FAQ about LlamaIndex

QWhat is LlamaIndex? What is it mainly used for?

LlamaIndex is an open-source framework for building applications based on large language models. It acts as a bridge between LLMs and external data sources, leveraging data indexing, retrieval-augmented generation, and agent workflows to help developers build efficient AI applications using private or domain-specific data, such as intelligent Q&A and automated document processing.

QWho is LlamaIndex suitable for?

LlamaIndex is aimed at developers and enterprises who need to build high-performance, reasoning AI applications using their own data. It is especially suitable for industries such as finance, insurance, manufacturing, healthcare, and engineering that have substantial document processing and knowledge management needs.

QIs there a cost to use LlamaIndex? Is there a free trial?

The core framework of LlamaIndex is open-source. Its official hosted service, LlamaCloud, offers 10,000 free credits for new sign-ups to experience cloud-based document parsing, retrieval, and other augmented services. For enterprise features and quotas, please refer to the official pricing.

QHow does LlamaIndex handle my private data? Is it secure?

The core design of LlamaIndex is to help you connect and index private data locally or in a controllable environment. With the framework, data processing and index construction can be done on your own infrastructure. When using the cloud service LlamaCloud, data security and privacy follow the terms of service; enterprises should evaluate carefully.

QHow does LlamaIndex differ from a simple chatbot?

LlamaIndex goes beyond basic dialogue. It focuses on automating complex tasks through agents and workflows. It can understand document context, perform multi-step reasoning, call tools, and maintain task state, suitable for professional scenarios such as contract analysis and compliance reviews that require logical reasoning and process automation.

QAs a developer, how can I quickly get started with LlamaIndex?

Developers can quickly start with the official Python/TypeScript libraries. The platform provides thorough documentation, quick-start guides, rich sample code, and hundreds of ready-to-use components in LlamaHub. It is recommended to start by building a simple RAG QA application to experience it.
