CPU vs GPU vs MPS: Pick a Device

Detect CUDA, Apple MPS, or fall back to CPU.

Where Math Happens

Every tensor lives on a device: the CPU, a GPU, or Apple's MPS. The device decides how fast your model trains. ⚡

The CPU Always Works

Your CPU is the safe default. It runs every PyTorch operation, just more slowly on the heavy matrix math that big networks demand.
