Pinecone is a managed service for searching collections of numerical representations of data, commonly called vector embeddings. Unlike a simple keyword lookup, this approach can retrieve material that is similar in meaning or other learned features.
A typical application creates embeddings using a model, stores them in Pinecone, and searches for related records when a user submits a question. Pinecone handles the search infrastructure; it does not, by itself, make a language model's answers accurate.
Useful starting point: applications that need managed similarity search or retrieval for a recommendation system or an AI assistant.
