# Cosmos Predict2.5

Cosmos-Predict2.5 is NVIDIA's world foundation model for physical AI: it continues or generates video from text, an image or a clip. An action-conditioned variant predicts what a robot will see after an action, which makes it a simulator for policy work rather than a game engine.

Organization: NVIDIA. Released: September 2025. Kind: Physical AI.
