NVIDIA releases Cosmos 3 with Super‑Text2Image and...
NVIDIA’s Cosmos 3 isn’t just another model drop. It’s a two-tower mixture-of-transformers foundation model that fuses physical reasoning, world generation, and action generation into a single unified framework. The implications are immediate: Super-Text2Image, Super-Image2Video, and Nano-Policy-DROID stretch across modalities, text, image, video, JSON action arrays, while outputs range from visuals to synchronized sound and action states.
Benchmarks tell the story: Nano and Super lead VANTAGE-Bench at their tiers, Cosmos 3 tops TAR, and it claims open-source SOTA on R-Bench. Everything ships open, checkpoints, six SDG datasets, training recipes, action modes, under the OpenMDW-1.1 license. Deployment is production-ready via NIM microservices with BF16, FP8, NVFP4 quantization.
This is a leap beyond generation into embodied intelligence.
Robots and vehicles need to perceive, predict, and then act. Earlier Cosmos releases split these jobs across separate models. Cosmos 3 unifies them with a Mixture-of-Transformers (MoT) architecture.
Cosmos 3 is not just another model release, it is a declaration of intent. By unifying reasoning, generation, and action under one architecture, NVIDIA has collapsed what were once separate disciplines into a single, coherent system. The benchmarks speak for themselves: state-of-the-art on R-Bench, top of the leaderboard on TAR, and leading open-source results across both text-to-image and image-to-video.
But the real story is in the details. A two-tower mixture-of-transformers that ingests text, image, video, and JSON action arrays, and outputs not just pixels, but sound, action states, and policy decisions. The open release of checkpoints, six SDG datasets, and training recipes ensures this isn’t a black box.
It’s a foundation you can build on. Whether you deploy the Reasoner NIM today or wait for the Generator, the path from simulation to real-world robotics has never been more direct. Cosmos 3 arrives as a bridge, between physical reasoning and generation, between research and production, between what a model can see and what it can do.
The long arc of embodied AI now has a unified starting point.

Common Questions Answered
What is the two-tower mixture-of-transformers architecture in NVIDIA's Cosmos 3?
Cosmos 3 uses a two-tower mixture-of-transformers foundation model that unifies physical reasoning, world generation, and action generation into a single framework. This architecture allows the model to process multiple modalities including text, images, videos, and JSON action arrays while maintaining coherent outputs across different domains.
What are the main capabilities of Super-Text2Image and Nano-Policy-DROID in Cosmos 3?
Super-Text2Image and Nano-Policy-DROID are key components of Cosmos 3 that stretch across different modalities and output types. These capabilities enable the model to generate synchronized visuals, sound, and action states from various input formats, demonstrating NVIDIA's unified approach to multimodal generation.
How does Cosmos 3 perform on benchmark tests compared to other models?
Cosmos 3 achieves state-of-the-art results on R-Bench, leads the leaderboard on TAR, and delivers top-performing open-source results across both text-to-image and image-to-video tasks. The Nano and Super variants of Cosmos 3 demonstrate competitive performance across these diverse benchmarking standards.
What problem does Cosmos 3 solve by collapsing separate disciplines into one architecture?
Cosmos 3 unifies what were previously separate disciplines—reasoning, generation, and action—into a single coherent system. This integration eliminates the need for multiple specialized models and creates a more efficient framework for handling complex multimodal tasks that require coordination between physical understanding, content generation, and actionable outputs.
