nvidia-cosmos-video

nvidia-cosmos-video is a skill for Claude Code, Codex from calesthio/generative-media-skills. It costs 97 tokens per session (6,830 once invoked), scanned A, original, MIT.

A guide to NVIDIA Cosmos, a system for generating and simulating videos of worlds, actions, and physical environments. It covers hosted services, local models, and inputs such as text, images, video, audio, and actions.

In plain words
What is it for?
Use it to create or transform world-video scenes, generate multiview or action-conditioned footage, and plan local or hosted deployments.
Why use it?
It helps you choose the right Cosmos model and runtime while avoiding assumptions about physics accuracy, model compatibility, hardware, or licensing.

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

    Fix: Remove offensive tool references and exploit code. Legitimate agent skills should not contain penetration testing tools, exploit frameworks, or reconnaissance utilities.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

nvidia-cosmos-video scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

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
Predict2 / Predict1 / Transfer1 Earlier families Varying text/image/video/control contracts Predict2 repository is archived and explicitly recommends migration to Predict2.5. Predict1 remains available in NIM. No public universal EOL date was found; call these earlier/legacy, not unsupported unless the exact artifact says so
Cosmos Reason, Embed, Tokenizer, Curator, Evaluator Reasoning, embeddings, compression/data/evaluation Not a video-generation endpoint Do not route a generation request to these merely because they carry the Cosmos name

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

nvidia-cosmos-video is a skill published in the GitHub repository calesthio/generative-media-skills (170 stars, last pushed 2mo ago), licensed MIT. It adds 97 tokens to every session and 6,830 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
