In an epoch-defining conversation on Machine Learning Street Talk, NVIDIA VP of Research Ming-Yu Liu presents NVIDIA Cosmos—a foundation model architecture transforming visual generation into interactive physical world simulation. By treating action as a first-class model token, unifying forward and inverse dynamics under an information bottleneck, and establishing ranking-preserved neural verification, Cosmos provides the foundational software substrate for embodied general intelligence.
