If you are trying to buy a "Nano Banana 2 subscription", start here: Google does not sell one. Nano Banana 2 is the image model inside the Gemini app, and it runs on every tier, including the free account. What you can pay for is a Google AI plan, which raises your overall Gemini usage limit and unlocks a few image-specific extras. As of September 22, 2026, the US prices on Google's own subscriptions page are Google AI Plus at $4.99 a month, Google AI Pro at $19.99, and Google AI Ultra at $99.99 or $199.99 depending on which usage tier you pick.
Two other things change what you should buy. Sites selling a "Nano Banana subscription" with their own credit packs are third-party wrappers, not Google, and the ones examined below do not say which model produces your images. And if you need several hundred images a month, 4K output, or anything automated, no Google plan is the right product: the per-image API is, and the break-even sits around 300 images a month against the Pro plan.
What Google actually sells, and what it costs in the US
Every price below is monthly, personal-account, US, as displayed on Google's subscriptions page on September 22, 2026. Annual billing, tax and any promotion appear only in the signed-in checkout, so do not treat these as the final receipt.
| Plan | Monthly price (US) | Gemini usage limit | Storage | Google Flow credits |
|---|---|---|---|---|
| Free | $0 | Standard | 15 GB | limited |
| Google AI Plus | $4.99 | 2x Free | 400 GB | 200 |
| Google AI Pro | $19.99 | 4x Free | 5 TB | 1,000 |
| Google AI Ultra | $99.99 | 5x Pro | 20 TB | 10,000 |
| Google AI Ultra | $199.99 | 20x Pro | 20 TB+ | 25,000 |
College students in the US get Google AI Pro free for one year, which is the only way to get a paid tier without paying.
Notice what is missing from that table: an image count. Google's usage-limits page says Gemini limits are "compute-based" and "factor in the complexity of your prompt, the models and features you use, and the length of your chat". The pool refreshes every five hours until you hit a weekly ceiling. Image generation draws from the same pool as everything else you do in Gemini, and Google prints no images-per-day number for any tier. Any "price per image" you see quoted for a Google AI plan is someone's arithmetic, not a Google figure.
What each tier changes for Nano Banana 2
The image-specific differences are narrower than the price gaps suggest. This is what Google's image help page and the usage-limits page document, tier by tier.
| Nano Banana 2 feature | Free | Plus $4.99 | Pro $19.99 | Ultra $99.99 / $199.99 |
|---|---|---|---|---|
| Generate with Nano Banana 2 | Yes | Yes | Yes | Yes |
| Usage pool vs. Free | 1x | 2x | 4x | 5x Pro / 20x Pro |
| Download resolution | 1K | 2K | 2K | 2K |
| Redo with Nano Banana Pro | No | Yes | Yes | Yes |
| Nano Banana Pro as the model (selector on Pro) | No | Yes | Yes | Yes |
| AI Mode image creation in Google Search | 25 per 24h | 50 | 100 | 1,000 |
Read the rows this way:
Free already gives you Nano Banana 2 itself, at 1K download resolution, inside a standard usage pool. Most people looking for a subscription are hitting that pool, not a hard image cap.
Google AI Plus at $4.99 is the tier that changes the most per dollar for image work. It doubles the pool, lifts downloads from 1K to 2K, and turns on Redo with Pro, the button that re-renders a Nano Banana 2 result with Nano Banana Pro. If you only care about images and you are hitting free limits a few times a week, this is the plan to buy.
Google AI Pro at $19.99 doubles the pool again (4x Free), and brings the non-image extras: 5 TB of storage, 1,000 Flow credits for video, YouTube Premium Lite, and higher access to Gemini's Pro model. For images alone, the difference from Plus is the pool size and the AI Mode allowance (50 to 100). If you would use the storage or Flow anyway, Pro is easy to justify; if not, Plus covers the image features.
Google AI Ultra at $99.99 (5x Pro) or $199.99 (20x Pro) exists for people who exhaust Pro's 4x pool regularly. Image generation is one of the heavier features, so heavy generators do land here. But at that volume you are also in the range where the per-image API costs less, which the break-even section below quantifies. Ultra makes sense when you want that volume inside the Gemini interface and the 20 TB of storage; it does not make sense as a pure image budget.
One rule applies on every paid tier: Google says that "if you reach your daily quota of Nano Banana 2 images, you can't redo any additional images with Nano Banana Pro". So there is a daily image quota underneath the compute pool, Google just does not publish the number. Paid tiers multiply the pool; nothing makes it unlimited.
Why other pages quote $7.99, $249.99 or a 20/50/100 images-per-day table
Google changed these prices twice in 2026, and most published guides were written before at least one change.
