No. As of July 20, 2026, Nano Banana Pro is not free through Google’s current consumer or developer access routes. グーグルの Gemini アプリの利用制限ページ shows that people without a Google AI plan can generate images with Nano Banana 2, but redoing an image with Nano Banana Pro requires Google AI Plus, Pro, or Ultra. Google’s Gemini API pricing page also marks the Nano Banana Pro model’s Free Tier as “Not available.”
The confusion comes from two changes. Google offered limited free Nano Banana Pro quotas when the model launched in November 2025, but that launch arrangement is no longer the current Gemini app flow. Google then introduced Nano Banana 2 in February 2026 as a separate, faster model and made it the default image generator across Gemini’s Fast, Thinking, and Pro modes.
The practical answer is simple: use Nano Banana 2 if you want Google’s current no-subscription image option; pay for a supported Google AI plan if you specifically need Nano Banana Pro in Gemini; or use a paid Gemini API project for programmatic access. A third-party platform like グローバルGPT may offer the model under its own credits or subscription. As an all-in-one AI platform, Global GPT also offers image models like GPT image 2, and Midjourney, でのリサーチと執筆 Perplexity, ChatGPT 5.6, Gemini 3 Pro, and Claude Opus 4.8.

Nano Banana Pro and Nano Banana 2 Are Different Models
Nano Banana Pro is Gemini 3 Pro Image, while Nano Banana 2 is Gemini 3.1 Flash Image. They are not two names for the same product. Google’s current image-generation documentation lists them as separate models: Nano Banana Pro is the premium option for complex visual work, maximum factual accuracy, brand consistency, localization, and precise creative control; Nano Banana 2 is the faster general-purpose model.
That distinction matters when someone says “Nano Banana is free.” They may be referring to free image generation with Nano Banana 2, not free access to Nano Banana Pro. For a closer capability comparison, see our Nano Banana 2 vs Nano Banana Pro guide.
What Is Free in the Gemini App?
People without a Google AI subscription can generate and edit images with Nano Banana 2 in the Gemini app, subject to Google’s standard usage limits. The same official limits page shows no Nano Banana Pro redo entitlement in the “Without a Google AI plan” column.
Google’s February 26, 2026 Nano Banana 2 announcement explains the transition: Nano Banana 2 replaced Nano Banana Pro across Gemini’s Fast, Thinking, and Pro models. Google AI Pro and Ultra subscribers retained Nano Banana Pro for specialized tasks through the image’s three-dot redo menu. Google’s current help table also lists Nano Banana Pro redo for AI Plus.
This means the old claim that every free Gemini user receives a fixed number of Nano Banana Pro generations is no longer reliable. Standard limits can also change with demand and capacity, so a trial, temporary allowance, or rate limit should never be described as permanent free access.
Which Google AI Plans Include Nano Banana Pro?
Google’s current consumer access table lists Nano Banana Pro redo for Google AI Plus, Google AI Pro, and Google AI Ultra. These are paid plans with different overall Gemini limits and benefits. Google localizes availability, storage, included services, and prices by country, so there is no single worldwide subscription price that applies to every reader.
- グーグルAIプラス paid access with higher Gemini limits than the no-plan tier and Nano Banana Pro redo.
- Google AI Pro: paid access with broader Gemini and AI Studio allowances plus Nano Banana Pro redo.
- Google AI Ultra: the highest consumer tier, with the largest overall usage allowance and Nano Banana Pro redo.
A consumer subscription is not the same thing as open-ended API usage. The app entitlement controls what you can do in Gemini, while Gemini API billing is attached to a developer project and follows the API price sheet.
Google AI Studio and Gemini API Pricing
For developers, the current Nano Banana Pro model ID is ジェミニ-3-プロイメージ. As of July 20, 2026, Google’s standard developer pricing lists no Free Tier for this model. The published USD rates are:
| Standard API item | Current published rate |
|---|---|
| Text/image input | $2.00 per 1 million tokens; Google gives an image-input equivalent of about $0.0011 per image |
| テキストと思考の成果 | $12.00 per 1 million tokens |
| 1K or 2K image output | $0.134 per generated image |
| 4K画像出力 | $0.24 per generated image |
| Batch or Flex 1K/2K image output | $0.067 per generated image |
| Batch or Flex 4K image output | $0.12 per generated image |
Those image equivalents cover image output; input images, text, thinking tokens, and optional grounding can add cost. Google’s paid-tier search-grounding allowance—5,000 prompts per month shared across Gemini 3, then $14 per 1,000 search queries—does not make the generated images free.
グーグルの API billing guide says new projects begin on a Free Tier that supports only eligible models. Moving a project to the Paid Tier requires a linked billing account and may require at least $10, or the local-currency equivalent, in prepaid credits. Because Nano Banana Pro has no model-level Free Tier, a general “free API account” does not include free Pro image generation.
