World Foundation Models

Build on Cosmos 3

The frontier omni-model family for physical AI with native reasoning, world simulation, and action generation. Built on Mixture-of-Transformers for leaderboard-topping accuracy.

Reason and Analyze

Use as a vision language model (VLM) to reason over objects, interactions, and intent across complex real-world scenarios. 

Features real-time alerts and dense captioning across quality inspection, public safety, traffic monitoring, logistics, and autonomous driving.

Build Specialized Models

Accelerate robot policy learning with NVIDIA Cosmos™ 3 as the backbone for world action models (WAMs).

Post-train the generalized world foundation model on specialized camera and embodiment data. The policy model adapts pre-learned actions to specific tasks, domains, and behaviors at scale.

Simulate Worlds

Run as a controllable, physics-grounded world simulator to predict single-view or multi-view world states, evaluate outcomes in a closed loop, and converge on the right behavior. 

Scale the loop across environments, tasks, and conditions to continuously improve without real-world risk.

Generate Data

Generate infinite plausible futures from text, image, video, ambient sound, and action input. 

Use video generation as imagination to train physical AI without being constrained by what's been physically captured.

Frequently Asked Questions

NVIDIA Cosmos is an open platform for building world models, with frontier world foundation models, open datasets, training and optimization frameworks, and data processing and generation blueprints across the development lifecycle.

Cosmos 3 is built on Mixture of Transformers architecture. Reasoning and generator modules use different transformers for efficient generation and performance. The model therefore reasons first and then generates, resulting in leading physics accuracy across capabilities. Learn more about the architecture here.

Cosmos WFMs are available under the OpenMDW1.1 license from Linux Foundation.

Cosmos 3 is openly available with post-training scripts on GitHub for each modality and module. In addition, NVIDIA TAO 7 provides a suite of agent skills and tools for fine-tuning vision AI models, including Cosmos 3, with coding agents and natural language prompts.

Yes, you can leverage Cosmos to build from scratch with your preferred foundation model or model architecture. You can start by using Cosmos Curator for video data preprocessing. Then compress and decode your data with Cosmos tokenizer. Once you have processed the data, you can train or fine-tune your model. 

Using NVIDIA NIM™ microservices, you can easily integrate your physical AI models into your applications across cloud, data centers, and workstations.

You can also use NVIDIA DGX Cloud to train AI models and deploy them at scale anywhere.

Cosmos 3 is an omni-model it can generate across text, image, video, sound and action. While Cosmos 2.5 and Cosmos 2 kept perception and generation as separate models and modalities were limited to text, image and video.

Omniverse creates realistic 3D simulations of real-world tasks by using different generative APIs, SDKs, and NVIDIA RTX rendering technology.

Developers can input Omniverse simulations as instructional videos into Cosmos Transfer models to generate controllable, photorealistic synthetic data.

Together, Omniverse provides the simulation environment before and after training, while Cosmos provides the foundation models for generating video data and training physical AI models.
