Elasticsearch
That said, the right answer changes materially if you already run Postgres, Elasticsearch, or MongoDB—using the database you already operate well is often the smarter purchase than adding a specialized vector system.

Pinecone
Pinecone — Choose this when you want the least operational burden from a dedicated, fully managed vector database, with strong support for dense, sparse, hybrid, and full-text retrieval patterns.

Where the models split.
Across the 1 category Elasticsearch and Pinecone both appear in, the models never break ranks: in each one, the same brand leads on ChatGPT, Claude, Gemini, and Perplexity alike.
No model runs against the grain here: each of the four ranks Pinecone ahead at least as often as not, with Gemini the most lopsided.
