In detail

LlamaIndex is a data framework for building large language model applications that work with external data. It helps developers create specialized chat tools and assistants that draw on information beyond a model’s built-in knowledge, connecting conversational experiences with relevant source material.

It is suited to developers and teams building assistants around their own data. Rather than serving as a ready-made chatbot, LlamaIndex provides a foundation for applications that help users ask questions, explore information, and get responses informed by external content.
