Data framework that connects large-language models to private or enterprise data via indexing, retrieval and agent orchestration.
LlamaIndex (formerly GPT-Index) is an open-source toolkit for loading, transforming, indexing, and querying private or enterprise data with LLMs. It abstracts away boilerplate so you can build context-aware agents, chatbots, and RAG pipelines that securely reason over structured or unstructured data at scale.
