I don't know how many others here have a CoPilot+ PC but the NPU on it is basically useless. There isn't any meaningful feature I get by having that NPU. They are far too limited to ever do any meaningful local LLM inference, image processing or generation. It handles stuff like video chat background blurring, but users' PC's have been doing that for years now without an NPU.
NPUs were pushed by Microsoft, who saw the writing on the wall: AI like chatgpt will dominate the user's experience, edge computing is a huge advantage in that regard, and Apple's hardware can do it. NPUs are basically Microsoft trying to fudge their way to a llamacpp-on-Apple-Silicon experience. Obviously it failed, but they couldn't not try.
Then where is a demo application from Microsoft of a model that I can run locally where my user experience is so much better (faster?) if my computer has an NPU?
