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-Text2Image-4Step

Description

Cosmos3-Super-Text2Image-4Step is a 4-step distilled version of the base Cosmos3-Super-Text2Image model. Given a text prompt, it generates a high-fidelity image.

• 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 Text2Image model, this replaces 50 × 2 = 100 model evaluations with 4, leading up to 25× fewer diffusion-model evaluations per image (see PBR for latency estimates).
• Quality: At just 4 steps, ranks #2 among open-source models on the Artificial Analysis Text-to-Image leaderboard, within one place of the full-step Cosmos3-Super-Text2Image (as of 2026/07/17; see Benchmarks section).
• Input / Output: Text prompt in → PNG image out. Supports various aspect ratios and resolutions.
• 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-Text2Image-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.
