Google open-sources TorchTPU to challenge Nvidia's dominance in AI development

Google announced TorchTPU, an open-source PyTorch backend that allows developers to run PyTorch applications natively on Google's Cloud TPUs with minimal code changes. The move, announced at the PyTorch Conference on October 20, 2026, follows Amazon's similar effort and aims to reduce developers' reliance on Nvidia's AI hardware and software ecosystem.
