Google and AWS make PyTorch native on their chips and loosen CUDA’s grip

On October 22, 2026, at PyTorch Conference North America, Google open-sourced TorchTPU for its TPUs and AWS launched TorchNeuron in public beta for its Trainium chips, two native PyTorch backends that avoid JAX or CUDA dependencies. Getting started is easy, but peak performance still needs chip-specific tuning, with a 30 to 40% penalty for TorchTPU’s default approach.
