pgvector

Open-source vector similarity search for Postgres

[pgvector @pgvector]

pgvector 0.8.0 is now available with improved filtering and performance 🔥

[pgvector @pgvector]

pgvector 0.7.1 is now available with improved performance for on-disk HNSW index builds (thanks to findings from Tomas Vondra) 🔥

[pgvector @pgvector]

pgvector 0.7.0 will support indexing vectors at half precision with both HNSW and IVFFlat 🔥

[pgvector @pgvector]

pgvector now uses intrinsics + CPU dispatching for key float16 operations, providing much better halfvec performance on x86-64 than before 🔥

[Supabase @supabase]

Hybrid search combines full text and semantic search for more relevant results
