Earlier this year, Google unveiled its new Gemma 4 models, which became the foundation for its newest on-device AI model, Gemini Nano 4. Google revealed on the Android Developers Blog that the Galaxy Z Flip 8, Galaxy Z Fold 8, and Galaxy Z Fold 8 Ultra run Gemini Nano 4. This means that AI features powered by the model can run entirely on-device without an internet connection. Gemini Nano 4 supports more than 140 languages, improved multimodal inputs, including better text recognition in images and chart reading, stronger reasoning for logic and chain-of-thought tasks, and a larger context window. It is also up to four times faster, uses up to 60% less battery power, and offers better support for agentic AI.
