AI & Embeddings
Build AI applications with Neon Postgres as your vector database
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).
Neon supports the pgvector open-source extension, which enables Postgres as a vector database for storing and querying embeddings. This means you can leverage the open-source database that you trust as your vector store and forget about migrating data or adding a third-party vector storage solution.
Neon's AI Starter Kit provides resources, starter apps, and examples to help get you started.
