NVIDIA Researcher Explains Cosmos: A World Foundation Model Is a Foundation Model of World Models

A member of NVIDIA's Cosmos team explains the concept of "world foundation model," a term coined by Jensen Huang that combines two ideas: world models and foundation models.
- World models: used broadly to mean models capturing the world knowledge a task requires—objects, environments, and physical behavior. Different tasks need different knowledge, so different world models are built, each trained on purpose-suited data.
- Why unify them: all these models describe aspects of the same physical world, making it possible to pool diverse training data into a single model that learns shared physical knowledge and adapts to many tasks and environments.
- Why it matters: in the era of physical AI, robots and autonomous systems must anticipate consequences of actions, evaluate possible futures, and make better decisions in complex, changing environments—that is the goal of Cosmos.
