Google open-sourced TorchTPU on October 20, a day after Amazon released TorchNeuron on October 19. Both let PyTorch apps move to TPUs and Trainium chips with a configuration change and no rewrite. PyTorch, built by Meta in 2016 and handed to the Linux Foundation in 2022, is used by about 85% of AI apps, and many of its features were built around Nvidia hardware. Amazon is going further, submitting code to PyTorch itself to decouple features from Nvidia chips. Developers get a real choice — but nobody has to move.
Hook: Google and Amazon just made the same move within a day of each other — and it targets Nvidia where it hurts.
Context: Google open-sourced TorchTPU on October 20, a day after Amazon shipped TorchNeuron on October 19; both port PyTorch apps to TPUs and Trainium with a configuration change and no rewrite.
Stakes: PyTorch, used by about 85% of AI apps, grew up around Nvidia hardware — that software default is Nvidia’s moat, and both clouds are now attacking it.
Payoff: Developers finally get a real choice of hardware. But nobody has to move — watch whether apps actually leave Nvidia.
