Lantern is the real deal; They helped fixed our Postgres setup and we were able to scale to 10M+ vectors with <50ms query times.

Vector search and BM25 in Postgres

Get advanced search functionality inside Postgres with extensions -- no separate vector database or search engine required.

Vector search with pgvector

Search over sparse and dense vectors, with support for binary, scalar, and product compression. Scale seamlessly to millions and beyond with serverless indexing.

Text search with BM25

Use the BM25 ranking algorithm - the industry standard used in ElasticSearch - for more relevant text search results, surpassing the default full text search capabilities in Postgres.

Hybrid search

Combine vector search and BM25 text search using RRF or other reranking algorithms for better results.

Scale to millions with serverless indexing

Scale effortlessly without compromising database performance by offloading vector index creation to a separate machine from your main database. - Infinite scalability: Use as many or as little resources as you'd like, depending on your needs - Performance: Build or update indexes without slowing down your database - Seamless integration: Simply add external=true to vector index creation

Embedding generation and LLM integrations

Simplify AI workflows by generating embeddings and running LLMs directly within your database. - Generate vectors and run LLMs in Postgres - Support for 20+ embedding models and LLMs - Automatically generate vector and LLM columns

Easy to use — just use SQL or your favorite ORM

No need to learn a new API or framework. Just use SQL or leverage our integrations with your favorite ORMs.
