Google Open-Sources TorchTPU for Native PyTorch on TPUs
Google has open-sourced TorchTPU as a replacement for PyTorch/XLA, enabling developers to run and debug PyTorch code natively on TPUs. The tool simplifies debugging by executing operations step-by-step before switching to torch.compile for production performance, achieving up to 52% of peak TPU compute when training Qwen 3 8B.

Google and Amazon now both offer native PyTorch backends that let code leave Nvidia GPUs.
Google just open-sourced TorchTPU that replaces PyTorch/XLA, letting developers debug TPU models step by step.
TorchTPU used up to 52% of peak TPU compute training Qwen 3 8B.
TPUs previously reached PyTorch through PyTorch/XLA, which queued operations for a compiler, so debugging differed from GPU work.
TorchTPU replaces that layer, running each operation as written for debugging, then switching to torch.compile for production speed.
