AI Agents vs Bots: What Is the Difference?

A bot follows a fixed script to automate a narrow, predefined task; an AI agent pursues a goal, choosing actions and adapting as it goes. A bot does the same thing every time; an agent decides. The practical consequence is accountability: because an agent exercises judgment, it needs identity, authority and a record in a way a deterministic bot never did.

Automation vs agency

The line is judgment. A bot executes a path someone wrote; an agent selects a path toward an outcome, which means its action is not fully predictable from its code. That is why agents raise questions bots never did — who authorised this, who is responsible — and why the accountability layer exists for agents and not for scripts.

Questions

Is a chatbot an agent?

Only if it pursues goals and takes actions on its own judgment. A scripted chatbot that answers from a decision tree is a bot; one that plans, calls tools and adapts is an agent.

Why does the distinction matter for infrastructure?

Because agency needs governance. A deterministic bot can be trusted by inspection; an agent that decides needs verifiable authority and an audit trail.
