Overview
LlamaIndex (formerly GPT Index) is an open-source framework bridging large language models (LLMs) with private or domain-specific data. It enables developers to build context-aware AI apps by indexing, querying, and integrating external sources like documents, databases, APIs, and spreadsheets. Supporting popular LLMs (GPT-4, Claude, Llama 2), it enhances responses with relevant, up-to-date information. Key use cases include private knowledge base chatbots, internal document QA systems, and personalized content generators.
