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.
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.
Features that scale with your needs
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
Run simple SQL commands to generate vectors and run LLM models.
Support for 20+ embedding models and LLMs
Access Open AI, Cohere, Jina AI, and other open-source models.
Automatically generate vector and LLM columns
Create new vector or LLM columns based on your existing data.
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.
