pgvector vs. Pinecone: Cost and scale for RAG systems

The comparison highlights the trade-offs between pgvector and Pinecone for Retrieval Augmented Generation (RAG) systems. pgvector is a free, self-hosted solution that integrates with PostgreSQL, making it suitable for smaller-scale applications with under 10 million vectors. Pinecone, on the other hand, is a managed service that offers superior performance for larger datasets exceeding 100 million vectors but comes with associated costs. AI

IMPACT Provides guidance on selecting vector database infrastructure based on scale and cost for AI applications.
