# What is an AI Agent?

An **AI agent** is a dynamic system that leverages a **large language model (LLM)** as its core reasoning engine. It is designed to interact with its environment, process inputs, make informed decisions, and execute actions to achieve specific objectives.

These agents are more than just chatbots—they blend language understanding, contextual reasoning, memory, and sometimes tool use to handle complex tasks, automate workflows, and assist users in real time.

To improve efficiency, reduce computational costs, and enhance decision-making accuracy, agents can be equipped with **structured prompts** and **external knowledge bases**.
