background remover, change colourways with product recolor or image recolor, swap materials using texture matchers, shoot a clean plate with studio shot, then finish with the image upscaler.

Models are interchangeable on the canvas, so you can run the same prompt through Nano Banana and a rival and compare. Try it against Seedream or Flux, or read our ranking of the best AI image generators. Specs live in the Nano Banana Pro docs, and you can open a canvas and try it free.

Nano Banana FAQs

Is Nano Banana free?

You can try it without paying by starting on FLORA’s free tier, which lets you run Nano Banana AI free alongside other image models before committing budget. Beyond that, cost scales with resolution and version: 4K on Pro costs twice a standard run, and Nano Banana 2’s web search adds a flat fee.

What is the difference between Nano Banana, 2 and Pro?

The original Gemini 2.5 Flash Image is fastest at about 20 seconds. Nano Banana 2 moves to Gemini 3.1 Flash Image with 4K output and optional web grounding. Pro is the quality tier, with ten aspect ratios and the strongest multi-image composition.

Who makes Nano Banana?

Google. It is the informal name for the Gemini Flash Image family, and gemini Nano Banana or Nano Banana Google both refer to the same models. It is proprietary, so there is no open-weights version.

How many reference images can it take?

Up to 14 on both 2 and Pro. That is what makes Nano Banana Pro AI image generator runs useful for composites, where several products or people need to share one frame and one lighting setup.

Is it better for editing or for generating from scratch?

Editing. Plenty of models generate a good first image, but Nano Banana is unusually good at changing one thing in a picture you already have while leaving the rest alone.

Safety
