Zx

Zixuan Zhang contributed to several PaddlePaddle projects by developing backend and performance features across Paddle, PaddleX, PaddleOCR, and PaddleFormers repositories. He implemented vectorization support in the CINN backend, optimizing for-loop execution using C++ and CUDA to leverage hardware vector instructions. In PaddleX, he enabled CINN-based static inference for DCU devices, improving throughput for deep learning workloads. For PaddleOCR, he added runtime configurability for CINN compiler flags using Python, enhancing user control over inference optimization. Additionally, he delivered supervised fine-tuning support for DeepSeekV3 on XPU hardware, focusing on configuration management and efficient model training workflows. His work demonstrated technical depth.
