LlamaIndex: Connecting Data to LLMs
The data framework for LLM applications that connects private data sources to large language models.
LLMs are only as good as the data they have access to. LlamaIndex (formerly GPT Index) is the premier data framework designed specifically to bridge the gap between your custom data—databases, APIs, PDFs, Notion pages—and the reasoning engine of an LLM.
Data Ingestion and Indexing
LlamaIndex provides hundreds of "data connectors" that ingest information from almost any source. It doesn't just dump text into a model; it intelligently structures that data into optimized "indices"—like vector stores or graph structures—that allow the LLM to retrieve precise, relevant context for any given query.
Advanced Query Engines
Whether you are building a semantic search tool, a question-answering chatbot, or a document summary engine, LlamaIndex handles the heavy lifting of document orchestration, ensuring your RAG system is both accurate and contextually aware.
