01:33 PM EDT, 06/23/2025 (MT Newswires) -- Microsoft ( MSFT ) said Monday it launched an on-device, task-specific small language model called Mu that powers the artificial intelligence agent recently added to the Windows settings menu for task automation.

The encoder-decoder language model, available to Windows Insiders in the Dev Channel with Copilot+ PCs, is offloaded onto the neural processing unit and responds at over 100 tokens per second, analyzing natural language queries to execute Windows Settings function calls, according to the company.

Mu addresses the limitations of NPUs and was trained using A100 graphic processing units on Azure Machine Learning in phases, the company said.

Shares of Microsoft ( MSFT ) were up 1.3% in recent trading.
