Nemotron Labs Ultra Math
Nemotron Labs Ultra Math is an open-weight NVIDIA language-model release. NVIDIA’s released olympiad mathematics specialists build on Nemotron 3 Ultra for rigorous proof generation, checking, and self-evaluation. The SFT and reinforcement-learning checkpoints are grouped here. They were used in an ensemble with inference-time scaling for IMO-level problem solving; ensemble medal-level claims are not standalone model accuracy. The license permits commercial and non-commercial use subject to its published terms.
