Nvidia Releases Cosmos 3, Tops Open-Weight Text-to-Image, Image-to-Video Rankings
Nvidia released Cosmos 3, an open omnimodal world-model family for physical AI that combines vision reasoning, world generation and action generation, and its fine-tuned Cosmos3-Super variants ranked No. 1 among open-weight models on Artificial Analysis in text-to-image and image-to-video. Nvidia and benchmark posts described the system as a Mixture-of-Transformers architecture pairing an autoregressive reasoner with a diffusion generator across language, image, video, audio and action.
The company is positioning Cosmos 3 for robotics and autonomous systems, and said it also leads open-model benchmarks including Physics-IQ, PAI-Bench, R-Bench, RoboLab, RoboArena, VANTAGE-Bench and TAR. Nvidia also launched the Cosmos Coalition, with Runway among the founding members, to build and open-source frontier world models for physical AI; Artificial Analysis said reproducing the leaderboard results requires structured JSON prompts and prompt upsampling, with first- and third-party APIs expected in the next few weeks.

@kimmonismus1/ NVIDIA just open-sourced Cosmos 3 at GTC Taipei! It's the first fully open "omnimodel" for physical AI - one model that understands the real world, predicts what happens next, and generates the actions a robot should take. Weights, cod
@kimmonismus2/ What changed: old Cosmos split the work across separate models — one to understand a scene, one to generate video, one for controlled simulation. Cosmos 3 fuses everything into a single Mixture-of-Transformers with two towers: → a reason

@kimmonismus8/ Jensen's framing: the "big bang of physical AI" is just around the corner. Hype aside, this is the most serious open-source move in robotics yet. Data was the wall. Cosmos 3 is NVIDIA trying to knock it down — in the open.
