What Is an AI Agent?
An AI agent is a software-based entity designed to autonomously perceive its environment, make decisions, and take actions to achieve specific goals. Unlike traditional software that requires step-by-step programming or repeated inputs, AI agents can react to changes, adapt, and learn through feedback.
Think of an AI agent as a digital assistant that works with initiative, often operating continuously or on triggers, making them ideal for repetitive or evolving workflows.
How AI Agents Work: A Technical Breakdown
At the core, AI agents follow this decision-making loop:
- Perception – Gather data (e.g., from APIs, sensors, databases).
- Reasoning – Use logic or models to understand the situation.
- Planning – Decide what to do next based on goals and constraints.
- Action – Execute the plan, often by calling external systems or tools.
- Learning (optional) – Improve future decisions using feedback.
Many modern agents rely on Large Language Models (LLMs) like ChatGPT or Claude to power their decision-making, but AI agents are more than just LLMs.
