Introduction

Searches like nano banana pricing, nano banana pro price, and nano banana 2 pricing sound simple, but the official developer docs use Gemini model names more often than the product nicknames people actually search.

As of March 17, 2026, Google's official image-generation docs explicitly map Nano Banana, Nano Banana Pro, and Nano Banana 2 into the Gemini image stack. The pricing guide below uses those official mappings together with the Gemini pricing page.

The Pricing Map You Actually Need

Search Term	Official Model Name	Standard Output Pricing
Nano Banana	`gemini-2.5-flash-image`	$0.039 per image at up to 1024x1024
Nano Banana 2	`gemini-3.1-flash-image-preview`	$0.045 per 0.5K, $0.067 per 1K, $0.101 per 2K, $0.151 per 4K
Nano Banana Pro	`gemini-3-pro-image-preview`	$0.134 per 1K/2K, $0.24 per 4K

These brand-to-model mappings now appear directly across Google's image-generation docs and pricing materials.

Official Pricing Details by Model

Nano Banana

The official pricing page lists Gemini 2.5 Flash Image at:

Input: $0.30 for text/image input
Output: $0.039 per image
Batch output: $0.0195 per image

This is the cleanest answer for basic nano banana pricing.

Nano Banana 2

Google's February 26, 2026 launch post identifies Nano Banana 2 as Gemini 3.1 Flash Image. The official Gemini pricing page lists Gemini 3.1 Flash Image Preview at:

Input: $0.50 for text/image input
Output: $0.045 per 0.5K image
Output: $0.067 per 1K image
Output: $0.101 per 2K image
Output: $0.151 per 4K image

That is the best current pricing reference for nano banana 2 pricing.

Nano Banana Pro

The official Gemini 3 guide and Google's product post align Nano Banana Pro with Gemini 3 Pro Image Preview. The pricing page lists:

Input: $2.00 for text/image input
Output: $0.134 per 1K or 2K image
Output: $0.24 per 4K image
Batch output: $0.067 per 1K or 2K image
Batch output: $0.12 per 4K image

That is why nano banana pro price is a different budget conversation from base Nano Banana.

Nano Banana Pricing Comparison

What Changes the Budget Most

The biggest cost drivers are usually:

Model tier
Output resolution
Number of revisions
Whether you are generating from scratch or editing existing images
Whether the team saves prompt templates or improvises every round

Just like Veo, creative teams usually spend more on retries than they expect.

Flow Pricing Is Different from API Pricing

If you use Nano Banana inside Flow, the economics are not the same as direct Gemini API billing.

Google's official Nano Banana 2 post says that in Flow, Nano Banana 2 is the default image generation model and is available to all Flow users for zero credits. That does not mean the Gemini API is free. It means Flow product rules are different from direct API billing.

That distinction matters when people search for nano banana free, nano banana pricing, or nanobanana api interchangeably.

VeoNano Pricing Is Also a Different Layer

VeoNano gives you a product workflow with credits and plan logic. That is not the same as buying image output directly from Google's API pricing table.

So the clean pricing stack looks like this:

Gemini API: official per-image or token-based developer billing
Flow: product-level credits and included capabilities
VeoNano: creator workflow with its own access model

How to Control Nano Banana Costs

The best cost controls are operational.

Start with prompt templates
Use editing instead of regenerating from scratch
Save approved visual directions
Use Pro only when the finish quality justifies it
Use Nano Banana 2 when fast iteration matters more than maximum polish

If your problem is developer integration rather than price, go to the Nano Banana API Guide.

Conclusion

The best answer to nano banana pricing is not one single number. It is a family of current Gemini image prices that map to Nano Banana, Nano Banana 2, and Nano Banana Pro, depending on the quality and speed you actually need.
