About

Phi-3 Silica is Microsoft's compact language model tailored for the Neural Processing Units (NPUs) in Copilot+ PCs. With 3.3 billion parameters, it is recognized as the smallest in the Phi-3 family, prioritizing efficiency and low power consumption by processing 650 tokens per second using just 1.5 watts. This model operates locally on devices, enhancing privacy by eliminating the need for an internet connection, which helps preserve battery and free up the CPU and GPU. Its deployment enables real-time applications like offline voice assistance, on-device sentiment analysis, and secure voice search, with the promise of personalized tools and APIs through the Windows App SDK as Copilot+ PCs rollout continues.
