Microsoft unveils Mu AI model for Windows PCs

Microsoft just dropped Mu, a fresh AI model built to make Windows PCs run smoother.
Part of Copilot+, Mu handles tasks right on your device—no cloud needed—so things feel quicker and more responsive.
If you're on the Windows Insider Dev Channel, you might already see it in the Settings app.

TL;DR

Mu is optimized for speed and responsiveness

Mu is designed for speed, using a streamlined architecture with 330 million parameters and training on millions of real-world examples.
It's been fine-tuned with help from Intel, AMD, and Qualcomm to work well across different devices—even older ones.
Right now, it can respond instantly to commands like "turn on night light," making everyday stuff way easier.
