Abstract: Physical AI needs to be trained digitally first. It needs a digital twin of
itself, the policy model, and a digital twin of the world, the world model. In
this paper, we present the Cosmos World Foundation Model Platform to help
developers build customized world models for their Physical AI setups. We
position a world foundation model as a general-purpose world model that can be
fine-tuned into customized world models for downstream applications. Our
platform covers a video curation pipeline, pre-trained world foundation models,
examples of post-training of pre-trained world foundation models, and video
tokenizers. To help Physical AI builders solve the most critical problems of
our society, we make our platform open-source and our models open-weight with
permissive licenses available via https://github.com/NVIDIA/Cosmos.
