    AI Glossary

    What is On-device AI?

    Overview

    On-device AI runs models directly on phones, PCs, robots, cars, or edge hardware instead of sending every request to a cloud service. It matters because local inference can reduce latency, improve privacy, lower serving costs, and make AI features work in constrained or offline environments.

    Why it matters

    On-device AI changes the product tradeoff between privacy, latency, cost, battery life, and model capability.

    Where it appears in AI research

    • Mobile and PC AI feature launches
    • Edge inference hardware updates
    • Privacy-preserving assistant designs
    • Robotics and automotive deployments
