Summary
👤
Senior🎓
Top SchoolGuanghan Ning is a Member of Technical Staff at Fleet AI with 11 years of experience building and scaling ML systems, currently focused on RL environments and post-training for agentic models. He previously led Code-SFT at ByteDance Seed, bootstrapping coding capabilities and training Dense and MoE models up to 200B parameters, and co-authored the Seed-Coder open release. Earlier tech leadership at JD.COM produced a first-place PoseTrack solution and a production keypoint moderation system that cut manual review costs by 78.8%, and he holds 12 US patents. A PhD in computer vision and a strong open-source footprint — including significant contributions to the YOLO/darknet project and recent puzzle-style ARC environments — give him a rare mix of research depth and production-minded engineering. He brings consistent wins at academic challenges and product impact, with a habit of turning novel data and training recipes into measurable capability gains.

Contributions summary:Guanghan significantly contributed to the YOLO object detection project by adding and modifying core functionalities. They implemented a new demo mode enabling video input and output, integrated OpenCV for video processing and display, and updated the yolo.c and yolo_kernels.cu files for video handling. Furthermore, they included a Python script to convert annotation files to a darknet-compatible format. They also modified the class names and other parameters in the `yolo.c` file.
