NVIDIA Cosmos

NVIDIA's open world foundation model for physical AI. Cosmos 3 (launched May 2026 at GTC Taipei) uses a mixture-of-transformers architecture combining vision reasoning, world generation, and action prediction. The world's first fully open omnimodel — natively understands and generates text, image, video, ambient sound, and actions.

Variants: Cosmos 3 Super (highest accuracy), Cosmos 3 Nano (fast), Cosmos 3 Edge (4B params, on-device). #1 on Artificial Analysis, Physics-IQ, PAI-Bench, R-Bench, RoboArena, VANTAGE-Bench.

Key facts

Cosmos 3 launch (primary NVIDIA)
NVIDIA's May 31 2026 newsroom release, datelined GTC Taipei, says the company launched Cosmos 3 as an open world foundation model for physical AI on a mixture-of-transformers architecture that combines vision reasoning, world generation, and action prediction. NVIDIA calls Cosmos 3 the world's first fully open omnimodel that can natively understand and generate text, images, video, ambient sound, and actions. Treat the 'world's first' and leaderboard claims as NVIDIA-stated (NVIDIA Newsroom)
Cosmos 3 lineup and availability (primary NVIDIA)
The same release says Cosmos 3 Super and Cosmos 3 Nano are available now, with Cosmos 3 Edge coming soon for real-time inference. Developers can try Cosmos 3 on build.nvidia.com, download open models from Hugging Face, and deploy them as NVIDIA NIM microservices. Super is described for highest physics accuracy; Nano for faster video and action reasoning; Edge for edge inference. Frame availability as NVIDIA-stated at launch (NVIDIA Newsroom)
Cosmos Coalition (primary NVIDIA)
NVIDIA also announced the Cosmos Coalition, naming founding members Agile Robots, Black Forest Labs, Generalist, LTX, Runway, and Skild AI. The release lists additional builders on the platform including Doosan Robotics, LG Electronics, Samsung Electronics, and Li Auto. Treat membership as NVIDIA-stated (NVIDIA Newsroom)
World foundation model platform
NVIDIA describes Cosmos as a platform of generative world foundation models for developing physical AI systems in robotics and autonomous machines (NVIDIA Cosmos launch).
Physical AI development
NVIDIA's Cosmos product page says the platform provides world models and tools for physical AI development across robotics and autonomous systems (NVIDIA Cosmos).
Cosmos 3 modalities
NVIDIA's Cosmos 3 documentation says the family jointly processes and generates language, images, video, audio, and action sequences using a unified Mixture-of-Transformers architecture for Physical AI (Cosmos 3 documentation).
Cosmos 3 open research release
The Cosmos 3 technical report says NVIDIA is releasing code, checkpoints, curated synthetic datasets, and an evaluation benchmark under the OpenMDW-1.1 license; availability and license are NVIDIA-stated (Cosmos 3 technical report).
Physical AI foundation models
NVIDIA describes Cosmos as a developer-first platform with world foundation models, video tokenizers, and data-processing tools for physical AI systems such as robots and autonomous vehicles (Cosmos introduction).

Who developed NVIDIA Cosmos?
NVIDIA Cosmos is credited to NVIDIA on the DEPLOY registry. Each developer attribution is verified via primary sources.
Is NVIDIA Cosmos open source?
Yes. NVIDIA Cosmos is recorded as open-source / open-weights on the DEPLOY registry, meaning model weights or source code are publicly available.
What type of AI is NVIDIA Cosmos?
NVIDIA Cosmos is a world model, built on a Transformer-based world model with text-to-world and video-to-world prediction. Cosmos-3 Edge runs on single H200 GPU. architecture on the DEPLOY registry.
What is NVIDIA Cosmos's maturity stage?
NVIDIA Cosmos is at the commercial stage on the DEPLOY maturity ladder. Commercial stage means production-grade deployments are operating at named customer sites.
Which robots run on NVIDIA Cosmos?
No robot models on the DEPLOY registry are recorded as running NVIDIA Cosmos. DEPLOY wires brain-to-model connections only when the wiring is verifiable from primary sources; absence may reflect pre-deployment or unverified manufacturer claims.
