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.

Model Overview: Cosmos3-Super-Image2Video-4Step

Description

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.

  • What's different from the base model: Distilled into a fixed 4-step sampling schedule without the need for classifier-free guidance. At the recommended 50-step + CFG setting for the Image2Video model, this replaces 50 × 2 = 100 model evaluations with 4, leading up to 25× fewer diffusion-model evaluations per video (see PBR for latency estimates).
  • Quality: Ranked #1 among open-source models on the Artificial Analysis Image-to-Video leaderboard (as of 2026/07/17; see Benchmarks section).
  • Input / Output: Image(s) in → MP4 video out. Recommended 480p (832×480, 16:9); 189 frames by default.
  • Example usage and output: See Usage section.
  • Hardware: The 64B model needs a multi-GPU H100/H200 node (4–8 GPUs) or a single B200; it does not fit on a single smaller GPU. See Usage. Full model details below.

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.
