Is Nano Banana Free? Where It Costs Nothing and Where It Doesn't

Yes, Nano Banana is free in two of Google's own apps: the Gemini app and Google Flow. In the Gemini app you get Nano Banana 2 at no cost, under usage limits Google doesn't publish as a fixed number. Google Flow is more generous on models: without a Google AI plan it allows up to 20 Nano Banana Pro images a day, plus up to 400 a day combined from Nano Banana 2.1 and 2 Lite. Developer routes are a different story. The Gemini API lists no free tier for any Nano Banana model, and Vertex AI is pay-as-you-go.

Here's the short version by surface:

Everything below comes from Google's own pages, checked on October 28, 2026 (the Flow limits on October 29). Google changes these often, so the linked pages win if they disagree with this post.

Which model "Nano Banana" means today

"Nano Banana" started as a nickname and became Google's brand for its Gemini image models. That's why "is nano banana free" has a different answer depending on which one you mean. Google's model deprecations page lists the current family under a "Nano Banana models" heading:

Two status notes, since both models still show up in tutorials:

• Nano Banana 2 is deprecated in the API, not gone. The Gemini API changelog entry for October 6, 2026 released Nano Banana 2.1 and marked gemini-3.1-flash-image deprecated with "no shutdown date announced," telling developers to migrate to gemini-nano-banana-2.1. In the Gemini app, Nano Banana 2 is still the free model.
• The original Nano Banana is on its way out. Google's own pages disagree on the date. The deprecations table lists a March 15, 2027 shutdown for gemini-2.5-flash-image, while a warning on the pricing page names an earlier date. Either way, don't start new work on it.

If you want the feature-by-feature split between the two newest models, our Nano Banana 2 vs Pro comparison covers resolution, reference images, and text rendering. If you're weighing Google against OpenAI, see GPT Image 2 vs Nano Banana. This post sticks to one question: what you pay.

Free Nano Banana in the Gemini app

This is the answer for most people searching nano banana ai free. Open the Gemini app, ask for an image, and it runs on Nano Banana 2. No subscription, no card.

Google's Gemini image generation page labels Nano Banana 2 as the free image model and reserves Nano Banana 2.1, which it calls its "best image generation and editing model," for people with a Google AI plan.

How many free images do you get?

Google doesn't publish a daily image cap. You'll see specific numbers on other sites. None of them come from Google, and they go stale fast.

Here's what Google actually says on its Gemini Apps limits page:

• Limits are compute-based. They depend on the complexity of your prompt, the models and features you use, and the length of your chat.
• Your limit refreshes every 5 hours until you reach a weekly limit.
• Images, music, and video "require a lot of thinking power," so image generation eats into your allowance faster than plain chat.
• Users without a plan get "standard limits." Google AI Plus is listed at 2x, AI Pro at 4x, and AI Ultra at 5x or 20x the AI Pro limits.
• "Limits may change without notice," and if capacity gets tight, free users may be limited before paying ones.

So the honest answer is: limits vary, and Google doesn't give a fixed number. The app warns you when you're close and tells you when your limit refreshes. You can also check under Settings, then Usage Limits.

What a Google AI plan adds

Paying moves you up in two ways: a better model and more room. According to Google's image page and limits page, Google AI Plus, Pro, and Ultra subscribers get:

• Nano Banana 2.1 as their image model
• "Redo with Pro", which reruns any image with Nano Banana Pro from the three-dot menu
• Higher generation limits, at the multipliers above

The Google AI plans page lists the plans and their prices for your country. It also notes that Nano Banana Pro is only available in select countries, so check the country list if "Redo with Pro" doesn't show up for you.

Free Nano Banana in Google Flow

Google Flow is Google's AI filmmaking tool, and it also creates and edits images. Its help page lists these daily image limits for people without a Google AI plan:

The same page says image generation "does not currently use your monthly Google Flow credits or AI credits," so making images doesn't eat into the 50 daily Flow credits everyone gets for video (Flow credits page). Flow's models page names Nano Banana 2 Lite as the default model available at no charge, so pick Pro or 2.1 yourself if you want them.

Note the word "currently." Google can start charging credits for images at any time, so check the Flow page before you rely on these numbers.

Is Nano Banana Pro free?

Yes in Google Flow, within a cap. As covered above, Flow allows up to 20 Nano Banana Pro images a day without a Google AI plan.

Not in the Gemini app. Google's limits page marks "Redo images with Nano Banana Pro" as unavailable without a Google AI plan, and available on Plus, Pro, and Ultra. Free users get Nano Banana 2 only.

Not in the API either. The Gemini API pricing page lists Nano Banana Pro's Free Tier as "Not available" for input and output.

The Google AI plans page says AI Pro and AI Ultra include "AI Studio with expanded limits" for Nano Banana Pro, but that's a paid plan. For nano banana pro free use, Flow is the route. A third-party site promising free Pro images is either spending trial credits or not using Google's Pro model.

Google AI Studio: free interface, paid image models

Google AI Studio is Google's browser workbench for testing Gemini models before you write code. It's where a lot of "use Nano Banana free" guides send people, so this is the surface that causes the most confusion.

