What Is Agentic AI? Beginner’s Guide

TL;DR

  • Agentic AI focuses on achieving a goal rather than just answering questions.
  • Agents autonomously select tools, perform actions, and check results to complete tasks.
  • A good agent typically handles one job with approved tools and clear limits.
  • The key difference between regular AI and agentic AI is action and autonomy.
  • Agentic systems require surrounding machinery like instructions, tools, memory, and guardrails to function reliably.
  • The agentic loop involves: Goal Observe Decide Act Check Repeat or stop.
  • Agentic systems are distinct from workflows, which follow pre-mapped steps.
  • Building agentic systems requires reliable machinery for retrieval, memory, permissions, retries, monitoring, and human approval.
