Microsoft Launches "Mu," New On-Device AI Model for Copilot+ PCs

Microsoft Corporation (NASDAQ:MSFT) is one of the best US tech stocks to buy now. On June 23, Microsoft officially launched a new small language model called Mu. The AI tool is designed for efficient local operation on personal computers, particularly the new Copilot+ PCs. Unlike larger AI models that rely on cloud processing, Mu operates entirely on a device’s Neural Processing Unit/NPU, which enables rapid responses while consuming less power and memory.

Mu is an efficient 330 million parameter encoder-decoder language model optimized for small-scale deployment on NPUs. Its design was carefully tuned to fit the hardware’s parallelism and memory limits, and ensure peak efficiency for operations. The model’s development used insights gained from Microsoft’s earlier Phi models and was pre-trained on hundreds of billions of high-quality educational tokens.

To enhance its performance despite having fewer parameters, Mu was fine-tuned using advanced techniques such as distillation and low-rank adaptation, and it also incorporates transformer upgrades like Dual LayerNorm, Rotary Positional Embeddings/RoPE, and Grouped-Query Attention/GQA. Initially, the Mu model will be applied to the Settings function within the Windows system, using natural language processing to convert user inputs into system commands.

Microsoft Corporation (NASDAQ:MSFT) develops and supports global software, services, devices, and solutions.
