AI / LlamaIndex Interview Questions
What is LlamaIndex?
LlamaIndex is an open-source data framework in Python (and TypeScript) built for connecting large language models to your own data, most commonly to power retrieval-augmented generation (RAG) applications.
It handles the parts of a RAG pipeline that are easy to get wrong by hand: loading data from files, APIs, or databases, splitting that data into chunks called Nodes, embedding those chunks, storing them in a vector store, and retrieving the right ones at query time to feed into an LLM prompt.
Originally released as GPT Index by Jerry Liu, it was renamed LlamaIndex as its scope grew beyond simple indexing into agents, workflows, and structured data querying, while still keeping data ingestion and retrieval as its core strength.
