PostgresML is an extension of the PostgreSQL ecosystem that allows the training, fine-tuning, and use of various machine learning and large language models within the database. This extension turns PostgreSQL into a complete MLOps platform, supporting various natural language processing tasks and expanding Postgres's capabilities as a vector database.
The extension complements pgvector, another foundational extension for apps wishing to use Postgres as a vector database for AI use cases. With pgvector, applications can easily store and work with embeddings generated by large language models (LLMs). PostgresML takes it further by enabling the training and execution of models within the database.
