Pinecone
Managed retrieval stacks where low-latency similarity search is on the hot path.
Use it when
Retrieval quality and latency matter enough that a managed vector layer is simpler than building one into the app stack.
Pricing and lock-in notes
Pricing: Usage-based vector infrastructure with index and capacity choices.
Lock-in: Medium to high because retrieval design, indexing choices, and query paths become provider-shaped.
Managed vector database for embeddings, indexing, and low-latency similarity search.
