Not independent measurement

Structured rows reported in this exact model repository at the pinned revision below. They are the publisher talking about itself: never measured evidence, never a score input on their own. They remain quarantined until dataset revision, harness, configuration and identity pass ModelCap’s independent admission review.

These adoption and deployment observations remain context only. They do not change this model's ModelCap Index score or rank.

The bounded 0–100 capability score blends each source’s competitive placement with its published achievement, then combines capability families. Evidence breadth adds a modest uncertainty adjustment; price and popularity are not part of benchmark-led rank.

Nemotron 3 Nano Omni: common questions

How does Nemotron 3 Nano Omni rank among AI models?

Nemotron 3 Nano Omni has no public ModelCap Index position as of 22 September 2026: the snapshot lacks enough matched benchmark evidence, or the identity match is unresolved. Its catalogue facts (price, context, providers) are shown without a rank.

How much does Nemotron 3 Nano Omni cost per 1M tokens?

Nemotron 3 Nano Omni is listed at Free per 1M input tokens and Free per 1M output tokens as of 22 September 2026. Prices come from the OpenRouter catalogue and re-observe on every refresh; at least one provider lists a free tier. For 1,000 requests using 2,000 input and 500 output tokens each, the listed rates imply Free total (2M input + 0.5M output). This excludes caching, batch discounts, prompt-length tiers, tool charges and retries; verify the chosen endpoint's rate and limits before budgeting.

What is the context window of Nemotron 3 Nano Omni?

Nemotron 3 Nano Omni has a published context window of 256K tokens (256,000) and a maximum output of 66K tokens. Individual providers can serve less than the published maximum; the providers table lists each endpoint's own limit.

Is Nemotron 3 Nano Omni open-weight?

Restricted license (nvidia-open-model-agreement). Downloadable weights use a model-specific or use-restricted license. Review the linked license before use, redistribution, or commercial deployment. The repository is nvidia/Nemotron-3-Nano-Omni-30B-A3B-Reasoning-BF16 on Hugging Face.

Which API providers serve Nemotron 3 Nano Omni?

One provider serves Nemotron 3 Nano Omni through OpenRouter as of 22 September 2026: Nvidia. Each provider's price, context limit, quantization and measured uptime are in the providers table above.

When was Nemotron 3 Nano Omni released?

Nemotron 3 Nano Omni first appeared in the catalogue on 28 Apr 2026. It is the current version in its family. Rank and price movements since then are recorded on the site's changes feed.
