This mannequin achieves state-of-the-art outcomes on a number of rigorous benchmarks, together with the American Invitational Arithmetic Examination (AIME) 2024 and 2025, the Harvard–MIT Arithmetic Match (HMMT) 2024-25, and the Harvard–London–Edinburgh Arithmetic Examination (HLE-Math) collection. In its tool-integrated reasoning (TIR) configuration, OpenMath-Nemotron-32B achieves a mean move@1 rating of 78.4 % on AIME24, with a majority-voting accuracy of 93.3 %, surpassing earlier top-performing fashions by notable margins.
To accommodate completely different inference eventualities, OpenMath-Nemotron-32B helps three distinct modes: chain-of-thought (CoT), tool-integrated reasoning (TIR), and generative resolution choice (GenSelect). In CoT mode, the mannequin generates intermediate reasoning steps earlier than presenting a ultimate reply, attaining a move@1 accuracy of 76.5% on AIME24. When augmented with GenSelect, which produces a number of candidate options and selects probably the most constant reply, the mannequin’s efficiency improves additional, attaining a outstanding 93.3% accuracy on the identical benchmark. These configurations allow customers to steadiness between rationalization richness and reply precision, catering to analysis environments that require transparency in addition to manufacturing settings that prioritize pace and reliability.
Complementing the 32 billion-parameter variant, NVIDIA has additionally launched OpenMath-Nemotron-14B-Kaggle, a 14.8 billion-parameter mannequin fine-tuned on a strategically chosen subset of the OpenMathReasoning dataset to optimize for aggressive efficiency. This model served because the cornerstone of NVIDIA’s first-place resolution within the AIMO-2 Kaggle competitors, a contest that centered on automated problem-solving strategies for superior mathematical challenges. By calibrating the coaching information to emphasise issues reflective of the competitors’s format and issue, the 14B-Kaggle mannequin demonstrated distinctive adaptability, outpacing rival approaches and securing the highest leaderboard place.
Efficiency benchmarks for OpenMath-Nemotron-14B-Kaggle mirror these of its bigger counterpart, with the mannequin attaining a move@1 accuracy of 73.7% on AIME24 in CoT mode and bettering to 86.7% underneath GenSelect protocols. On the AIME25 benchmark, it achieves a move fee of 57.9 % (majority at 64 of 73.3 %), and on HMMT-24-25, it attains 50.5 % (majority at 64 of 64.8 %). These figures spotlight the mannequin’s potential to ship high-quality options, even with a extra compact parameter footprint, making it well-suited for eventualities the place useful resource constraints or inference latency are crucial elements.
Each OpenMath-Nemotron fashions are accompanied by an open‐supply pipeline, enabling full reproducibility of knowledge era, coaching procedures, and analysis protocols. NVIDIA has built-in these workflows into its NeMo-Abilities framework, offering reference implementations for CoT, TIR, and GenSelect inference modes. With instance code snippets that reveal find out how to instantiate a transformer pipeline, configure dtype and machine mapping, and parse mannequin outputs, builders can quickly prototype functions that question these fashions for step-by-step options or streamlined ultimate solutions.
Beneath the hood, each fashions are optimized to run effectively on NVIDIA GPU architectures, starting from the Ampere to the Hopper microarchitectures, leveraging extremely tuned CUDA libraries and TensorRT optimizations. For manufacturing deployments, customers can serve fashions by way of Triton Inference Server, enabling low-latency, high-throughput integrations in internet providers or batch processing pipelines. The adoption of BF16 tensor codecs strikes a really perfect steadiness between numerical precision and reminiscence footprint, enabling these large-scale fashions to suit inside GPU reminiscence constraints whereas sustaining sturdy efficiency throughout numerous {hardware} platforms.
