At the TAAC x KDD Cup 2026, the industrial track champions utilized only a single DeepSeek web chat session—no APIs, GPT, or Claude—to design a unified Recommendation Block and optimize AUC. The competition leveraged anonymized data from Tencent's real-world business serving billions of users, exploring the Scaling Law of recommendation systems. Meta's Rui Li noted that unlike LLMs, recommendation systems lack established benchmarks, making this real-world problem exposure significant.
