Vector store selection (Pinecone, Chroma, FAISS) in Agentic AI - Cheat Sheet & Quick Revision

Recall & Review

beginner

What is a vector store in the context of AI?

A vector store is a system that saves and organizes data as vectors (lists of numbers) so that AI can quickly find similar items by comparing these vectors.

Name one key difference between Pinecone and FAISS.

Pinecone is a cloud-based managed service that handles scaling and maintenance for you, while FAISS is an open-source library you run on your own machine or server.

beginner

Why might someone choose Chroma as their vector store?

Chroma is easy to set up and use locally, supports fast similarity search, and is good for small to medium projects without needing cloud services.

intermediate

What is a common use case for FAISS?

FAISS is often used for fast similarity search in large datasets when you want full control over your data and infrastructure.

intermediate

How does Pinecone help with scaling vector search?

Pinecone automatically manages the storage and computing resources needed to handle large amounts of vector data, so you don’t have to worry about technical details.

Which vector store is a fully managed cloud service?

A Pinecone

B Chroma

C FAISS

D None of the above

Pinecone is a cloud-based managed vector store service.

Which vector store is best if you want to run everything locally without cloud dependencies?

A FAISS

B Pinecone

C Chroma

D All of the above

FAISS is designed for easy local use without cloud.

FAISS is primarily known as:

A A cloud service

B A database for text storage

C A visualization tool

D An open-source library for similarity search

FAISS is an open-source library for fast similarity search.

Which vector store automatically handles scaling and maintenance?

A FAISS

B Chroma

C Pinecone

D None

Pinecone manages scaling and maintenance automatically.

If you have a very large dataset and want full control over your infrastructure, which vector store is suitable?

A Pinecone

B FAISS

C None

D Chroma

FAISS lets you run similarity search on your own infrastructure.

Explain the main differences between Pinecone, Chroma, and FAISS as vector stores.

Think about where and how each vector store runs and what kind of projects they suit.

Describe a scenario where you would choose Pinecone over FAISS or Chroma.

Consider the benefits of cloud-managed services.
