On May 20, 2025, Google unveiled Gemma 3n, the latest open AI model designed specifically to run natively on mobile phones, tablets, and laptops—without relying on the cloud.

This new preview model is powerful yet lightweight, with low memory usage and offline capabilities. It’s ideal for developers and users seeking private, fast, and accessible AI directly on their devices.

Introducing Gemma 3n Preview: A Powerful Lightweight AI Built for Mobile Devices

What is Gemma?

Gemma is a family of open AI models developed by Google, built to run seamlessly on both the cloud and personal devices such as laptops or smartphones—without needing constant internet access.

Known for being resource-efficient yet highly capable, Gemma empowers developers and organizations with flexible, private, and fully controllable AI.

Why Gemma 3n Stands Out

High performance on mobile

Gemma 3n is up to 1.5x faster on mobile devices compared to its predecessor (Gemma 3 4B), while using less memory. This improvement is thanks to innovations like Per-Layer Embeddings and a restructured computation architecture.

Dynamic model scaling

With the new Many-in-1 feature, users can switch between 2B and 4B model sizes without downloading multiple versions—offering more flexibility in real-world use.

Enhanced privacy

Gemma 3n processes data locally on the device, without sending information to the cloud. This ensures strong privacy protections and enables offline operation.

Multimodal support

The model can handle multiple input types, including text, speech, images, and video. It also features robust automatic speech recognition (ASR) and speech translation capabilities.

Strong multilingual performance

Gemma 3n excels in multiple languages—especially Japanese, German, Korean, Spanish, and French—with top-tier scores on multilingual benchmarks.

AI on Your Device: A New Experience

Gemma 3n opens the door for real-time, context-aware applications, such as:

Interactive apps that understand images, speech, and user context
On-device data analysis across multiple formats (audio, text, images, video)
Smart transcription, translation, and voice control apps

Built with Responsible AI Principles

Google emphasizes safety, transparency, and ethics in AI development. Gemma 3n has undergone rigorous evaluations around data security, risk management, and responsible deployment to ensure it benefits everyone.

How to Get Started with Gemma 3n

Developers and enthusiasts can explore the Gemma 3n Preview through two main options:

Try online via Google AI Studio – No installation needed, runs directly in your browser
Use locally with Google AI Edge – Ideal for integrating Gemma 3n into real-world applications
