## Definition
An Intelligent Agent is an autonomous entity that perceives its environment through inputs, makes rational decisions based on goals, and executes actions using tools to achieve outcomes.

## Architectural Mechanics & Deep Dive
An intelligent agent is an autonomous entity that observes its environment through inputs and acts upon it using tools to achieve specific goals. An intelligent agent maintains internal state, plans its steps, gathers context, and self-corrects based on environmental feedback. Powered by reasoning models, intelligent agents automate complex, multi-step digital workflows that require continuous adaptation.

## Industry Applications & Real-World Use Cases
Autonomous system setups, game-playing entities, and RPA loops.

## Frequently Asked Questions

### What constitutes rationality in an intelligent agent?
Choosing actions that maximize the expected value of the performance goal based on available information.

### What is the PEAS framework for intelligent agents?
PEAS stands for Performance metric, Environment, Actuators, and Sensors, used to define agent parameters.
