NVIDIA Cosmos

NVIDIA Cosmos is an open platform of world foundation models, frameworks, and libraries for physical AI development. It provides post-training, data processing, optimization, and evaluation tools to accelerate the development of specialized models for robotics, autonomous vehicles, and vision AI agents. The latest release, Cosmos 3, is a frontier foundation model built on a breakthrough Mixture of Transformers architecture that combines an autoregressive reasoning layer with a diffusion-based generation layer — enabling native vision reasoning, world simulation, and action generation in a single model. Cosmos 3 is the #1 open model on Arena Bench, PAI-Bench, R-Bench, and VANTAGE Bench, with leading physics accuracy for world generation and vision AI tasks. Developers can post-train Cosmos on proprietary embodiment, sensor, and environment data using open tools and agentic scripts to build custom robotics policies, AV perception models, and vision AI agents within weeks rather than months.
