Introducing Mu Language Model And How It Enabled The Agent In Windows Settings
Microsoft, June 23,2025
We are excited to introduce our newest on-device small language model, Mu.
This model addresses scenarios that require inferring complex input-output relationships and has been designed to operate efficiently, delivering high performance while running locally. Specifically, this is the language model that powers the agent in Settings, available to Windows Insiders in the Dev Channel with Copilot+ PCs, by mapping natural language input queries to Settings function calls.
