Which to choose?
Pinecone for teams wanting a managed vector DB without managing infrastructure. Weaviate for those wanting open source, hybrid search, and self-hosting for GDPR.
Our verdict
For enterprise RAG systems in SMEs, both are excellent. Pinecone is the 'plug and play' choice: create an index, upload vectors, and it works. Weaviate is the choice for those wanting more control, hybrid search (useful for local-language documents), and the option to keep data on-premise for GDPR compliance.
