Frequently Asked Questions about LlamaIndex
What is LlamaIndex and what does it do?▾
LlamaIndex is a developer library for connecting your data to large language models by creating searchable indices and retrieval pipelines, enabling retrieval-augmented generation (RAG) and structured access to documents.
How do I integrate LlamaIndex with an LLM?▾
You typically plug in any LLM via a provider interface (cloud APIs or local models), configure an LLM client, and use LlamaIndex to generate embeddings, perform retrieval, and format prompts for model queries.
What types of data sources can I use with LlamaIndex?▾
LlamaIndex commonly supports plain text, PDFs, HTML/web pages, and structured data, and it provides connectors or ingestion utilities for common storage backends and databases to build indices from those sources.
Can I run LlamaIndex locally and keep my data private?▾
Yes — you can run LlamaIndex and the underlying components locally so data and indices stay in your environment; privacy depends on your deployment, so configure storage, network, and model hosting according to your security requirements.
How does LlamaIndex handle scaling and large document collections?▾
It uses techniques like chunking, embedding-based vector indexes, caching, and external vector databases or ANN libraries to scale; for very large collections you typically offload vectors to a dedicated vector store and tune chunking and retrieval parameters.
What are the main cost factors when using LlamaIndex?▾
The library itself is generally open-source, but costs come from LLM usage (API or compute), hosting infrastructure, storage and vector databases, and any managed services you choose to use.
Does LlamaIndex support non-English languages?▾
Yes — it can handle other languages, but quality depends primarily on the capabilities of the underlying LLM and embedding model you use, so test with your target languages and data.
How do I get started quickly with LlamaIndex?▾
A typical start is to install the package, prepare and ingest a small set of documents, build an index, configure an LLM client, and run a few queries; follow the official documentation and examples on the project site for step-by-step guides.
What common issues should I watch for when using LlamaIndex?▾
Frequent issues include token/sequence length limits, poorly tuned chunk sizes, mismatched embedding models, and retrieval precision problems — iteratively adjust chunking, embeddings, and retriever settings to improve results.
Where can I find official documentation and community support?▾
Refer to the project website (https://www.llamaindex.ai) for documentation, examples, and links to community channels and repositories where you can find guides and ask questions.
