How do you deliver full API parity across heterogeneous accelerators with zero additional overhead?

At PyTorch Conference North America 2026, Zesheng Zong (Huawei), PyTorch Foundation Ambassador and Accelerator Integration Working Group Co-Chair, will share key technical updates on backend integration. The community is adapting over 600,000 upstream test cases to be generic across all backends, providing a scalable path toward complete API parity. Alongside this effort, Cross-Repository CI Relay connects every PyTorch pull request directly to accelerator repositories, enabling real-time bidirectional testing, early regression detection, and a lower barrier to entry for out-of-tree hardware