Google AI Plus launched in the US on January 27, 2026 at $7.99 a month with 200 GB of storage, per Google's launch post. On June 8, 2026, Google announced a cut to $4.99 with storage doubled to 400 GB, applied at the next renewal, as reported by 9to5Google. Any page showing Plus at $7.99 is describing the launch price.
Google AI Ultra was a single $249.99 tier. At I/O on May 19, 2026, Google added the $99.99 tier at 5x Pro limits and cut the top tier to $199.99, per Google's I/O post. Pages quoting $249.99 predate that; $124.99 and $49.99 match nothing on Google's current price list.
The images-per-day table is a different kind of staleness. Earlier in 2026 Google's Gemini image help printed 20, 50, 100 and 1,000 images per day for Free, Plus, Pro and Ultra. That table has been removed and replaced by the compute-based description above. The similar-looking 25 / 50 / 100 / 1,000 figures that still exist are for AI Mode in Google Search, a separate product with its own daily counter, not for the Gemini app. Our Nano Banana 2 limits guide explains what the compute-based limit means in practice, on the app side and the API side.
How to "get a Nano Banana subscription" the official way
Since the product you are buying is a Google AI plan, the steps are Google One steps, and the Nano Banana 2 part is just choosing a model afterward.
- Use a personal Google Account. Google's AI Pro membership help says you cannot sign up if you are already subscribed through a third-party partner or Pixel Pass, and Workspace accounts follow their own admin rules.
- Open the subscriptions page (gemini.google/subscriptions or the Google One plans page) and pick Plus, Pro or Ultra. Monthly and annual billing are both offered; the annual total and tax show at checkout.
- In the Gemini app, the model selector decides which image model you get: Flash-Lite routes to Nano Banana 2 Lite, Flash or Pro routes to Nano Banana 2, and Pro with a Google AI plan gives you Nano Banana Pro directly.
- To upgrade a Nano Banana 2 result, open More at the bottom right of the image and choose Redo with Pro. This needs Plus or higher and stops working once you reach the day's Nano Banana 2 quota.
- If you run out of pool on Pro, Google lets you buy AI credits for extra usage rather than jumping to Ultra. Cancelling removes the Pro Gemini features and the expanded storage at the end of the billing period.
Nothing in these steps mentions a watermark. None of Google's help pages say whether a paid plan changes the visible mark on generated images, so treat any "watermark-free with a subscription" claim as unverified.
Wrapper "Nano Banana subscriptions" are not Google plans
Sites such as nanobanana.io, with its "Plans & Pricing" page, and several similar domains are not Google. They sell real subscriptions, but they are a different product from a Google AI plan, and the difference matters before you enter a card number.
| Seller | Plans (as displayed 2026-09-22) | What you get | Model disclosed? |
|---|---|---|---|
| Google (gemini.google) | Plus $4.99, Pro $19.99, Ultra $99.99 / $199.99 | Gemini app, 2K downloads, Redo with Pro, storage, Flow credits | Yes: Nano Banana 2 / Pro by name |
| nanobanana.io | Basic $9.90 "flash sale" (regular $19.90), Pro $23.90 (regular $47.90), Enterprise $63.90 | Yearly credit pools of roughly 750 / 1,800 / 6,000 images; lists "Nano Banana Pro" and "Seedream"; watermark-free downloads | No affiliation statement, no model ID |
| nano-banana2.org | Starter $4.99/mo annual ($19.99 monthly), Pro $11.99 / $89.99, Premium $44.99 / $179.99 | Credits, "4 credits can generate 1 high-quality image"; crypto payments accepted | No affiliation statement, no model ID |
Three checks separate a wrapper from Google:
The domain. Google's plans live only on gemini.google or one.google.com, and checkout runs through your Google Account. Any site with its own login and "credits" is a wrapper.
The model. A wrapper that lists "Nano Banana Pro" alongside "Seedream" is running several models behind one interface; the page does not tell you which one made your image. Google's app names the model in the selector.
The price per image. nanobanana.io's Basic plan at $9.90 works out to roughly 750 images a year, about 62 a month. Google AI Plus at half that price gives you a usage pool that, for most hobbyists, produces more than 62 images a month, plus 2K downloads and 400 GB of storage. Wrappers can still be the right buy if you want a specific editing interface or bundled models, but not because they are cheaper Nano Banana 2.
Whatever a wrapper says, no plan from anyone is unlimited Nano Banana 2, and the sale prices on these pages are limited-time offers, so the numbers above are what the pages showed on September 22, 2026.
When pay-per-image beats a plan
The consumer plan is a bundle with a compute pool; the API is a meter. Once you know your monthly image count, the comparison is arithmetic.
