Pricing · Pay per image
A pay-per-use AI image generator charges a fixed price for each picture it renders, deducted from a prepaid balance, with no monthly plan and no quota that resets. BananaBanana works that way across the whole catalogue: a draft on Nano Banana 2 Lite costs $0.03, a final on Nano Banana Pro costs $0.11 at 1K or 2K, a 4K render costs $0.20, and whatever you loaded last spring is still on the account today. This page is the price sheet with the arithmetic already done.
Every model on the platform has one price per resolution, from $0.03 for a Nano Banana 2 Lite draft to $0.20 for a Nano Banana Pro render at 4K. GPT Image 2.5 starts at $0.05, Qwen Image 3.0 Pro at $0.04. Two things in the table deserve a second look. Nano Banana Pro costs the same at 1K and 2K, so there is no reason to ever pick 1K on Pro; take the 2K file and downscale if you need to. And 4K is a separate decision, not a default: $0.20 is nearly double, and unless the image is going to print or you plan to crop hard, 2K is what most people should ship.

Prices are per image; reference images are free. A dash means the model does not sell that tier. The same sheet applies on the website, over MCP and over x402.
Generative models fail more often than anyone advertises, and on a per-image system that matters. Here the full price returns to the balance automatically, and a partial block by the safety filter refunds the blocked share. You pay for files you actually received. Nothing else.
Here is the same price sheet turned around, because "how many images is that" is the question people actually ask:
| Balance | Lite drafts ($0.03) | Pro finals, 2K ($0.11) | Pro 4K ($0.20) | Veo 3.1 Lite clips, 4 s silent ($0.10) |
|---|---|---|---|---|
| $1 | 33 | 9 | 5 | 10 |
| $5 | 166 | 45 | 25 | 50 |
| $20 | 666 | 181 | 100 | 200 |
| $100 | 3,333 | 909 | 500 | 1,000 |
Counts are rounded down. $1 is the crypto minimum (USDT on TON or DAI; most other coins start at $1 to $3). Card, PayPal and SEPA start at $20.
A new account also gets $0.20 on signup, which is 6 Lite images, enough to check output quality before you put money in. What the table does not show is how people actually spend. The cheap model does most of the work. Say a product listing needs six hero images. You would typically run 24 drafts on Lite to settle the composition ($0.72), then render the six keepers on Pro at 2K ($0.66). Total: $1.38 for a finished set. If you had done all thirty on Pro, it would be $3.30, and the drafts would look better than they needed to.
That draft-cheap, finish-expensive habit is the single biggest lever on your per-image cost, bigger than any bonus. It also happens to be the opposite of what "unlimited relaxed mode" plans train you to do.
Sticker prices are the whole story only if you top up $10 at a time. Two bonuses sit on top of larger deposits, and they stack:
A $100 crypto deposit with a promo code active credits $120.00. At that point a Nano Banana Pro image at 2K costs about $0.092 and a Lite draft about $0.025. Without a code, $100 credits $110.00 and Pro works out to $0.10 flat. Even a $50 deposit with a code gets $57.50 of balance.
The honest limit: the size bonus is for crypto only. If you pay by card or PayPal, the sticker price is your price, though a promo code still applies. So the "effective $0.092" figure belongs to people who top up $100 or more in stablecoins, which in practice is the heavier users, the ones for whom a cent per image starts to matter. Balances do not expire, and the bonus credit does not either. A $120.00 balance loaded in September is still $120.00 in March if you took a break.
Yes, and at the same prices. The MCP server exposes the same models to Claude, Cursor, Gemini CLI and other MCP clients. You connect with OAuth or an API key, the client calls a tool such as generate_image with a model and resolution, and the exact same $0.03 to $0.20 comes off the same balance. Video works the same way. The quote a tool returns before the job starts is the amount that gets charged; the two numbers are kept identical to the cent on purpose, because an agent cannot eyeball a bill.
For fully autonomous agents there is a second route: an x402 endpoint where a program pays per call in USDC without having an account at all. No signup, no balance, one payment per image. It is niche today, but if you are building something that renders images on a schedule, per-call pricing is the only model that does not force you to babysit a subscription seat. Compare that with plan-based tools, where API access is often a separate, pricier tier, or restricted to the web app entirely. Here the API is not a tier. It is the same price sheet with a different front door.
It is not always the cheaper option, and pretending otherwise would be a bad look on a pricing page.
Subscription tools sell credit bundles, and a fully used top tier can push a top-model image under $0.10. If you reliably clear around 900 Nano Banana Pro images every single month, a plan probably wins on unit price. The tier-by-tier math against one such plan lives in the no-subscription breakdown linked below.
Freemium tools hand out a daily allowance. If a couple of casual images a day is your entire usage and a watermark does not bother you, zero dollars beats three cents. There is no daily free allowance here, only the one-time $0.20.
Some people work by generating forty variations and picking one. On a per-image system that is $1.20 on Lite (fine) or $4.40 on Pro (not fine). Pay per use rewards a bit of intent per prompt, and if that is not how you like to work, a flat plan removes the friction.
The reverse cases are the majority, though: bursty usage, one-off projects, agents, and anyone who has paid for a month they did not use. For those, per-image pricing is not a discount. It is just paying for what you got. We ran the full comparison against one subscription competitor, tier by tier, in the no-subscription breakdown, and the top model gets its own comparison against Google's plans on the Nano Banana Pro price page.
Credits instead of a plan, free daily allowances versus pay per use, and when a subscription actually wins.

Read the guideOn BananaBanana, between $0.03 and $0.20 depending on the model and resolution: $0.03 on Nano Banana 2 Lite, $0.11 for Nano Banana Pro at 1K or 2K, $0.20 for Pro at 4K, and $0.05 to $0.18 for GPT Image 2.5. Failed generations are refunded, so the price applies only to images you receive.
Below roughly 900 top-tier images a month, yes, and by a wide margin at low volume: 20 Pro images cost $2.20 instead of a $10 to $20 plan. Above about 1,000 images every month at steady volume, a fully used top-tier subscription can be cheaper per image.
Because the model renders both from the same budget and the price follows the model, not the pixel count: $0.11 at 1K or 2K. The jump to 4K is a separate, heavier render, which is why it costs $0.20. In practice this means you should never choose 1K on Pro: take the 2K file and downscale if you need a smaller one.
The per-image prices are identical; what differs is the bonus and the minimum. Crypto deposits start at $1 and earn 5% extra balance from $50 and 10% from $100. Card, PayPal and SEPA start at $20 and carry no size bonus, though an active promo code still adds its 10% on any method.
Yes. The MCP server charges the same per-image prices to Claude, Cursor, Gemini CLI and any other MCP client, and an x402 endpoint lets an agent pay per call in USDC with no account.
No. Attaching reference photos is free on every model, and an edit of an existing image is billed as one ordinary generation at the same per-image price. Failed or filtered renders are refunded, so a retry after a block does not cost double.
New accounts start with $0.20 on the balance, 6 Lite drafts to check the output. After that it is $0.03 to $0.20 per image, crypto or card, nothing that renews.
