How It Works

Diagram showing the application and Omniverse Cloud using USD framework

Cosmos WFMs accelerate physical AI development, helping developers augment datasets and post-train downstream world models for robots and autonomous vehicles.

Cosmos Predict generates next frames based on input to build datasets predicting various edge cases and serves as the foundation for all world models.

Cosmos Reason acts as a critic, using chain-of-thought reasoning to evaluate synthetic visuals and reward outcomes. It can also generate captions to speed up data curation.

Cosmos Transfer amplifies structured video across various environments and lighting conditions.

Developers can use the available PyTorch inference and post-training scripts along with model checkpoints. Cosmos NIM microservices are in development—Cosmos Predict NIM microservices are available here.


NVIDIA Cosmos World Foundation Models

A family of pretrained models for world generation as videos for accelerating physical AI development. Available openly to developers on NGC, Hugging Face, and GitHub.

Cosmos Predict-2

Our best-performing world foundation model yet—higher fidelity, flexible frame rates and resolutions, fewer hallucinations, and better text, object, and motion control in the video.

Generate previews from text in under 4s and up to 30s of future world video from reference image, or preview.

Cosmos Transfer

For controllable and photorealistic synthetic data at scale.

Input: Segmentation maps, depth signals, lidar scans, key points, trajectories, HD maps, and ground-truth simulations from NVIDIA Omniverseâ„¢.

Output: Photorealistic world scenes, conditioned based on inputs, mirroring layout, object placement, and motion.

Cosmos Reason

For physical AI reasoning.

Fully customizable, multimodal reasoning model trained using visual-language fine-tuning and reinforcement learning that uses a chain of thoughts to plan responses.

The model enables intelligent decision-making by reasoning and rewarding optimal responses.

Cosmos Predict-1

For out-of-the box world generation and post-training.

A generalist model that generates world states from text or video prompts and synthesizes continuous motion by predicting frames between a given start and end frame.

These models range from 4 billion to 15 billion parameters and can be used based on inference requirements.

Cosmos Tokenizers

A suite of image and video tokenizers that advances the state of the art in visual tokenization for world model training.

Cosmos WFM Post-Training Samples

Post-trained Cosmos Predict WFM generates predictive world states for autonomous vehicles, creating single or multi-view videos from ground-truth input for 360° environmental awareness in AV training.

Cosmos Guardrails

A set of guardrails, including a pre-guard to block harmful inputs and a post-guard to ensure safety and consistency in generations.

Cosmos Prompt Upsampler

Transform original input prompts into more detailed and enriched versions for higher-quality outputs from Cosmos WFMs.
