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
These models set new state-of-the-art pass@1 scores for their size class across multiple reasoning benchmarks:
| Model | GPQA | MMLU‑PRO | HLE | LiveCodeBench | SciCode | AIME24 | AIME25 | HMMT Feb 2025 |
| 1.5B | 31.6 | 47.5 | 5.5 | 28.6 | 2.2 | 55.5 | 45.6 | 31.5 |
| 7B | 61.1 | 71.9 | 8.3 | 63.3 | 16.2 | 84.7 | 78.2 | 63.5 |
| 14B | 71.6 | 77.5 | 10.1 | 67.8 | 23.5 | 87.8 | 82.0 | 71.2 |
| 32B | 73.1 | 80.0 | 11.9 | 70.2 | 28.5 | 89.2 | 84.0 | 73.8 |
All quoted scores are pass@1 without GenSelect.
🔍 GenSelect (Heavy Mode)
Using Generative Selection with 64 candidates (“GenSelect”), performance further improves, especially at 32B:
- 32B achieves: AIME24 89.2 → 93.3, AIME25 84.0 → 90.0, HMMT 73.8 → 96.7, LiveCodeBench 70.2 → 75.3.
This demonstrates strong emergent reasoning performance at scale.
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:
These models are designed to plug into the NVIDIA NeMo framework, and support TensorRT-LLM, ONNX, and Hugging Face Transformers toolchains, facilitating rapid deployment in production and research settings.
Key Use Cases
- Math tutors and theorem solvers
- Scientific QA agents and medical reasoning systems
- Code generation and debugging assistants
- Chain-of-thought multi-hop question answering
- Synthetic data generation for structured domains
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.
