亮出“中国最强AI芯片”还不够，平头哥又甩出一手开源

TL;DR - Alibaba’s T-Head expanded the open-source T-Head SAIL software stack for its Zhenwu AI chips, aiming to reduce model-porting costs and let developers optimize workloads directly. The CUDA-like ecosystem is critical to making China’s AI hardware practical across existing frameworks, models, and production systems.

• Newly opened components include PyTorch-for-sail, Sailify, Triton-for-sail, DeepGEMM-for-sail, and FlashAttention-for-sail, covering framework integration, code migration, custom operators, and acceleration.
• SAIL connects frameworks such as PyTorch to Zhenwu hardware and supports familiar C++, Triton, and TileLang development workflows.
• T-Head reports that Zhenwu chips serve more than 650 customers across over 20 industries; Xiaopeng, Ant Group, and Xiaohongshu are using SAIL for training, inference, migration, and optimization.
• Planned releases include TensorFlow and JAX support, inference and communication components, and additional debugging tools, while upstream contributions should reduce maintenance overhead and accelerate support for new models.
