PyTorch 2.15 speeds Mac MoE decoding up to 6.5×
PyTorch 2.15 brings large speedups and new capabilities to Apple silicon Macs. The release is from the PyTorch team at Hugging Face, which works on the MPS backend to make the Mac a first-class place to run and train PyTorch models. At the start of 2026, running even small models on MPS often meant working around unsupported operations, performance cliffs and unexpected memory growth. The team runs real models from the Hugging Face Hub across language, image and video, finds where MPS falls short, and fixes it upstream in PyTorch, increasingly by replacing MPSGraph with dedicated Metal...
