FAQ
LlamaIndex is an open-source data orchestration framework designed to help developers build large language model (LLM) applications. It specializes in Retrieval-Augmented Generation (RAG), enabling LLMs to access and use private, domain-specific, or up-to-date data for more accurate and context-aware responses.
RAG is a technique that combines information retrieval with language generation. LlamaIndex retrieves relevant data from your documents or databases and uses it to ground the LLM’s responses, reducing hallucinations and improving accuracy.
LlamaIndex supports unstructured data like text files, PDFs, Notion, Slack, and web pages; structured data such as SQL databases and CSV files; complex documents including PDFs with tables, charts, and images; and multiple data sources, allowing for combining and routing queries across different formats and locations.
LlamaIndex can ingest unstructured documents, parse them (using tools like LlamaParse), and index the content for semantic search and summarization. It supports advanced features like multi-document queries and routing across heterogeneous data sources.
Yes. LlamaIndex can perform text-to-SQL and text-to-Pandas operations, allowing you to ask natural language questions over SQL databases and CSV files.
The main use cases for LlamaIndex include building document agents for customer support such as FAQs, manuals, and policies; creating chatbots and query engines for domain-specific knowledge; developing AI agents with web data retrieval capabilities; and supporting multi-step, temporal, and multi-document queries.
LlamaIndex can generate a query plan to answer questions that require information from multiple documents. It can break down complex queries into sub-questions, retrieve answers from different sources, and synthesize the final response.
Yes. LlamaIndex can route queries to the most appropriate data source based on the question, using a router query engine that selects the best sub-index or tool for the task.
The workflow for building a LlamaIndex application involves several steps: first, ingest data from various sources; second, process and chunk the data; third, index the data using embedding models; fourth, retrieve relevant information via semantic search; and finally, generate responses using an LLM, grounded in the retrieved context.
LlamaIndex is open-source and free to use. However, some advanced features or integrations (like LlamaCloud or LlamaParse) may have associated costs or require credits.
LlamaIndex integrates seamlessly with popular frameworks like LangChain, Flask, Docker, and ChatGPT, making it easy to build and deploy AI agents and applications.
Key features for production AI systems include data connectors for various sources such as APIs, PDFs, Word documents, SQL databases, and web pages; advanced indexing and retrieval techniques; support for real-time web scraping and structured data extraction; and tools for building AI agents with data retrieval capabilities.
