I built a similarity search algorithm that beats FAISS HNSW on both speed
and recall. No graph construction, no learned indexes — phase-correlation
routing with multi-probe search. O(1) per query, scales to any dimension.Tested on the same data, same machine (RTX 4060), same queries, verified against brute-force ground truth:
VOIS Similarity Search — Patent Pending 100K vectors, 128-dim, top-10 retrieval, RTX 4060
QPS Recall
VOIS v3 (3 probes): 112,879 95.2%
VOIS v3 (4 probes): 100,426 99.5%
VOIS v3 (5 probes): 94,812 100.0%
FAISS HNSW: 41,668 92.1%
2.7x faster than HNSW with better recall
Multi-dimension scaling (seperate method, same hardware)
100K vectors, top-10, RTX 4060

256 79,349 99.99% 31,875 80.9%
512 29,750 100.0% 12,901 78.6%
768 40,274 97.9% 8,991 74.3%
500K vectors:
DIM VOIS QPS VOIS Recall HNSW QPS HNSW Recall
128 32,696 100.0% 31,139 67.3%
256 14,384 100.0% 17,109 50.9%
512 5,864 100.0% 8,700 41.8%
HNSW recall collapses at higher dimensions. VOIS is immune.
100% recall achieved at 2 probes for 512-dim and 768-dim.
