Nano Banana AI: Google’s Image Models and How to Try Them
Nano Banana is the name Google uses for its Gemini image models. Google documents Nano Banana 2, Nano Banana 2 Lite and Nano Banana Pro.
Sources reviewed October 30, 2026: Google’s Gemini 3.1 Flash Image documentation and Google’s June 30, 2026 Nano Banana 2 Lite announcement.
Which models are called Nano Banana?
| Name | Google model | What Google positions it for |
|---|---|---|
| Nano Banana Pro | Gemini 3 Pro Image | Complex professional work where accuracy matters more than speed. |
| Nano Banana 2 | Gemini 3.1 Flash Image (gemini-3.1-flash-image) | General image generation and editing that balances quality, speed and cost. |
| Nano Banana 2 Lite | gemini-3.1-flash-lite-image | Fast, lower-cost images. Google cites about 4 seconds for a text-to-image result. |
| Nano Banana | Gemini 2.5 Flash Image | The original, now a legacy model. Google suggests Nano Banana 2 Lite as its replacement. |
Our model menu also lists Nano Banana 2.1. That label comes from our image service provider; the Google pages reviewed above do not document it, so we do not describe its specifications here.
One prompt, six image models
We gave each model option on this site the same short description: a terracotta teapot on a linen-covered table by a window. These are single, unedited results, so they show differences in style and framing, not a quality ranking.
Nano Banana 2.1
Wide window view, a small cup on a wooden tray and loose tea leaves.
Nano Banana 2
Closer framing, a garden behind the glass and a cup on a wooden saucer.
Nano Banana Pro
A weathered glaze, plus a mug and a bowl of lemons it added on its own.
GPT Image 2.5
Strong sunlight and clean shapes, with a bowl of tea and a sprig of leaves.
GPT Image 2
Soft backlight, white blossoms in a vase and a tea bowl on a tray.
Seedream 5.0 Pro
The most minimal take: the teapot alone, with a softly blurred window.

Nano Banana, Imagen and ImageFX
ImageFX was a Google Labs tool that launched in February 2024 with Imagen 2. In February 2026 Google announced that ImageFX capabilities were moving into Flow. Imagen and Nano Banana are separate model families: Imagen powered the original ImageFX, while Nano Banana is the name Google now uses for its Gemini image models.
