WWDC25: Combine Metal 4 machine learning and graphics | Apple

Metal 4 introduces comprehensive machine learning capabilities for GPU programming, featuring MTLTensor as a new multi-dimensional data structure, MTL4MachineLearningCommandEncoder for running entire ML networks on the GPU timeline, and Shader ML for embedding neural operations directly into shaders. The framework enables seamless integration of ML workloads with graphics rendering, supporting techniques like neural material compression that achieves 50% size reduction while maintaining visual quality. New debugging tools including the ML Network Debugger provide visibility into network execution and help identify issues in ML pipelines.
