Cambricon's W. Li on Device-agnostic PyTorch: Unified Infrastructure for Multi-Backend Ecosystems

Cambricon engineer W. Li published a video talk titled "Towards Device-agnostic PyTorch: Building Unified Infrastructure for a Multi-Backend Ecosystem" on the official PyTorch YouTube channel on September 24, 2026. The resource addresses the infrastructure challenges arising as AI computing evolves from single chips to platforms and ecosystems.

According to the publisher's description, Cambricon proposes an "upstream-first" philosophy based on its decade-long experience in full-stack co-optimization. The talk aims to demonstrate how to harden PyTorch's device-agnostic foundation to support every PrivateUse1 backend. The core goal is achieving seamless cross-device experiences by fixing issues upstream, thereby unlocking broader device reach and richer backend-native capabilities.
