What is an AI Agent? โ€” Beyond Chatbots

Chatbot vs agent

A chatbot answers one question at a time based on what you type. An agent pursues a goal across multiple steps โ€” deciding what to do next, using tools, and adjusting its plan based on results โ€” with far less human direction per step.

The three defining traits of an agent

1. Autonomy โ€” it decides its own next action. 2. Tool use โ€” it can act in the world (search, calculate, call APIs), not just generate text. 3. Iteration โ€” it observes results and adjusts, rather than producing one final answer.

Where agents genuinely help vs. hype

Agents shine at multi-step research, data gathering across sources, and repetitive workflows with clear success criteria. They struggle with ambiguous goals, tasks needing real-world judgment, and anything high-stakes without human review.

Key Takeaways

  • Agents pursue multi-step goals autonomously, unlike single-turn chatbots.
  • The three traits are autonomy, tool use, and iterative adjustment.
  • Agents excel at research and repetitive workflows with clear success criteria.
  • Ambiguous or high-stakes tasks still need human oversight.
