About LlamaIndex Hub
Build and debug RAG retrieval pipelines
What this site covers
LlamaIndex Hub covers retrieval-augmented generation with LlamaIndex: getting documents in, splitting them sensibly, storing the vectors somewhere that scales, and getting an answer back that can be traced to a source.
- Ingestion pipelines, document loaders, and the parsing failures that silently empty a corpus
- Chunk size, overlap, and structure-aware splitting, and what each does to retrieval
- Vector store integration, including Qdrant, and sizing an index before provisioning it
- Knowledge graph indexes and multi-hop questions that vector similarity handles badly
- Query engines, node postprocessors and rerankers, and measuring retrieval with hit rate and MRR
7 articles are published so far. New ones are announced on the RSS feed.
Where to start
If you are new to the framework, read ingestion, indexing and retrieval explained for the concepts, then the Python quickstart for working code. If a pipeline already runs and the answers are wrong, retrieval troubleshooting is organised in diagnosis order. Still choosing a stack? LlamaIndex vs LangChain compares what each project's own documentation says it optimises for.
The site also maintains one free browser-side tool, the chunking and vector store sizer, which turns corpus size, chunk size and embedding dimensions into a chunk count and an approximate index memory figure. Nothing is uploaded and there is no signup.
How these articles are produced
Articles here are researched from primary sources: vendor and project documentation, published standards and specifications, research papers and preprints, and measurements published by whoever took them. Drafts are produced with AI assistance and then edited against those cited sources before anything is published.
No article on this site is based on first-hand testing in a private lab, and nothing here should be read as a measurement report of its own. Where a number appears, it comes from a source that is named, so you can check the original instead of taking this site's word for it.
Everything is published under a single editorial byline. That byline is a publishing identity for the site, not a claim about a named individual, and it does not carry professional credentials.
Corrections
Corrections are welcome. If something here is wrong, out of date, or attributed to the wrong source, email [email protected] with the page address and what it should say. Substantive corrections are made in the article itself rather than quietly dropped.
How this site is funded
This site currently runs no affiliate links, sponsored posts, display advertising or paid placements. If that changes, the disclosure page will say so.
