Pinecone is a managed vector database built for AI applications. It stores and searches high-dimensional vectors (embeddings) with millisecond latency. It's the most popular vector database for RAG applications and semantic search.

Why use Pinecone over other vector databases?

Pinecone is fully managed (no infrastructure to maintain), scales automatically, and offers excellent query performance. It integrates seamlessly with LangChain, LlamaIndex, and OpenAI. Trade-off: it's more expensive than self-hosted alternatives like Chroma or Weaviate.

How much does Pinecone cost?

Pinecone offers a free tier (1 index, 100K vectors). Paid plans start at $70/month for serverless. For production workloads with millions of vectors, costs range from $70-700+/month depending on storage and query volume.

What is Pinecone serverless?

Pinecone serverless is their latest architecture that separates compute from storage, offering pay-per-use pricing. You only pay for what you use rather than provisioning dedicated pods. It's more cost-effective for variable workloads.

How do I get started with Pinecone?

Sign up at pinecone.io, create an index with your desired dimensions and metric (cosine, euclidean). Use the Python SDK to upsert vectors and query. Pinecone handles indexing, scaling, and optimization automatically.

Can Pinecone handle metadata filtering?

Yes, Pinecone supports metadata filtering during queries. Store metadata with each vector, then filter by properties (e.g., date range, category) while searching. This enables precise retrieval without post-filtering.

What embedding dimensions does Pinecone support?

Pinecone supports vectors up to 20,000 dimensions. Common sizes: 1536 (OpenAI), 768 (many open models), 384 (smaller efficient models). Choose based on your embedding model. Smaller dimensions = faster queries and lower costs.
