Kuaishou's KDD 2026 Paper: Introducing PlatformBid, First Platform-Perspective Auto-Bidding Benchmark

机器之心 · wechat · 2026-08-04

Kuaishou, collaborating with Southeast University and NTU, introduced PlatformBid, the industry's first auto-bidding benchmark designed from a unified advertising platform's perspective, along with BidFlow, a new method based on Flow Matching. The research has been accepted by KDD 2026.

While traditional auto-bidding research focuses on individual advertisers (DSP perspective), PlatformBid incorporates platform-level constraints and introduces three evaluation settings: homogeneous, heterogeneous, and promotional competition. This accurately reflects the dynamic game theory and global efficiency of multiple advertisers in real-world scenarios.

To address the challenges of multimodal bidding distributions, the proposed BidFlow algorithm leverages Flow Matching for distribution modeling and utilizes Q-value guided distillation for efficient single-step inference. Experiments show that BidFlow achieves SOTA in most settings and has been fully deployed in Kuaishou's e-commerce advertising system, demonstrating strong offline-to-online consistency.
