Gemini Nano on device — Florina Muntenescu & Oli Gaymond, Google DeepMind
May 22, 2026 · 19:38
Florina Muntenescu and Oli Gaymond from Google DeepMind explain Gemini Nano, an on-device model that ships at 3–4 GB and is shared across apps via the AI Core system service, which handles scheduling, queuing background batch jobs overnight, and prioritizing foreground apps. The MLKit GenAI APIs (prompt API for text/image input, text output) give access to Gemini Nano, but require flagship devices from the last two years for optimal performance; classic MLKit (vision, OCR) runs on over a billion devices. Hybrid inference, launched weeks before this talk, automatically falls back to Gemini Flash in the cloud when the on-device model isn't available, extending reach. An embedding API for RAG-style solutions is coming soon. For fully custom models, LiteRT offers an alternative path but requires more developer effort for testing and optimization.
