What is Gemini Nano AI?


Imagine having an AI assistant that can summarize long conversations, proofread your writing, and suggest smart answers right on your phone – even without an internet connection. That AI-powered future is here with Google’s new Gemini Nano AI model. Designed for on-device execution, Gemini Nano brings the latest advances in natural language processing to the level of consumer devices.

What is Gemini Nano AI?

Gemini Nano is the entry-level model in Google’s Gemini AI family, which also includes the more powerful Gemini Pro and Gemini Ultra versions. While its siblings focus on complex cloud computing capabilities, Gemini Nano optimizes specifically for on-device AI.

Built to run efficiently on mobile hardware, Gemini Nano enables AI features that can work locally on a smartphone or tablet. This avoids the need for constant cloud connectivity. Gemini Nano is currently only available on Google’s latest flagship phone, the Pixel 8 Pro. But expect more devices to integrate Gemini Nano in the next 2-3 years.

Gemini Nano AI features

So what can this on-device AI actually do? Gemini Nano features two key Pixel 8 Pro features so far, with more likely to come:

Summarize in Recorder

In the Recorder app, Gemini Nano provides concise summaries of long recordings, entirely on the device itself. This means that no personal audio data is sent to the cloud. The summaries let you quickly watch long recordings of interviews, lectures, meetings and more – even if you don’t have a network connection at all.

Smart answer in Gboard

Gemini Nano also enables Smart Reply, the automatic writing assistant feature in Gboard. It suggests high-quality responses based on the message context, with significantly improved grammar correction and proofreading capabilities compared to previous implementations. And again, suggestions are generated locally instead of on remote servers.

Why on-device AI is important?

Running AI natively on consumer devices unlocks a number of unique benefits:

Privacy protection

Because data never leaves your phone, Gemini Nano features provide stronger privacy guarantees around sensitive personal content such as messages and audio recordings. This is in line with Google’s privacy-focused ethos.

Consistent responsiveness

Cloud-dependent services experience slowdowns when connectivity fails. In contrast, Gemini Nano’s on-device computations have consistent, deterministic latency that is unaffected by network issues. Features remain snappy and responsive.

Expanding access

As specialized AI hardware becomes cheaper, on-device execution will help democratize advanced AI features. Google plans to bring Gemini Nano to more mid-range and budget devices as well, beyond just their high-end flagships.

Of course, specialized cloud AI will always have an edge in capabilities. But much of that power isn’t needed for consumer applications like grammar correction or in areas like encrypted messaging, where cloud offloading is prohibitively expensive. This makes mobile devices the perfect environment for models like Gemini Nano.

Current applications

If you have a Pixel 8 Pro, you can experience the magic of Gemini Nano here:

Recorder app

Open the built-in Recorder app to transcribe and summarize long audio recordings with just one tap. You can see Gemini Nano spinning around even in airplane mode without connectivity. Tap any part of the waveform to play audio from that point while reading along with the AI-generated transcript.

Generating local transcripts keeps sensitive recordings private. At the same time, chapter-style summaries let you quickly navigate through long files. You’ll wonder how you ever did without this AI assistant!

Smart answers from Gboard

Messages on Android devices have also evolved with Gemini Nano. When you receive a message in an app, Gboard can now suggest full written responses based on context.

And these aren’t just general answers. The AI ​​writing assistant tailors responses specifically to move your conversation forward, with excellent grammar and spelling. Tap to insert a suggestion and then edit freely.

Over time, Gemini Nano’s language model will continue to learn from user interactions. This means even more intelligent Smart Replies understand the nuances of informal dialogue.

Gemini Nano also enables offline dictation and proofreading in Gboard. Even without connectivity, you can compose entire passages with your voice. The AI ​​then cleans up grammar, spelling mistakes, and awkward phrasing once you’re done.

How do you use Gemini Nano AI?

For now, Gemini Nano is limited to Google’s own apps on the Pixel 8 Pro. But Android app developers can also leverage this groundbreaking on-device AI through a special Early Access program.

Registrations are available on the Android Developers website. Once accepted, developers will have access to detailed Gemini Nano documentation, along with code samples and pre-trained models.

Google additionally offers the Android Interface and Composition Engine (AICore) – a toolkit to optimize models like Gemini Nano for mobile. Together, these make integrating efficient on-device AI much easier, even for smaller development teams.

The possibilities extend across sectors, such as:

  • Productivity – Proofreading, voice transcription, audio/text summarization
  • Messages – Smart Replies, Grammar Correction
  • Finance – Analysis of transaction data
  • Gaming – Generating NPC dialogues
  • And much more!

With privacy and speed advantages over cloud AI, expect Gemini Nano integration to quickly spread across all kinds of mobile apps.

The road ahead

On-device AI has reached a tipping point, with Gemini Nano promising to accelerate adoption even further. As the next generation of AI-powered mobility, the potential impacts extend across all sectors.

Transforming the consumer technology landscape

Within 2-3 years, Gemini Nano or similar models will likely power AI assistants across the entire mobile ecosystem. Advanced devices will integrate more advanced successors to Gemini Nano. While mid-range options will get today’s version, bringing AI smarts to more affordable price points.

This proliferation will redefine consumer expectations of how “smart” mobile devices can be. Even without connectivity, they will prove capable of impressive autonomous intelligence.

Privacy implications

By keeping data localized to personal devices rather than sending it to the cloud, Gemini Nano also joins growing calls for data privacy. As consumers become more sensitive to how personal data is used, similar privacy-focused AI approaches will gain traction.

Developer opportunity

For mobile developers, easy access to efficient on-device AI unlocks new potential product features. App stores will soon be rich with AI-enhanced mobile experiences across gaming, productivity, finance and more. Expect a Cambrian explosion of creative use cases!

Generating user trust and engagement in this next app evolution requires thoughtful design around transparency and control. Users need to clearly understand when and how AI is applied. And they must feel empowered to determine the appropriate level of autonomous functioning.


With Gemini Nano AI, Google has lit the fuse for the next platform revolution in mobility. AI will increasingly move from the cloud to the consumer side, with transformative impacts on devices, apps and development ecosystems.

It starts today with the flagship Pixel 8 Pro. But the democratization of intelligence on devices cannot be stopped. In the coming years, expect AI support to permeate every mobile experience.
