What is a World Model?

A World Model is an internal representation that an AI agent builds to understand and predict its environment.

Core Idea

The fundamental insight behind World Models is that intelligent behavior requires:

1. Perception: Understanding the current state of the world
2. Prediction: Anticipating how actions affect the world
3. Planning: Choosing actions to achieve goals

Key Benefits

1. Sample Efficiency: Learn from fewer real-world interactions
2. Safe Exploration: Make mistakes in imagination, not reality
3. Transfer Learning: Reuse learned models across tasks
4. Interpretability: Understand what the agent has learned
