About LlamaIndex
What is LlamaIndex?
LlamaIndex is a leading open-source data framework designed to connect custom data sources to large language models (LLMs). It provides powerful tools for indexing, retrieving, and augmenting data to build context-aware AI applications, including RAG (Retrieval-Augmented Generation) systems.
The problem it solves
Without LlamaIndex, developers face difficulties integrating their own data (such as databases, files, and APIs) with LLMs, making it complex to build intelligent applications that use live data. LlamaIndex simplifies this process by providing ready-made connectors for over 100 data sources, and advanced indexing and retrieval tools.
Key features
- Data connectors for over 100 sources (PDFs, SQL, APIs, Notion, Slack, etc.).
- Advanced indexing and retrieval for building RAG pipelines.
- Support for multiple LLMs (OpenAI, Anthropic, Hugging Face, etc.).
- Workflow orchestration and agentic AI capabilities.
- Comprehensive tutorials, detailed documentation, and strong community support.
