Over a three-month period, Xie worked on the bytedance-iaas/sglang repository, focusing on deep learning model optimization and deployment. He implemented INT8 and AWQ quantization support, updating tuning scripts and documentation to enable efficient inference and broader quantization options. Xie integrated DeepGemm into the sgl-kernel, managing submodules and build systems in C++ and Python to improve performance and maintainability. He also delivered Expert Parallel Mixture of Experts support for the Qwen3 model, allowing dynamic selection between inference paths for distributed systems. His work demonstrated depth in model serving, quantization, and distributed computation, with careful attention to code quality.
