Google releases tool to move PyTorch apps off Nvidia GPUs

Google has released a developer tool that makes it easy for PyTorch users to move their applications off Nvidia GPUs. It follows a similar move by Amazon.

Why it matters: Nvidia's moat rests largely on software lock-in, and PyTorch portability from both Google and Amazon (TorchNeuron) attacks it directly. If migration gets cheap, the custom-silicon clouds gain leverage in a market where compute supply is tight.
