Run custom AI models locally on any Windows device Windows ML is the unified and high-performance local AI inferencing framework for Windows that lets you run your own custom or open-source models on any Windows device. Build once, and scale across GPUs, NPUs, and CPUs with built-in hardware acceleration from AMD, Intel, NVIDIA, and Qualcomm. Reduce your app size by using the shared system-copy of runtime dependencies, and improve predictability by using the Windows-maintained version of runtime dependencies.
