Their recent results show that Nemotron is a strong, adaptable foundation for building world-class specialist models.
Key facts
- Nemotron-3-Nano-CC, with 30 billion total parameters and 3 billion active parameters, received both SFT and RL
- Nano improved from 130 points before post-training to 280 after SFT and 291 after RL
- That finding guided the competition-specific Ultra-CC system used for IOI 2026, which scored 535.4 out of 600
- The Nemotron Labs IMO 2026 collection brings together the SFT and RL checkpoints, both training datasets, and Nemotron-IMO-Bench, a new benchmark of 200 olympiad-level problems
Summary
The IOI result came from a live, prospective run under the same time, internet-access, and submission constraints as human contestants. Across the two projects, that recipe had four parts:. Apply standard post-training methods such as SFT and, where useful, RL. Pair the specialist model with an inference loop that generates, evaluates, and improves candidate answers.
