LlamaIndex Python Framework
LlamaIndex is an open-source Python framework for building LLM-powered applications including agents, RAG pipelines, and custom workflows. It provides data connectors for ingesting data from various sources such as APIs, PDFs, databases, and more. The framework offers high-level abstractions like query engines, chat engines, and agent classes (FunctionAgent, ReActAgent, CodeActAgent), as well as lower-level APIs for advanced customization.
