LlamaIndex

The RAG framework focused on data ingestion, turning any source into retrievable knowledge

What it is

A framework for retrieval-augmented generation whose core value is ingesting data of any format and source: documents, databases, APIs, knowledge graphs, then organising it into queryable indices. Its abstraction layers are more complete than most peers.

Highlights

  • Ingests documents, databases and APIs
  • Offers layers from simple vector search to graph retrieval
  • Many ready-made connectors included
  • Query engine and chat engine designed separately

How to use

Install it, load a directory and build an index in a few lines, then swap retrieval strategies to tune results.
