## Nano Banana 2.1 examples

Each one came from one 1K request on Nano Banana 2.1, with older Azurade samples as the references.

## Nano Banana 2.1 price

A 1K image costs 2 credits, from $0.04. If a generation fails, the credits go back to your balance automatically.

| Resolution | Nano Banana 2.1, credits per image | Nano Banana 2.1, lowest price per image | Nano Banana 2, credits per image |
| --- | --- | --- | --- |
| 1K | 2 | $0.04 | 4 |
| 2K | 3 | $0.06 | 6 |
| 4K | 5 | $0.10 | 9 |

Prices are at the 500-credit pack, which any paid plan can buy; without a plan the 1,000-credit pack makes a 1K image $0.06. Nano Banana 2 keeps Google Search grounding, which Azurade doesn't offer on 2.1. All plans and packs are on the [prices page](https://azurade.com/prices/).

## Credits work like a deposit

You put money in, you spend it. That is all.

-   Credits never expire, and there is no monthly reset or rollover cap.
-   Subscription credits stack on top of the balance you already have.
-   A failed generation is refunded automatically, without a ticket.
-   Credit packs need no subscription. Buy once, spend whenever.
-   Cancel from your profile without emailing anyone. It runs to the end of the period you paid for, and you see the date.
-   A person answers [support@azurade.com](mailto:support@azurade.com).

The long version of why we will not sell expiring credits is [on the blog](https://azurade.com/blog/expiring-ai-credits/).

## Nano Banana 2.1 questions

The model, what it costs and how to call it.

### What is Nano Banana 2.1?

It's Google's image model for text-to-image and editing, which Google calls the successor to Nano Banana 2. On Azurade AI it runs in the web app and through the API as nano-banana-2.1.

### Is Nano Banana 2.1 better than Nano Banana 2?

Google says 2.1 looks better, follows prompts more closely, renders text more cleanly and keeps a character the same over multi-turn edits. Here a 1K image is 2 credits on 2.1 and 4 on Nano Banana 2, which keeps Google Search grounding.

### How much does Nano Banana 2.1 cost?

2 credits for a 1K image, 3 for 2K and 5 for 4K, so from $0.04 per 1K image with the 500-credit pack, which any paid plan can buy, or $0.06 from the 1,000-credit pack without a plan. Credits never expire, and failed images are refunded automatically.

### Is Nano Banana 2.1 free?

Not unlimited. New accounts get 4 free credits, enough for 2 images at 1K, and after that you buy credits as you go without a subscription.

### How do I use the Nano Banana 2.1 API?

Create a key on your profile page and send model nano-banana-2.1 with your prompt to POST /api/v2/generations, or connect an MCP client to https://azurade.com/mcp. Both bill the balance you use in the web app.

### How many reference images can I send?

Up to 14 per request in the web app and the API. Send them as images to edit, or as references for a character or product that should stay the same.

### Which sizes and aspect ratios does Nano Banana 2.1 support?

1K, 2K or 4K as JPG or PNG, in these aspect ratios: auto (default), 1:8, 1:4, 9:16, 2:3, 3:4, 4:5, 1:1, 5:4, 4:3, 3:2, 16:9, 21:9, 4:1, 8:1.