ジェミニ-3-プロイメージ.API Quotas and Rate Limits Do Not Mean Free Usage
A price and a quota answer different questions. Pricing determines what successful usage costs. A quota or rate limit determines how quickly or how much a project can use before it receives a limit error.
- Rate limits can include requests per minute, input tokens per minute, requests per day, and images per minute.
- Limits apply per project, not per API key.
- Limits depend on the model, billing tier, spending history, and account standing.
- Google states that published limits are not guaranteed and actual capacity can vary.
- A higher limit allows more throughput; it does not cancel per-use charges.
グーグルの rate-limit documentation was last updated July 3, 2026 and makes this separation explicit. It is also why “I have API quota” and “I have free image credits” are not equivalent statements.
How to Use Nano Banana Pro in Gemini
- Sign in to Gemini with an account that has Google AI Plus, Pro, or Ultra.
- Create an image in the normal Gemini image flow. Nano Banana 2 is the current default model.
- Open the image’s three-dot menu and choose the option to redo it with Nano Banana Pro.
- Compare the new result with the faster Nano Banana 2 version and save the one that better fits the task.
Nano Banana Pro is most useful when factual accuracy, complex layouts, precise text, brand consistency, or detailed 4K output matters more than speed. If resolution is your main goal, our Nano Banana Pro 4K workflow explains the current app and API differences.
What About GlobalGPT and Other Third-Party Platforms?
A third-party platform can provide access to Nano Banana Pro through its own interface, subscription, or credit system. That can be convenient if you want image, video, and language models in one workspace, but it is a separate commercial route—not a free Google entitlement and not a guarante of feature-for-feature parity with Gemini or Google AI Studio.
Before choosing any aggregator, confirm the exact model name, the credit cost per generation, supported resolution, reference-image limits, watermark behavior, data policy, and what happens when promotional credits end. “Free to try,” a signup credit, or a limited campaign is not the same as permanently free use.

Common Access and Billing Problems
I cannot find Nano Banana Pro in free Gemini
That is expected under the current access table. The no-plan tier has Nano Banana 2 image generation, while Nano Banana Pro redo is reserved for paid Google AI plans.
AI Studio asks me to enable billing
Nano Banana Pro’s developer model has no Free Tier. A project must be eligible for the Paid Tier, and the billing account—not the presence of an API key—determines paid access.
The API returns a 429 limit error
A 429 error usually means the project crossed a request, token, image, or spend-based limit. It does not mean the model became free or that charges stopped. Reduce throughput or wait for the relevant window to reset.
A third-party site says Nano Banana Pro is free
Look for the boundary behind the claim: trial credits, a daily cap, reduced resolution, a queue, a promotion, or a paid plan after signup. None of those creates a permanent Google Free Tier.
Nano Banana Pro Free Access FAQ
Is Nano Banana Pro free in the Gemini app?
No. As of July 20, 2026, Google’s access table reserves Nano Banana Pro redo for Google AI Plus, Pro, and Ultra. Accounts without a Google AI plan can generate images with Nano Banana 2 instead.
What Nano Banana model can I use without a subscription?
Nano Banana 2, also called Gemini 3.1 Flash Image, is the current no-subscription image model in Gemini. Standard usage limits still apply, and availability can be reduced during high demand.
Is Nano Banana 2 another name for Nano Banana Pro?
No. Nano Banana 2 is Gemini 3.1 Flash Image, while Nano Banana Pro is Gemini 3 Pro Image. Google positions Nano Banana 2 for speed and general use and Pro for demanding, high-fidelity work.
Does Google AI Studio include free Nano Banana Pro generations?
No model-level Free Tier is listed for ジェミニ-3-プロイメージ. AI Studio can host free-tier projects for eligible models, but Nano Banana Pro requires paid access under Google’s developer billing rules.
How much does the Nano Banana Pro API cost per image?
Google’s standard price is $0.134 for a 1K or 2K output and $0.24 for a 4K output. Input images, text, thinking tokens, and grounding can add cost; Batch and Flex rates are lower.
Does a Google AI subscription include unlimited Nano Banana Pro use?
No. Paid plans provide Nano Banana Pro access with plan-based limits. Google states that Gemini limits can change with capacity, testing, and availability, so subscription access should not be called unlimited.
Are API rate limits the same as free credits?
No. A rate limit is a throughput ceiling, while credits pay for usage. Nano Banana Pro can have an active project quota and still bill every successful request because the model has no Free Tier.
Is GlobalGPT an official Google service?
No. GlobalGPT is an independent third-party platform that offers its own multi-model service. Its credits, subscriptions, features, and limits are separate from Google’s Gemini plans and API billing.
最終評決
Nano Banana Pro is a paid model in Google’s current access structure. Free Gemini image generation now means Nano Banana 2, not a permanent Nano Banana Pro allowance. Choose a Google AI subscription for consumer access, a billed Gemini API project for developer access, or a clearly disclosed third-party plan when a multi-model workspace is more useful. In every case, treat trials, promotional credits, and rate limits as limited access—not proof that Nano Banana Pro is permanently free.
