LlamaIndex

LlamaIndex (formerly GPT Index) connects LLMs to your data. 2025 introduces Workflows, an event-driven way to build complex RAG pipelines.

When to Use

  • RAG (Retrieval Augmented Generation): Indexing PDFs, Docs, SQL to chat with them.
  • Structured Data: Querying SQL/Pandas with natural language (NLSQL).
  • Agents: Building research agents that browse the web and summarize.

Core Concepts

Workflows

Event-driven architecture for agents. Replace DAGs with event listeners (@step).

Query Engine

High-level API (index.as_query_engine()) to ask questions.
