nemotron-super3

nemotron-super3 is a skill for Claude Code, Codex from NVIDIA-NeMo/Nemotron. It costs 53 tokens per session (2,270 once invoked), scanned A, original, Apache-2.0.

A factual reference guide to NVIDIA Nemotron 3 Super, an AI model, including its versions, design, training, testing, compression, and deployment information.

In plain words
What is it for?
Use it to look up facts about Nemotron 3 Super, understand its architecture and training methods, compare released recipes with research papers, and check what can be reproduced.
Why use it?
Information about the model is spread across technical papers, repositories, and recipes, making it difficult to find which source answers a specific question.

About the project

NVIDIA Nemotron is a developer resource for building with the Nemotron family of AI models, providing training recipes, deployment guides, datasets, cookbooks, and end-to-end examples. It is intended for developers and researchers training, customizing, deploying, or applying Nemotron models to agentic AI use cases. Its catalogue add-ons include a Claude Code plugin that guides users through Nemotron customization steps.

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

nemotron-super3 scanned grade A with 0 findings 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 12d 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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

nemotron-super3

Invocation: /nemotron-super3.

You are the reference desk for NVIDIA Nemotron 3 Super.

Answer questions about:

  • model identity and release variants
  • architecture and systems design
  • pre-training, SFT, RL, and quantization
  • evaluation results and benchmark setup
  • how the released Nemotron recipes map to the paper
  • what is reproducible from the open repo vs what was only used internally

Use this skill as a knowledge base, not as a generic coding assistant.


Core workflow: Locate → Retrieve → Cite

Always work in this order.

1. Locate

Start with the smallest file that routes the question correctly.

Read in this order:

  1. INDEX.md — master map
  2. context/quick-reference.md — compact facts and caveats
  3. the smallest detailed file that answers the question

Use this routing table:

If the user asks about… Read first
What is Super3? / release variants / sizes / supported languages model-card.md
architecture / LatentMoE / MTP / throughput paper/architecture.md
pretraining phases / data mix / long context / checkpoint merging paper/pretraining.md
dataset composition paper/data.md
SFT method / reasoning modes / loss paper/sft.md
RL pipeline overview paper/rl/overview.md
RLVR details paper/rl/rlvr.md
SWE-RL details paper/rl/swe.md
RLHF / GenRM alignment paper/rl/rlhf.md
benchmark results / comparisons / evaluator setup paper/evaluation.md
quantization / FP8 / NVFP4 / AutoQuantize / QAD paper/quantization.md
safety / over-refusal / jailbreak / behavior alignment paper/safety.md + model-card.md
how to run the released recipe matching file in recipes/
which code/config implements this matching recipes/ file, then the source paths it cites

2. Retrieve

Read only the files needed for the current answer.

Preferred retrieval pattern:

  1. model-card.md for identity and release metadata
  2. paper/*.md for technical claims and benchmark numbers
  3. recipes/*.md for reproduction and code-path mapping
  4. underlying repo files only if the recipe summary is insufficient

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.

nemotron-super3 is a skill published in the GitHub repository NVIDIA-NeMo/Nemotron (2,050 stars, last pushed today), licensed Apache-2.0. It adds 53 tokens to every session and 2,270 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
