What is LlamaIndex?

Discover how LlamaIndex can enhance your workflow

LlamaIndex provides open source libraries and a managed cloud for connecting data to LLMs. Developers use connectors to bring in files drives databases and apps then build indexes retrievers and query engines that ground model answers in private content. The hosted LlamaCloud adds credits for ingestion and queries multi user workspaces data agents observability and deployments with REST endpoints. Teams start on Free then move to Starter for small apps or Pro for heavier loads with more credits and users while enterprises get SSO VPC and custom limits. The ecosystem integrates with LangChain vector stores and major model providers so you can swap components without lock in. Typical outputs include chat over docs semantic search evaluators and agents that call tools while citing sources for trust.
