World models
Models that learn an internal simulation of an environment so an agent can predict consequences before acting.
What World models is
A world model predicts how a scene or system will evolve, enabling planning by imagination rather than trial and error in the real world.
How it works
Video and interaction data train a predictive model of dynamics; a policy is then trained inside that learned simulator and transferred to reality.
Why it matters
It is a leading research direction for sample-efficient robotics and for generative environments, though production use remains limited.
Common uses
- →Robot policy training
