What you’ll achieve with this tutorial

Google expanded Gemini’s plans in 2026 and introduced two free usage modes that many people still don’t know about: Nano and Banana. Nano runs the model directly on your device without internet, while Banana is the informal nickname for expanded browser usage without a paid subscription. If you want to use artificial intelligence daily without spending anything, this tutorial shows you exactly how.

Before you start, here’s what you need: a Gemini Nano-compatible Android device (Pixel 6 or newer, plus some Samsung Galaxy S and A series phones launched from 2024 onwards), or any updated browser to access Gemini via web. You also need an active Google account. No Gemini Advanced subscription is necessary for what we’ll show you here.

Understanding the difference between Nano and Banana before you start

The Gemini Nano is Google’s compact model designed to run directly on your device’s hardware, without sending data to external servers. Think of it as an offline version of AI: smaller, faster for simple tasks, and works even without signal. It uses your phone’s processor, specifically the neural processing units (NPUs), which are chips specialized in AI calculations.

The Banana is not an official Google name. This nickname originated in user communities to describe a specific Gemini web configuration that unlocks more features within the free plan, without needing the Gemini Advanced subscription. The name comes from a configuration shortcut that circulated on forums like Reddit and XDA Developers. Google doesn’t officially document this mode, but it works within the platform’s normal terms of service.

Knowing this distinction matters because the two serve different purposes. Nano is ideal for those who want privacy or don’t have stable internet. Banana is better for those who use Gemini on the browser and want to squeeze more from the free plan without paying.

How to enable Gemini Nano on Android

Step-by-step for compatible devices

1. Go to Settings on your Android.
2. Tap Apps and then look for Gemini in the list.
3. Within Gemini app settings, look for the Gemini Nano or On-device model option (the name may vary depending on app version).
4. Activate the corresponding toggle. The system will download the model locally, which may take a few minutes depending on your connection. The file is between 300 MB and 1.5 GB, depending on the device.
5. After download, open the Gemini app normally. When there’s no internet connection, the app will automatically use the local model.

How to know if Nano is active

Within the Gemini chat on Android, look for a discrete indicator at the bottom of the screen or in the chat settings menu. Pixel devices usually display an “On device” label next to responses generated by Nano. On other devices, you can check by disabling Wi-Fi and mobile data: if Gemini continues responding, Nano is working.

If you use AI for studies or productivity, it’s also worth checking the comparison about the best free AI for ENEM 2026 essay writing, which tests tools in the Brazilian educational context.

Devices compatible with Gemini Nano (non-exhaustive list)

• Pixel 6, 6 Pro, 6a and newer versions
• Samsung Galaxy S23, S24, S25 and variants
• Samsung Galaxy A55 and A56
• Some OnePlus and Motorola models with Android 14 or newer

If your device doesn’t appear in Gemini settings with the local model option, it probably doesn’t have compatible NPU. Confirm on Google’s official AI page or in your phone manufacturer’s documentation.

How to use Banana mode on Gemini via browser

What it is and how it works in practice

Banana mode consists of accessing Gemini via gemini.google.com with specific settings that unlock extra features within the free plan. This includes larger context windows (meaning the model can “remember” more text within the same conversation), access to some experimental models that Google makes available on rotation, and more complete integration with free Google Workspace.

Important: Google adjusts these availabilities frequently. What is accessible in the free plan in a given period may change. Always check your Google account settings panel to see which resources are active for you.

Step-by-step to set up Banana

1. Go to gemini.google.com in your computer or mobile browser.
2. Log in with your Google account normally.
3. In the top right corner, click your profile photo and select Gemini Settings.
4. Under Preferred model, check if there are options beyond the default. In 2026, Google started offering experimental versions of Gemini 2.0 and 2.5 to free accounts on limited rotation.
5. Select the available experimental model (when available). The system saves this preference.
6. To maximize context, start a new conversation and, before sending any message, click the conversation settings icon (a gear or adjustment icon, depending on interface version) and activate the expanded context option, if available.
7. Done: you’re using Gemini with Banana mode settings.

What changes in practice

With this mode active, you can paste longer texts for Gemini to analyze, summarize lengthy documents, and maintain more coherent conversations without the model “forgetting” what was said at the beginning. For those who use Gemini for work or study, the difference is noticeable in tasks like reviewing a long report or planning projects with many variables.

Real limitations you need to know

Gemini Nano is considerably less capable than larger models. It responds well to simple summarization tasks, direct questions and short text generation. For complex analysis, extensive code or multi-step reasoning, the local model will frustrate. It’s not a configuration limitation, it’s a matter of model size.

Banana mode, meanwhile, depends on what Google decides to make available for free in each period. The company rotates access to experimental models and can remove or alter features without warning. Users who depend on these features for work should consider whether the paid plan is worth the cost of predictability. Gemini Advanced, which in 2026 continues to be included in the Google One AI Premium package, guarantees constant access to the most powerful models.

Another relevant point for Brazilian readers: Gemini Nano doesn’t yet support Portuguese with the same quality as English in all functions, especially those integrated into Android, like notification summarization and call recording with real-time transcription. These features arrived in Brazil with delays and partial coverage, according to Google communications for the region.

Common issues and how to fix them

Gemini Nano doesn’t appear in app settings The device is probably not compatible, or the app isn’t updated. Go to Play Store, update Gemini and check again. If the option still doesn’t appear, the hardware doesn’t support the local model.

Nano model download gets stuck or fails Make sure you have at least 2 GB of free space in internal storage and a stable Wi-Fi connection. Mobile networks can interrupt downloads. If the problem persists, uninstall Gemini app updates and reinstall from Play Store.

Banana mode settings don’t appear in my account Google does gradual rollouts. Accounts in regions outside the US may receive access weeks later. Keep checking settings periodically. Corporate Google Workspace accounts may have restrictions imposed by the organization’s administrator.

Gemini on browser is responding in English Go to Gemini Settings and check language preference. In some cases, the selected experimental model has limited Portuguese support and the system automatically reverts to English. Select a model with full language support or wait for a Google update.

On-device model uses too much battery AI processing locally requires more from the NPU and, as a result, the battery. If you notice high consumption, limit Nano use to times when your phone is charging or use Gemini via internet when battery is a concern.

Frequently asked questions about Gemini Nano and Banana

Is Gemini Nano more private than online Gemini?

Yes, from a practical perspective. Responses generated by the local model don’t leave the device, which means the text you type doesn’t go to Google servers during processing. However, the Gemini app can still collect usage data and telemetry, as described in Google’s privacy policy. For completely private use, you would need a fully disconnected offline AI model.

Do I need to pay anything to use Banana mode?

No. Banana mode, as described in this tutorial, only uses resources available in Gemini’s free plan. What it does is optimize settings within what Google already offers at no cost. No subscription is necessary.

Does Gemini Nano work without internet on iPhone?

No. Gemini Nano is exclusive to compatible Android devices because it depends on operating system integration and specific chips. On iPhone, Gemini only works via app or browser with active connection. Apple uses its own local models through Apple Intelligence, which is a separate solution unrelated to Gemini.

Do these features work normally in Brazil?

Partially. Gemini Nano arrived in Brazil with support for Pixel devices and some Samsung phones, but features like Portuguese notification summarization were still in expansion phase in early 2026. Banana mode via browser works normally for Brazilian accounts, with the same gradual availability caveats mentioned throughout this tutorial.

Before closing: what’s worth more for you

If your goal is privacy and offline use, enable Nano on your compatible Android and forget about it. It’s simple, works and costs nothing. If you mainly use Gemini on the browser for work or study, setting up Banana mode improves the experience without any additional cost.
