25 Aug 2026I wrote HNSW from scratch and found out I didn't need it
Benchmarking a from-scratch Python HNSW against FAISS and exact brute-force vector search on BEIR: below ~5,000 documents brute force wins by 10–18×, the query encoder dwarfs the index either way, and BM25+dense fusion (RRF) is the only statistically significant quality gain.
