World Models
Models that learn predictive representations of environments: compressing observations into latent states and modeling their dynamics to imagine futures.

Core idea
Intelligence that plans needs a simulator. A world model learns the dynamics of an environment in latent space, letting systems rehearse consequences before acting.
Why it exists
Acting in the real world is expensive and risky; systems that can simulate outcomes internally can plan, explore and learn far more safely.
Data Flow
What moves through the system
- 01Observations are encoded into latent states.
- 02A dynamics model predicts future latents under actions.
- 03The system imagines rollouts in latent space.
- 04A policy or planner selects actions using imagined futures.
Strengths
- + Sample-efficient planning
- + Safe rehearsal of consequences
- + A path toward general embodied intelligence
Limitations
- − Latent dynamics drift from reality
- − Evaluation is an open research problem
Applications
