01What it is

What is Nano Banana 2?

Nano Banana 2 is the popular name for Gemini 3.1 Flash Image, the fast tier of Google DeepMind's image generation stack. It consistently ranks in the global top 2–3 for photorealism while generating in seconds rather than minutes, and it covers the full working range: text-to-image, image editing, and reference photos for consistent characters and products. On BananaBanana you use the production model through a simple web generator: pick a resolution from 512px to 4K, generate up to 8 variations per prompt, and pay a flat per-image price from your crypto balance. No monthly plan, no credit card, no Google account — the balance you top up never expires.

How much does Nano Banana 2 cost?

On BananaBanana, Nano Banana 2 costs from $0.03 per image at 512px, $0.06 at 1K, $0.09 at 2K and $0.13 at 4K — pay-as-you-go, with no plan gating the model. For scale: a $5 top-up buys about 80 one-megapixel images. Siblings share the same balance — Nano Banana 2 Lite at a flat $0.03 for drafts and bulk runs, and Nano Banana Pro from $0.11 for studio work. Top-ups start at $1 in USDT, USDC, BTC, ETH, SOL, TON and other coins, with +5% bonus from $50 and +10% from $100. See the full pricing page for every model.
