Types of AI Agents: Exploring the Spectrum of Intelligence

The Six Fundamental AI Agent Types

AI agents can be categorized based on their capabilities and decision-making sophistication:

1. Simple Reflex Agents

These agents make decisions based solely on the current percept, with no memory of past percepts. They follow simple condition-action rules.

2. Model-Based Reflex Agents

They maintain internal state to track aspects of the world not evident in the current percept, allowing for more sophisticated behavior.

3. Goal-Based Agents

These agents consider future actions and their outcomes to achieve specific goals, using search and planning algorithms.

4. Utility-Based Agents

When there are multiple possible alternatives, these agents make decisions based on which option maximizes their utility function.

5. Learning Agents

They improve their performance over time through machine learning techniques, adapting to new situations.

6. Hierarchical Agents

Complex agents that operate at multiple levels of abstraction, with different layers handling different aspects of decision-making.
