SymphonyQG: Towards Symphonious Integration of Quantization and Graph for Approximate Nearest Neighbor Search

Summary: SymphonyQG tightly couples quantization and graph indices for ANN, avoids re-ranking, and aligns the graph with FastScan’s batch distances. It achieves time-accuracy at 95% recall, with 1.5-4.5x QPS gains over baselines and ≥8x faster indexing than NGT-QG. (summarized by gpt-5-nano on Feb 09 2026)
