Microsoft unveils language model Mu for Windows 11
Microsoft just dropped "Mu," a small AI model built into Windows 11 that lets you tweak your settings just by typing what you want—in plain, everyday language.
If you're in the Dev Channel with a Copilot+PC, you can try it now right from the search box.
TL;DR
'Mu' runs directly on your device's neural processing unit
Mu runs directly on your device's Neural Processing Unit (NPU), handling over 100 tokens per second—so it feels quick and smooth.
It learned from hundreds of billions of high-quality examples (thanks to some serious GPU power), building on Microsoft's earlier Phi models to get better at understanding what you mean.
The goal: make changing settings simple, even if you're not techy.
