Select, run, and govern NVIDIA Cosmos world-video generation across Cosmos 3 Generator, Predict2.5, Transfer2.5, downloadable checkpoints, self-hosted NIMs, and hosted preview surfaces. Use for text/image/video-to-world, controlled world transfer, multiview or action-conditioned physical-AI video, local checkpoint pinning, hardware planning, inference approval, and output validation; do not use for Cosmos Reason/Embed-only tasks.

# NVIDIA Cosmos video

Use Cosmos as a **world-generation and world-simulation system**, not as proof of physics. Choose the task, artifact, and runtime together. Names, schemas, licenses, parameter counts, and hardware claims are surface-specific.

This guide was verified against first-party NVIDIA repositories, model cards, NIM documentation, licenses, and technical reports on **2026-07-10**. Recheck every linked model card, release note, support matrix, and embedded license immediately before downloading, deploying, post-training, or serving.

## Route by family and task

| Family/artifact | What it does | Inputs and outputs | Status/boundary |
|---|---|---|---|
| **Cosmos 3 Generator** (`Cosmos3-Nano`, `Cosmos3-Super`) | General omnimodal world generation; text/image to video, and on supported open runtimes video, sound, and action modes | Full open checkpoint cards describe text/image/video/audio/action input and image/video/audio/action output | Newest open family, released 2026-05-31. Use Generator for media; the separate Reasoner produces text reasoning, not video |
| **Cosmos3-Super-Image2Video** | Specialized image-to-video checkpoint | One image + text → video | Do not assume Nano/Super and this specialization are interchangeable |
| **Cosmos-Predict2.5 2B/14B** | Future-world prediction, unified Text2World/Image2World/Video2World; specialized AV/robot variants | Text plus optional first image/video; some variants consume actions or multiview inputs | Current Predict2.5 repository; 2B and 14B pre-trained/post-trained bases, distilled and domain checkpoints have different capabilities |
| **Cosmos-Transfer2.5-2B** | World-to-world transformation with structural control | Source RGB video + prompt + edge/depth/segmentation/visual-blur controls → transformed video | Current control model; use for Sim2Real/Real2Real structure preservation, not unconstrained text-to-video |