Google's Gemini API billing FAQ says "AI Studio usage remains free of charge unless users link a paid API key for access to paid features." Once you link a paid key, AI Studio usage on that key is billed.

The catch is that Nano Banana models are paid features. Every image model on the pricing page shows "Not available" in its Free Tier column. In practice, that leaves you three options:

1. Draft prompts in AI Studio free, then generate the images in the Gemini app or Google Flow.
2. Link a paid API key and pay per image at API rates.
3. Use a Google AI Pro or Ultra plan, which the plans page says includes expanded AI Studio limits for Nano Banana Pro.

The billing FAQ also closes a loophole people ask about. The Google Cloud Welcome credit and free trial credit "can't be used towards the Gemini API or AI Studio." A new Cloud account won't get you free images here.

Nano Banana pricing in the Gemini API

For developers, nano banana pricing is per image, priced through output tokens. The Gemini API pricing page converts that into an approximate cost per image at each resolution. Here are the standard (non-batch) figures at the time of writing:

A few things the table doesn't show:

• Batch mode roughly halves the price for the models that support it, if you can wait for results instead of getting them in real time.
• Nano Banana 2.1 costs less than the Nano Banana 2 it replaces at 1K, 2K, and 4K. That's unusual for an upgrade, and it's one more reason to migrate off the deprecated model.
• Search grounding is billed separately. Google gives a monthly allowance of free search requests shared across Gemini 3 and newer models, then charges per 1,000 requests.
• Input images cost money too, though far less than output.

Rate limits, not just prices

Paying doesn't mean unlimited. Google's rate limits page says limits apply per project, not per API key, and image models carry an extra limit called images per minute (IPM). Your exact limits depend on your usage tier, and you view them in AI Studio. Google also states that "specified rate limits are not guaranteed and actual capacity may vary," so plan headroom if you're generating at volume.

Vertex AI: pay-as-you-go for teams on Google Cloud

Vertex AI is the enterprise route: the same Nano Banana models, billed to a Google Cloud project with Cloud's security, quotas, and data controls. There's no free tier for image generation here either.

The Vertex AI generative AI pricing page lists Nano Banana 2.1, Nano Banana 2 Lite, Nano Banana 2, and Nano Banana Pro, with per-image costs that line up with the Gemini API at standard rates. It also notes that Nano Banana 2.1 doesn't support Flex processing.

Vertex suits companies already on Google Cloud. Solo developers usually get to a working key faster with the Gemini API.

Third-party sites offering "free Nano Banana"

Search free nano banana and you'll find dozens of sites with the name in their URL. Most of them are wrappers: a web app that calls Google's API for you and resells the output. Since Google charges for every API image, "free" on those sites usually means a handful of trial credits before a paywall.

Before you upload anything, check three things:

• Which model it really calls. No Google model ID named means you can't tell if you're getting Nano Banana Pro or something else.
• Where your images go. Uploads pass through a company that isn't Google, under its own privacy policy.
• What "free" covers. Look for the credit count, the resolution cap, and any added watermark. A site called "nano banana something" is not Google.

If you just want free images, the Gemini app and Google Flow give you the same model family with no middleman. For a wider set of options beyond Google, see our roundup of the best free AI image generators.

Watermarks on free and paid images

Every Nano Banana image is marked as AI-generated, whatever you pay. Google's image generation docs state that "all generated images include a SynthID watermark." SynthID is invisible. You can't see it, but Google can detect it. Upload an image to the Gemini app and ask whether Google AI made it.

Images made in the Gemini app also carry a visible watermark. Google's image page says Gemini uses "an invisible SynthID watermark, as well as a visible watermark to show they are AI-generated."

If you need output for commercial work, read the terms for the surface you're using.

Key points

• The Gemini app and Google Flow are the free routes. Gemini app users get Nano Banana 2 under compute-based limits that refresh every 5 hours, up to a weekly cap, with no fixed daily number. Flow lists fixed caps without a plan: 20 Nano Banana Pro images a day and 400 a day combined of 2.1 and 2 Lite.
• Nano Banana Pro is free only in Flow, up to 20 images a day. In the Gemini app it needs a Google AI plan ("Redo with Pro"), and in the API it's paid.
• The Gemini API has no free tier for any Nano Banana model. Prices are per image and scale with resolution. Batch mode roughly halves them.
• AI Studio is free to use, but image models are paid features. Cloud Welcome credit doesn't apply.
• Nano Banana 2.1 is the current recommended API model. Nano Banana 2's API version is deprecated, and the original Nano Banana is being shut down.
• All output carries SynthID. Gemini app images also carry a visible mark.

If you already pay for the API and want image generation inside your coding workflow, the community repos in our Nano Banana Claude skill guide wire it into Claude Code. And if you'd rather start from an image workflow someone already tuned than rebuild prompts every session, Taku lets you mirror a working AI setup into a desktop workspace, remix it, and save it to run again. Taku is in Beta, and the Mac app is available now.
