Nemotron fine-tuning yields gold-level IOI and IMO results

AI summary

NVIDIA reports that Nemotron 3 was specialized with supervised fine-tuning, reinforcement learning, and iterative generate-evaluate-refine inference to reach gold-medal-level performance at both IOI 2026 and IMO 2026. The IOI system scored above the gold threshold in a live, constraint-matched run, while the IMO system’s proofs were evaluated by official graders.