Google's Gemini Developer API pricing lists Nano Banana 2 as gemini-3.1-flash-image with no free tier. Standard output costs $0.045 per 0.5K image, $0.067 per 1K, $0.101 per 2K and $0.151 per 4K; Batch halves that to $0.034 per 1K and $0.076 per 4K. Input tokens are billed separately at $0.50 per million. Nano Banana 2 Lite (gemini-3.1-flash-lite-image) is $0.0336 per 1K image and Nano Banana Pro (gemini-3-pro-image) is $0.134 per 1K or 2K image and $0.24 at 4K. The API pricing guide walks through the token math if you need it.
The LaoZhang API gateway offers the same three models on a flat per-call price: gemini-3.1-flash-lite-image at $0.025 per image, gemini-3.1-flash-image at $0.055 per image, and gemini-3-pro-image at $0.09 per image, pay-per-use through /v1/chat/completions on https://api2.laozhang.ai/v1. It is an OpenAI-compatible developer endpoint, not a plan reseller, so it suits scripts and apps rather than the Gemini app itself. The docs page does not list resolution options, so confirm the quote in the console before you scale a batch.
Dividing each plan price by a per-image rate gives the point where the API would have delivered the same count for the same money:
| Monthly budget | Official API, 1K Standard ($0.067) | Official API, 1K Batch ($0.034) | LaoZhang ($0.055) |
|---|---|---|---|
| $4.99 (Plus) | about 74 images | about 147 | about 90 |
| $19.99 (Pro) | about 298 | about 588 | about 363 |
| $99.99 (Ultra 5x) | about 1,492 | about 2,941 | about 1,818 |
| $199.99 (Ultra 20x) | about 2,985 | about 5,882 | about 3,636 |
These are break-even illustrations, not the plan's cost per image. The plan also buys storage, Flow credits and text usage, and its image pool is compute-based rather than a fixed count. The API side excludes input tokens and any calls you discard.
Applied to real situations:
You generate images by hand in Gemini, want 2K downloads, and stay under a couple of hundred images a month: buy Plus, or Pro if you also want the storage and Flow credits. The API would cost about the same and give you a worse interface.
You need more than roughly 300 finished 1K images a month, or any 4K output, or you are calling the model from a script, a Zapier flow or a product: use the API. At 1,000 images a month, official Standard pricing is about $67, Batch about $34, and LaoZhang about $55, all well under the $99.99 Ultra tier that would otherwise be your next step. Use Google's official key if you want Batch pricing and Google's own billing; use LaoZhang if you want a flat per-call price on an OpenAI-style endpoint without token accounting.
You have both a plan and an API key: they are two separate purchases. A Google AI plan does not raise your API quota or discount API calls, and API spend does not touch the Gemini app pool.
Frequently asked questions
Is Nano Banana 2 free and unlimited?
Free, yes: Nano Banana 2 is available in the Gemini app without a plan, at 1K download resolution. Unlimited, no. Free accounts draw from a standard compute pool that refreshes every five hours up to a weekly limit, and Google also references a daily quota of Nano Banana 2 images. Paid plans multiply the pool; none removes the limit. What is free and what is paid covers the 1K versus 2K line in more detail.
How do I get a Nano Banana subscription?
Buy a Google AI plan on gemini.google/subscriptions with a personal Google Account, then use Gemini with the model set to Flash or Pro. In the US on September 22, 2026 that means Plus at $4.99, Pro at $19.99 or Ultra at $99.99 / $199.99 a month. There is no separate Nano Banana product to subscribe to; any site offering one under its own login is a third-party wrapper.
How much does Nano Banana 2 cost per month?
Zero if the free pool and 1K downloads are enough. $4.99 for Plus buys double the pool, 2K downloads and Redo with Pro, and is the right first step for most people who hit free limits. $19.99 for Pro quadruples the pool and adds storage and Flow credits. Beyond that, a per-image API budget of $20 to $70 a month typically covers more images than Ultra would.
Does a Google AI plan increase my API limits?
No. Gemini app plans and the Gemini Developer API are separate products with separate billing. The API has no free tier for Nano Banana 2 and charges per image regardless of what plan your consumer account has, and a paid API key does not enlarge your Gemini app pool.
Is Google AI Ultra worth it for image generation?
Only if you want very high volume inside the Gemini interface and value the 20 TB of storage. For the images themselves, $99.99 buys about 1,500 Nano Banana 2 images a month on the official API at 1K, or nearly 3,000 on Batch, with 4K available. If you are close to exhausting Pro's 4x pool, price the API first. The Nano Banana Pro vs Nano Banana 2 comparison helps decide whether the Pro model is what you actually need.
