LlamaIndex

LlamaIndex is a high-level framework for building retrieval-augmented generation (RAG) and agentic applications with large language models (LLMs) in Python and TypeScript.

It helps you ingest and parse data from many sources, build indices, retrieve relevant context, and synthesize answers. LlamaIndex integrates with many hosted LLM APIs and also supports local models, for example via Ollama.
