Merged summary
TL;DR - Researchers developed a post-training and test-time refinement pipeline that enabled Nemotron models to achieve gold-medal-level competitive programming performance. Their specialized Ultra-CC system scored 535.4/600 on IOI 2026, surpassing both the gold threshold and the top human score under equivalent competition constraints.
- The pipeline combines 22,000 curated problems, synthetic reasoning traces, supervised fine-tuning, and reinforcement learning.
- GenCorrect iteratively generates, evaluates, and refines diverse candidate solutions using additional test-time compute.
- On IOI 2025, Nano-CC rose from 130 to 291 points after post-training and reached 468 with GenCorrect; Ultra-CC scored 502.
- On IOI 2026, the competition-specific Ultra-CC system exceeded the top human score of 498.27 while observing the same time, internet-access, and submission constraints.
