## Executive Summary
MPS in PyTorch 2.15.

## Why It Matters (Strategic Analysis)
Replacing MPSGraph intermediate layers with custom Metal kernels eliminates CPU-GPU synchronization bottlenecks and memory transfer overhead during mixture-of-experts execution and single-token decode steps. This establishes Apple Silicon unified memory architectures as viable local environments for high-throughput inference and developer workflows.
