LlamaIndex

Data framework for RAG; ingest, index and query your own corpus.

LlamaIndex is a data framework for connecting large language models to private or domain-specific data, with a focus on retrieval-augmented generation (RAG). It provides data loaders, indexing structures, retrievers, and query engines to ingest documents and serve grounded answers. It is widely used for building question-answering systems and knowledge assistants over custom corpora.
