Xusheng Chen's Homepage

I am Xusheng Chen. At Tencent, I lead a team building the inference infrastructure behind the R&D of the Hunyuan (HY) large language models. Broadly, my team owns inference across the model R&D lifecycle, with ongoing threads in model–infra co-design, high-precision and deterministic batch inference, and train–inference consistency and acceleration for RL rollout.

Before Tencent, I was at Huawei Cloud, where I led the team incubating XDeepServe, Huawei Cloud’s Model-as-a-Service (MaaS) platform running on the CloudMatrix SuperPod.

I received my Ph.D. from the University of Hong Kong, supervised by Dr. Heming Cui. My doctoral research was in distributed systems — consensus protocols, fault-tolerance systems, and distributed transaction processing, often built on datacenter networking hardware such as RDMA. My early work also explored systems for accelerating the training and inference of Transformer models.

I received my Bachelor of Engineering degree from the University of Hong Kong with first class honour, and enjoyed a wonderful exchange program at UCSD during my undergraduate study.

I am from Shenyang, a beautiful city in northeast China. See my Google Scholar for a full list of publications.
