AI Agents Explained: From Simple RAG to Agentic AI Systems

AI agents go beyond basic RAG by reasoning, using tools, and executing multi-step plans. Learn agentic RAG, tool calling, memory systems, and LangGraph orchestration.

Basic RAG retrieves documents and generates answers. Agentic RAG goes further — the AI decides WHAT to retrieve, WHEN to use tools, and HOW to break complex questions into steps.

Agent Capabilities

  • Tool calling: Agents can query databases, call APIs, run code, search the web
  • Multi-step reasoning: Break complex questions into sub-tasks
  • Memory: Remember context across conversations
  • Multi-agent: Specialized agents collaborating on complex tasks
