About

I am Yiyang Chen (陈逸洋), also known online as Monoxide Chen. I am an Agent Harness Engineer working on the agent harness for Kimi at Moonshot AI. Before that, I was an Agent Algorithm Engineer at RealAI, where I built general-purpose agent workers adaptable to vertical domains, drawing heavily on my previous research in more specific fields.

Previously, I received my bachelor's degree in Computer Science from Tsinghua University. I was a Research Assistant at National University of Singapore, advised by Prof. Angela Yao on 3D Segmentation and VLMs from July, 2024 to June, 2025. Prior to that, I worked with Prof. Tat-Seng Chua in the field of image-text retrieval from June, 2022 to August, 2022. I also conducted research on retrieval at THUIR with Prof. Yiqun Liu during my undergraduate studies.
