Google has detailed Gemini Nano 4 for Android, its next on-device AI model. The announcement came alongside the broader Gemma 4 reveal, and it signals a meaningful step forward for the AI features built directly into Android phones.
Here is what we know.
What Is Gemini Nano?
Gemini Nano is Google’s on-device AI model. Unlike the full Gemini models that run in the cloud, Gemini Nano is designed to run entirely on your phone’s hardware. That means it works without an internet connection and processes data locally, which is both faster and more privacy-friendly for everyday tasks.
Previous versions of Gemini Nano powered features like live transcription in the Recorder app, Smart Reply suggestions, and summarisation in Gboard. Gemini Nano 4 is a more capable version of that foundation.
What Does Gemini Nano 4 Bring?
Google has not yet published a full feature list for Gemini Nano 4. However, the model is expected to bring:
- Better context awareness — understanding longer conversations and more complex requests without losing track of what was said earlier
- Improved on-device summarisation — faster and more accurate summaries in apps like Recorder and Google Messages
- More capable smart suggestions — better Smart Reply, better Gboard suggestions, and more nuanced AI writing assistance
- Expanded app integration — more third-party apps will be able to tap into Gemini Nano 4 through Android’s on-device AI APIs
The upgrade matters most if you use AI-powered features regularly. For casual users, the differences may be subtle at first but will grow as more apps adopt the newer model.
Which Devices Will Get Gemini Nano 4?
Google has not confirmed a full device list yet. Based on previous rollouts, Pixel phones are typically first in line, followed by Samsung Galaxy flagships and other Android devices with capable enough chips to run the model locally.
Older phones with weaker chips may not support Gemini Nano 4 at all, since on-device AI requires significant processing power. Devices like the Pixel 9 and Galaxy S26 series should be well-supported.
Why This Matters
Android’s on-device AI capability is growing rapidly. Google Gemini Nano runs without the cloud, which means no latency and no privacy tradeoff. As Google adds more features that rely on this foundation — from call screening to real-time translation — the quality of the underlying model directly affects how useful those features are.
Gemini Nano 4 is also part of Google’s broader effort to close the gap with Apple Intelligence, which has been running on-device AI features through iOS 26.

When Is It Coming?
No specific rollout date has been confirmed for Gemini Nano 4. Given that Google announced it alongside Gemma 4, a wider rollout likely begins in the coming weeks. We will update this as Google confirms more details.
