NVIDIA Cosmos™ is a world foundation model platform designed to accelerate the development of Physical AI by enabling machines to understand, simulate, and interact with the physical world across robotics, autonomous driving, and smart space environments, including industrial and factory-scale applications.
Cosmos3-Super-Image2Video-4Step is a 4-step distilled version of the base Cosmos3-Super-Image2Video model. Given an input image plus an optional text prompt, it generates a temporally coherent video.
Cosmos3-Super-Image2Video-4Step was developed by NVIDIA as a part of Cosmos3.
Cosmos3 is a collection of Omnimodal world models capable of generating dynamic, high-quality video, image, audio, and action commands from combinations of text, image, video, and action trajectory inputs. It serves as a foundational building block for a broad range of Physical AI applications and research spanning world understanding, world generation, simulation, and embodied policy learning.
This model is ready for commercial and non-commercial use.

Architecture Type: Transformer
Network Architecture: Mixture-of-Transformers (MoT)
Cosmos3 is an Omni-modal foundation model built on a Mixture-of-Transformers (MoT) architecture consisting of two complementary transformer towers: an autoregressive transformer for discrete token generation and a diffusion transformer for continuous multimodal generation. During inferen

Running it yourself
Rent a machine by the hour. Runs as it is with diffusers, on the machine, in Python.
# on your rented machine: pip install diffusers transformers accelerate ftfy
import torch
from diffusers import DiffusionPipeline
from diffusers.utils import export_to_video
pipe = DiffusionPipeline.from_pretrained("nvidia/Cosmos3-Super-Image2Video-4Step", torch_dtype=torch.bfloat16).to("cuda")
