#### Windows ML Model Catalog APIs
49+
50+
These APIs enable your app or library to dynamically discover and download large AI model files from your own online model catalogs, and share them across apps on the PC—without bundling those large files directly with your app or library. [See the docs](/windows/ai/new-windows-ml/model-catalog/overview) to learn how to use these APIs!

#### Updated ONNX Runtime
3468
Updated the `onnxruntime.dll` to 1.23.1 introducing several enhancements to ONNX Runtime's Python and C++ APIs, focusing on improved device and memory information handling, synchronization stream support, and tensor copy functionality. It adds new Python bindings for device/memory types, exposes more detailed session input/output metadata, and provides a Python-accessible tensor copy API. The changes also refactor and extend the C++ API for better stream and memory info management.
