Nvidia has released Cosmos-Transfer1, an advanced artificial intelligence model designed to enhance simulation-based training for robotic systems.
Highlights
As part of the company’s Cosmos Transfer world foundation models (WFMs), this open-source AI model enables robots to learn from highly realistic simulated environments, providing researchers and developers with a tool to refine autonomous systems before real-world deployment.
Advancements in Simulation-Based Robot Training
Simulation-based training has gained traction with generative AI, particularly in robotics. While traditional robots are primarily designed for repetitive tasks, Cosmos-Transfer1 introduces a method for training AI-driven machines through photorealistic simulations.
The model processes structured video inputs such as segmentation maps, depth maps, and LiDAR scans to generate realistic video outputs.

Features of Cosmos-Transfer1
A defining aspect of Cosmos-Transfer1 is its diffusion-based world generation approach. With seven billion parameters, the model specializes in video denoising within latent space, allowing developers to control and customize simulations with a high degree of precision. It supports multiple input formats, including:
- Canny edge detection
- Blurred RGB videos
- Segmentation masks
- Depth maps
By offering precise control over spatial locations, the model provides greater customization and versatility compared to its predecessors, making it a valuable asset for AI-driven robotic training and automation.
Adaptive Multimodal Control
One of the notable capabilities of Cosmos-Transfer1 is its adaptive multimodal control system, which enables developers to assign different weights to various visual inputs—such as depth information or object boundaries—within different areas of a scene.
This feature allows for more nuanced and realistic environment generation, improving the accuracy of simulations used in training autonomous systems.
Real-Time Simulation and Scalability
Cosmos-Transfer1 demonstrates significant scalability, achieving a 40x speedup when scaling from one to 64 GPUs.
The model is capable of generating five seconds of high-quality video in just 4.2 seconds, making real-time simulation feasible. This speed is particularly valuable for rapid testing and iteration in the development of autonomous vehicles, industrial robotics, and AI-driven automation systems.
Integration with Nvidia’s AI Ecosystem
Cosmos-Transfer1 is part of Nvidia’s broader Cosmos platform, which includes:
- Cosmos-Predict1 – A model for general-purpose world generation
- Cosmos-Reason1 – A model focused on physical common sense reasoning
This ecosystem provides developers with a comprehensive suite of AI tools to advance physical AI training and simulation-based development.
Availability and Future Prospects
Nvidia has released Cosmos-Transfer1 under the Open Model License Agreement, making it available for both academic and commercial use.
Researchers and developers can access the model through GitHub and Hugging Face, allowing for widespread adoption in robotics, automation, and AI research.
The model has been tested on Nvidia’s Blackwell and Hopper series chipsets, with inference running on Linux-based systems, ensuring compatibility with modern AI hardware.
Nvidia has hinted at a 14-billion parameter version of the model, which could further enhance simulation fidelity and expand its applications for next-generation AI-driven robotics and automation.
