| description.long | Faiss is a library for efficient similarity search and clustering of dense vectors. It contains algorithms that search in sets of vectors of any size, up to ones that possibly do not fit in RAM. | Vald is a cloud-native vector search platform running on Kubernetes that uses NGT for efficient nearest-neighbor search. It provides automatic indexing and backups, index replication across distributed agents, and horizontal scaling to handle billions of vectors. |
