The Tencent Ad Algorithm Competition (TAAC) in collaboration with KDD Cup concluded with an $885,000 prize pool. The industrial track champion team "Sunlight Surface" completed their entire workflow using only the DeepSeek web interface. The article details the QueryFormer solution from the industrial champions (focusing on Query quality over history length) and the CRAFT solution from the academic champions (addressing information transport in deep networks). Additionally, Original Breakthrough Award teams introduced TopoMask (controlled communication in a unified framework) and CosFormer (co-expansion of information and model width). The piece argues that the future of recommendation systems lies in more efficient information organization.
