About

Mu is a 330-million-parameter encoder–decoder language model designed to power the agent in Windows settings by mapping natural-language queries to Settings function calls, running fully on-device via NPUs at over 100 tokens per second while maintaining high accuracy. Drawing on Phi Silica optimizations, Mu’s encoder–decoder architecture reuses a fixed-length latent representation to cut computation and memory overhead, yielding 47 percent lower first-token latency and 4.7× higher decoding speed on Qualcomm Hexagon NPUs compared to similar decoder-only models. Hardware-aware tuning, including a 2/3–1/3 encoder–decoder parameter split, weight sharing between input and output embeddings, Dual LayerNorm, rotary positional embeddings, and grouped-query attention, enables fast inference at over 200 tokens per second on devices like Surface Laptop 7 and sub-500 ms response times for settings queries.

Pros & Cons from Real Users

Pros

  • Copilot is surprisingly brilliant! It's not just a virtual assistant—it’s a true conversational partner. It blends intelligence, wit, and a touch of personality that makes every exchange enjoyable and stimulating. It helped me find ideas, solutions, and even light-hearted moments when I needed them most. I never imagined interacting with an AI this empathetic and sharp. Highly recommended—5 stars without hesitation!
  • I have been using Microsoft Copilot since the implementation of month in our organization. I have found this an amazing tool for summarizing long emails, writing professional emails, my research work & what not. I have been using it almost each and everyday to enhance my productivity. Also its amazing how its integration with approximately all the other Microsoft applications offers amazing functionality.

Cons

  • Intuitive and quick responses Friendly and engaging personality Great support for brainstorming and creative projects Always ready with facts, ideas, and humor
  • Only con is during my research work which occurs very often it sometimes generated false information from the web, i got to know this after a long time when i got suspicious & cross checked it.
