AI Dev Gallery is a Microsoft tool that helps Windows developers add AI capabilities to their apps. It provides over 25 interactive samples powered by local AI models including Whisper for speech recognition, Stable Diffusion for image generation, and Phi3/Mistral language models. The gallery lets developers browse and download models from Hugging Face and GitHub, view the C# source code, and export standalone Visual Studio projects. It leverages ONNX Runtime with DirectML and NPU hardware acceleration for running models locally.
