Nano Banana 2 vs Nano Banana Pro: which one to choose
The Nano Banana family — Google's image generation models from the Gemini line — has two top versions: Nano Banana 2 (Gemini 3.1 Flash Image) and Nano Banana Pro (Gemini 3 Pro Image). Both are available on NeuralBox, and both keep raising the same question: which one should you use?
The short answer: for most tasks, Nano Banana 2 — it's cheaper and accepts more references. Pro is the one to pick when the image needs correct text or maximum detail. Below is a detailed comparison with prices.
What they have in common
Both models generate images from text and from references, support resolutions up to 4K, PNG and JPG output and 10 aspect ratios — from square to cinematic 21:9. Prompts work in any major language.
Both are available in the web interface and through the NeuralBox API. There is no subscription: you top up your balance by card (via Stripe) or with crypto and pay per generation. For very simple, high-volume tasks, don't forget the base Nano Banana — it costs about $0.03 per image.
How they differ
The main differences are price, the number of references and text handling. Prices are on the Basic plan ($5 = 150,000 tokens); on higher plans tokens are up to 40% cheaper. For comparison, the table also shows the official Gemini API prices.
| Nano Banana 2 | Nano Banana Pro | |
|---|---|---|
| Based on | Gemini 3.1 Flash Image | Gemini 3 Pro Image |
| Price, 1K | ≈ $0.067 ($0.067 in the Gemini API) | ≈ $0.15 ($0.134) |
| Price, 2K | ≈ $0.10 ($0.101) | ≈ $0.15 ($0.134) |
| Price, 4K | ≈ $0.15 ($0.151) | ≈ $0.20 ($0.24) |
| References | up to 14 | up to 8 |
| Text on images | — | yes: posters, banners, infographics |
| Strong point | speed and price, consistent characters | maximum detail, complex scenes |
When to use which
The rule is simple: start with Nano Banana 2 and switch to Pro only for a specific reason.
How to try it
Sign in with Telegram, Google or email, top up your balance (from $5 by card, from $2 in crypto) and open the Images tab — both versions are in the model list.
