NVIDIA AI has introduced OpenReasoning-Nemotron, a family of large language models (LLMs) designed to excel in complex reasoning tasks across mathematics, science, and code. This model suite—comprising 1.5B, 7B, 14B, and 32B parameter versions—has been distilled from the 671B DeepSeek R1 0528 model, capturing its high-level reasoning capabilities in significantly smaller and more efficient models.
The release positions NVIDIA as a leading contributor to the open-source LLM ecosystem, delivering models that push state-of-the-art (SOTA) performance while remaining commercially permissive and widely accessible via Hugging Face.
Model Overview and Architecture
Distillation from DeepSeek R1 0528 (671B)
At the heart of OpenReasoning-Nemotron lies a distillation strategy that transfers reasoning ability from DeepSeek R1—a massive 671B parameter model—into smaller architectures. The process prioritizes reasoning generalization over raw token prediction, enabling compact models to perform effectively on structured, high-cognition tasks.
The distillation dataset emphasizes mathematics, science, and programming languages, aligning model capabilities with key reasoning domains.

Performance Benchmarks
OpenReasoning-Nemotron models outperform their size-equivalent peers on a wide range of reasoning-specific benchmarks, particularly in:
- Mathematics: GSM8K, MATH, and MMLU (math subset)Scientific QA: ARC, OpenBookQA, and PubMedQAProgramming/Code: HumanEval and MBPP
| Model | GSM8K Accuracy | HumanEval Pass@1 | ARC-challenge | MATH |
|---|---|---|---|---|
| 7B | 66.7% | 34.2% | 77.3% | 40.5% |
| 14B | 72.9% | 42.0% | 80.1% | 47.6% |
| 32B | 77.5% | 49.5% | 83.9% | 52.3% |
All metrics represent best-of evaluations under 0-shot or few-shot settings.
These results outperform LLaMA2, Mixtral, and DeepSeek-Coder at similar scales, underscoring the strength of the reasoning-focused distillation method.
Training Data and Reasoning Specialization
The training corpus is a distilled, high-quality subset of the DeepSeek R1 0528 dataset. Key features include:
- Heavily curated reasoning data from math, science, and CS disciplines.Prompt-engineered fine-tuning designed to reinforce multi-step thought chains.Emphasis on logical consistency, constraint satisfaction, and symbolic reasoning.
This deliberate curation ensures strong alignment with real-world reasoning problems found in both academia and applied ML domains.
Open and Ecosystem Integration
All four OpenReasoning-Nemotron models are released under an open and commercially permissive license, with model cards, evaluation scripts, and inference-ready weights available on Hugging Face:

Conclusion
NVIDIA’s OpenReasoning-Nemotron models offer a pragmatic, open-source path toward scaling reasoning ability without frontier-scale compute costs. By distilling from the 671B DeepSeek R1 and targeting high-leverage reasoning domains, these models deliver a powerful balance of accuracy, efficiency, and accessibility.
For developers, researchers, and enterprises working on logic-intensive AI applications, OpenReasoning-Nemotron provides a compelling foundation—free from the trade-offs that often accompany proprietary or overgeneralized models.
Frequently Asked Questions (FAQs)
1. What is the difference between OpenReasoning-Nemotron and general-purpose LLMs like LLaMA or Mixtral?
OpenReasoning-Nemotron models are specifically distilled to enhance reasoning in math, science, and code. While LLaMA and Mixtral are trained on broad web corpora, OpenReasoning models emphasize symbolic and multi-step logic, outperforming general-purpose LLMs on domain-specific reasoning benchmarks.
2. How were these models distilled from the 671B DeepSeek R1 0528 model?
The distillation process used high-quality outputs from DeepSeek R1 to guide smaller models during training. This includes a curated reasoning-focused dataset and prompt-based training, allowing the smaller Nemotron variants to replicate the reasoning behavior of a much larger model.
3. Are the OpenReasoning-Nemotron models suitable for commercial use?
Yes. All models in the suite are released with commercially permissive licenses and can be deployed in enterprise environments using NVIDIA’s NeMo, TensorRT-LLM, or Hugging Face Transformers toolkits.
4. Which model size should I use for my application?
- 1.5B: Lightweight tasks, edge inference7B: Balanced for academic use or code assistants14B: High reasoning tasks with moderate latency32B: Near frontier-level performance for R&D or production-grade reasoning agents
