官方常见问题

What is LlamaIndex?

LlamaIndex is an AI document-intelligence company founded in 2023 and based in San Francisco. It builds LlamaParse, an agentic OCR platform that converts complex documents — PDFs with messy tables, charts, images and handwriting — into clean, structured, LLM-ready data, and it maintains the open-source LlamaIndex framework for building context-aware AI agents.

Is LlamaIndex the same thing as LlamaParse?

They are related but not the same. LlamaIndex is the company and also the name of its open-source Python and TypeScript framework for building AI agents over your data. LlamaParse is the company's commercial agentic OCR product for parsing and extracting structured data from complex documents. You can use either on its own, or use LlamaParse as the parsing layer inside a LlamaIndex pipeline.

Is LlamaIndex better than LangChain?

They solve overlapping but different problems. LlamaIndex is built around ingesting, parsing, indexing and retrieving your data so an LLM can reason over it accurately, with document understanding as its centre of gravity. LangChain is built around orchestrating chains and agents across tools and models. Teams whose hardest problem is getting messy documents into a model reliably tend to choose Ll

Is LlamaIndex free to use?

The open-source LlamaIndex framework is free under the MIT licence and always will be. LlamaParse has a free tier that includes 10,000 credits per month, roughly 1,000 pages of basic parsing, with no credit card required. Paid plans start at $50 per month.

How much does LlamaParse cost?

LlamaParse has four plans. Free is $0 per month and includes 10,000 credits. Starter is $50 per month for 40,000 credits. Pro is $500 per month for 400,000 credits with priority support. Enterprise is custom-priced with volume discounts, 5x higher rate limits, SSO and flexible deployment. Credits are priced at 1,000 credits for $1.25, and basic parsing starts at 1 credit per page.

How do I install the LlamaIndex framework?

Install the Python package with pip install llama-index, or the TypeScript package with npm install llamaindex. The source lives at github.com/run-llama/llama_index and full documentation for both languages is at developers.llamaindex.ai.
