Current obstacles

Sim-to-real transferModels trained in simulation struggle with real-world differences. Domain randomization and real data help but add cost.
Long-horizon planningPredicting many steps ahead compounds errors. Systems need planning layers above the model for long tasks.

Physics limits

Video prediction horizonPredicted frames accumulate error. Long-term predictions diverge from physics, limiting planning to seconds rather than minutes.

How it works

3 parts

Multimodal

Text, image, video, sound and action understanding

A single model processes all modalities simultaneously. Robots can reason across sensor inputs and predict the effects of actions.

Physics learning

Video prediction as physics

Trained as a video prediction model. By predicting what happens next, it learns implicit physics: gravity, collisions, friction, object persistence.

Coalition model

Built with industry partners

Open model built by Runway, Black Forest Labs, Skild AI and NVIDIA. Coalition reduces NVIDIA's costs and speeds adoption across robotics and automotive.

About NVIDIA

The team behind Cosmos 3

NVIDIA

AI GPUs, rack systems, CUDA, networking

NVIDIA designs the GPUs, networking and software behind most AI training and inference. Its CUDA software made GPUs the default for AI. In October 2025 it became the first company worth $5 trillion.

Vera Rubin in production in 2026; cloud partners get it from the second half of the year.
Licensed Groq's inference technology and hired its leaders for about $20B (Dec 2025).
Plans to invest up to $100B in OpenAI, tied to at least 10 GW of NVIDIA systems (Sep 2025).
