NVIDIA Nemotron 3 Super vs OLMo 3 32B Think

NVIDIA · US  |  Allen Institute for AI · US · Updated June 2026

Quick verdict

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). Pick OLMo 3 32B Think for the most fully transparent open release available - ai2 publishes the complete weights, full dolma training dataset, every training checkpoint, training logs, and pretraining/instruction-tuning/rl code, not just final weights or a genuine 32b reasoning ('think') model that generates explicit chain-of-thought.

NVIDIA Nemotron 3 Super (NVIDIA) and OLMo 3 32B Think (Allen Institute for AI) are two of the models people most often weigh against each other in 2026. 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. OLMo 3 32B Think is allen Institute for AI's fully-open 32B reasoning model - the rare release that ships the complete training data and process, not just the weights. Their biggest split is context window, and the breakdown below shows exactly how that plays out for your workload.

Who wins what

High-throughput agentic reasoning (up to 2.2x GPT-OSS-120B)

NVIDIA Nemotron 3 Super

NVIDIA's open 120B-total/12B-active hybrid Mamba-Transformer MoE built for high-throughput agentic reasoning at 1M-token context — and it carries the larger 1M context.

1M-token context with strong long-context retrieval (91.6% RULER @ 1M)

NVIDIA Nemotron 3 Super

Its 1M window holds about 15× more than OLMo 3 32B Think's 65K in a single prompt.

Strong math reasoning (90.21% AIME 2025)

NVIDIA Nemotron 3 Super

NVIDIA's open 120B-total/12B-active hybrid Mamba-Transformer MoE built for high-throughput agentic reasoning at 1M-token context — and it is the newer of the two.

The most fully transparent open release available - Ai2 publishes the complete weights, full Dolma training dataset, every training checkpoint, training logs, and pretraining/instruction-tuning/RL code, not just final weights

OLMo 3 32B Think

OLMo 3 32B Think lists the most fully transparent open release available - Ai2 publishes the complete weights, full Dolma training dataset, every training checkpoint, training logs, and pretraining/instruction-tuning/RL code, not just final weights among its strengths; NVIDIA Nemotron 3 Super does not.

A genuine 32B reasoning ('Think') model that generates explicit chain-of-thought

OLMo 3 32B Think

Fully open under Apache 2.0 - free to self-host

OLMo 3 32B Think

OLMo 3 32B Think lists fully open under Apache 2.0 - free to self-host among its strengths; NVIDIA Nemotron 3 Super does not.

Largest single-prompt input

NVIDIA Nemotron 3 Super

Its 1M window is about 15× larger than OLMo 3 32B Think's 65K, fitting roughly 1,500 pages in one prompt.

Which should you pick?

Someone analysing very long documents or codebases

NVIDIA Nemotron 3 Super

Larger 1M window fits more in one prompt.

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

NVIDIA Nemotron 3 Super

It is specifically built for that.

Anyone whose priority is the most fully transparent open release available - ai2 publishes the complete weights, full dolma training dataset, every training checkpoint, training logs, and pretraining/instruction-tuning/rl code, not just final weights

OLMo 3 32B Think

That is its strongest area.

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 are real: 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.

OLMo 3 32B Think: where it fits

Allen Institute for AI's fully-open 32B reasoning model - the rare release that ships the complete training data and process, not just the weights. Released November 20, 2025 by Allen Institute for AI, it is built for the most fully transparent open release available - Ai2 publishes the complete weights, full Dolma training dataset, every training checkpoint, training logs, and pretraining/instruction-tuning/RL code, not just final weights, a genuine 32B reasoning ('Think') model that generates explicit chain-of-thought, fully open under Apache 2.0 - free to self-host, and built specifically to let researchers reproduce and audit exactly how the model was trained.

Its trade-offs: a 65K context window is modest next to million-token frontier models, prioritizes full openness and reproducibility over topping raw capability leaderboards, and 32B scale trails much larger frontier and open MoE models on general benchmarks. As an open-weight model, its running cost is your own hardware rather than a per-token fee.

The bottom line for this matchup

NVIDIA Nemotron 3 Super and OLMo 3 32B Think overlap enough that the right pick depends on your specific job. NVIDIA Nemotron 3 Super holds the larger context; and each leads in its own area — NVIDIA Nemotron 3 Super for high-throughput agentic reasoning (up to 2.2x gpt-oss-120b), OLMo 3 32B Think for the most fully transparent open release available - ai2 publishes the complete weights, full dolma training dataset, every training checkpoint, training logs, and pretraining/instruction-tuning/rl code, not just final weights. Rather than crowning one, run the same hard task through both once and let the results decide.

Frequently asked questions

Is NVIDIA Nemotron 3 Super or OLMo 3 32B Think better for coding?

Public SWE-Bench figures are not available for OLMo 3 32B Think, so the honest test is your own repository — run an identical real bug through both. By design, NVIDIA Nemotron 3 Super leans toward high-throughput agentic reasoning (up to 2.2x gpt-oss-120b) while OLMo 3 32B Think leans toward the most fully transparent open release available - ai2 publishes the complete weights, full dolma training dataset, every training checkpoint, training logs, and pretraining/instruction-tuning/rl code, not just final weights, and that positioning usually predicts which feels better on your codebase.

Which is cheaper, NVIDIA Nemotron 3 Super or OLMo 3 32B Think?

They are priced almost identically, so cost will not decide between them.

Which has the bigger context window?

NVIDIA Nemotron 3 Super — 1M vs 65K, about 15× larger. Useful only if the model actually reasons over the full window, which not all do.

Can I use both NVIDIA Nemotron 3 Super and OLMo 3 32B Think together?

Yes — a multi-model platform like LumiChats gives you NVIDIA Nemotron 3 Super, OLMo 3 32B Think 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, NVIDIA Nemotron 3 Super or OLMo 3 32B Think?

NVIDIA Nemotron 3 Super — released March 11, 2026, about 4 months after OLMo 3 32B Think.
