Open Source Overview

PostgresML maintains three open source projects:


pgml is a PostgreSQL extension which adds SQL functions to the database where it's installed. The functions work with modern machine learning algorithms and latest open source LLMs while maintaining a stable API signature. They can be used by any application that connects to the database.

See the pgml docs for more information about pgml.


Korvus is an all-in-one, open-source RAG (Retrieval-Augmented Generation) pipeline built for Postgres. It combines LLMs, vector memory, embedding generation, reranking, summarization and custom models into a single query, maximizing performance and simplifying your search architecture.

See the Korvus docs for more information about Korvus.


PgCat is PostgreSQL connection pooler and proxy which scales PostgreSQL (and PostgresML) databases beyond a single instance

See the PgCat docs for more information about PgCat.
