Summary

A framework focused specifically on connecting LLMs to your data — indexing, retrieval and query engines — often preferred over LangChain for RAG-heavy applications.

• 1Build a basic RAG pipeline using LlamaIndex's index and query engine abstractions.
• 2Compare LlamaIndex's RAG-focused API against a hand-rolled RAG pipeline you built earlier.
• 3Learn when LlamaIndex's higher-level abstractions save real time vs. add complexity.
