AI & embeddings

Vector databases enable efficient storage and retrieval of vector data, which is an essential component in building AI applications that leverage Large Language Models (LLMs) such as OpenAI.

Neon supports the pgvector open-source extension, which enables Postgres as a vector database for storing and querying vector embeddings. By enabling Postgres as a vector database, you can keep your data in the open source database that you know and trust. There's no need for data migration or a proprietary vector storage solution.

To get started, see The pgvector extension.
