DeepSeek R1 vs NVIDIA Nemotron 3 Super

DeepSeek · China  |  NVIDIA · US · Updated June 2026

Quick verdict

Pick DeepSeek R1 for open-weight reasoning model or transparent chain-of-thought. Pick NVIDIA Nemotron 3 Super for high-throughput agentic reasoning (up to 2.2x gpt-oss-120b) or 1m-token context with strong long-context retrieval (91.6% ruler @ 1m). On a tight budget at scale, NVIDIA Nemotron 3 Super is the value pick.

DeepSeek R1 (DeepSeek, China) and NVIDIA Nemotron 3 Super (NVIDIA, US) line up two different AI ecosystems against each other — a comparison that is as much about cost philosophy and openness as raw capability. DeepSeek R1 is the open-weight reasoning model that reset price expectations in early 2025. NVIDIA Nemotron 3 Super is nVIDIA's open 120B-total/12B-active hybrid Mamba-Transformer MoE built for high-throughput agentic reasoning at 1M-token context. They diverge most on price and context window — each quantified below from the models' real specs.

Lowest cost at scale

NVIDIA Nemotron 3 Super

At Open weight (self-host / free), it is the cheaper of the two — the gap dominates the bill on high-volume workloads.

Largest single-prompt input

NVIDIA Nemotron 3 Super

Its 1M window is about 7.8× larger, fitting roughly 1,500 pages in one prompt.

Which should you pick?

A cost-sensitive startup shipping high volume

NVIDIA Nemotron 3 Super

At Open weight (self-host / free) it undercuts DeepSeek R1, and on millions of tokens that margin decides the monthly bill.

Someone analysing very long documents or codebases

NVIDIA Nemotron 3 Super

Larger 1M window fits more in one prompt.

Anyone whose priority is open-weight reasoning model

DeepSeek R1

It is specifically built for that.

Anyone whose priority is high-throughput agentic reasoning (up to 2.2x gpt-oss-120b)

NVIDIA Nemotron 3 Super

That is its strongest area.

DeepSeek R1: where it fits

The open-weight reasoning model that reset price expectations in early 2025. Released January 2025 by DeepSeek, it is built for open-weight reasoning model, transparent chain-of-thought, low cost, and strong maths and code.

Its trade-offs are real: older than V4, smaller 128K context, and text/code focused. At $0.55 in / $2.19 out per million tokens, it sits in the budget price band.

NVIDIA Nemotron 3 Super: where it fits

NVIDIA's open 120B-total/12B-active hybrid Mamba-Transformer MoE built for high-throughput agentic reasoning at 1M-token context. Released March 11, 2026 by NVIDIA, it is built for high-throughput agentic reasoning (up to 2.2x GPT-OSS-120B), 1M-token context with strong long-context retrieval (91.6% RULER @ 1M), strong math reasoning (90.21% AIME 2025), and fully open weights, datasets, and recipes for self-hosting.

Its trade-offs: text-only; no image, audio, or video input, and requires roughly 8x H100-80GB GPUs to self-host at BF16. As an open-weight model, its running cost is your own hardware rather than a per-token fee.

The bottom line for this matchup

This is less "which is smarter" and more "which ecosystem fits." DeepSeek R1 (China) and NVIDIA Nemotron 3 Super (US) differ on pricing philosophy, data-residency, and tooling as much as on raw scores. NVIDIA Nemotron 3 Super is the cheaper option, which matters at volume. The pragmatic move is to run one real task through both and judge the outputs against your own constraints — including where your data is allowed to be processed.

Frequently asked questions

Is DeepSeek R1 or NVIDIA Nemotron 3 Super better for coding?

Public SWE-Bench figures are not available for DeepSeek R1, so the honest test is your own repository — run an identical real bug through both. By design, DeepSeek R1 leans toward open-weight reasoning model while NVIDIA Nemotron 3 Super leans toward high-throughput agentic reasoning (up to 2.2x gpt-oss-120b), and that positioning usually predicts which feels better on your codebase.

Which is cheaper, DeepSeek R1 or NVIDIA Nemotron 3 Super?

NVIDIA Nemotron 3 Super is cheaper — $0.55/$2.19 per 1M tokens vs Open weight (self-host / free).

Which has the bigger context window?

NVIDIA Nemotron 3 Super — 1M vs 128K, about 7.8× larger. Useful only if the model actually reasons over the full window, which not all do.

Can I use both DeepSeek R1 and NVIDIA Nemotron 3 Super together?

Yes — a multi-model platform like LumiChats gives you DeepSeek R1, NVIDIA Nemotron 3 Super and 40+ others under one ₹69/day pass (about $1/day), so you can draft with one and cross-check with the other instead of buying two subscriptions.

Which is newer, DeepSeek R1 or NVIDIA Nemotron 3 Super?

NVIDIA Nemotron 3 Super — released March 11, 2026, about 14 months after DeepSeek R1.
