VectorLink is not just a vector database, but a vector embedding management suite. It includes utilities to vectorise text, to index vectors, to create field and composite indexing on structured content and to perform entity resolution / record matching.
VectorLink's vector indexing is based on HNSW but improves the algorithm with parallel construction and uses circulant graphs to increase recall. Recall in the .90s is possible for millions of vectors.
The suite also contains tools for LLM Classifier Bootstrapping.
