Phi Silica

Phi Silica appears in Microsoft CEO Satya Nadella on AI’s Business Revolution: What Happens to SaaS, OpenAI, and Microsoft? | LIVE from Davos as Satya Nadella’s example of a resident on-device Microsoft model. He links it to Windows, NPUs, GPUs, and the return of workstation-class local AI.

In the source, Phi Silica is not presented as a replacement for cloud AI. It is part of a hybrid pattern where prompt processing, local context, privacy-sensitive work, and lower-latency actions can happen on the PC while heavier tasks call into Azure or other cloud models.
