## Summary

NVIDIA has released an open-source framework that enables its Nemotron 3 Ultra model to solve Olympiad-level mathematics problems at a gold-medal standard. The system utilizes a test-time compute pipeline that iteratively generates, verifies, and refines natural-language proofs without relying on formal provers or external tools.

The approach involves training two specialist checkpoints from the base Nemotron 3 Ultra model using supervised fine-tuning and reinforcement learning. By combining these specialists with the general-availability model in an iterative search process, the system achieved a score of 30 out of 42 points at the International Mathematical Olympiad (IMO) 2026, surpassing the threshold for a gold medal.

To support further research, the team has released the post-trained checkpoints, training data, inference code, and submitted solutions. They also introduced Nemotron-IMO-Bench, a new benchmark consisting of 200 novel olympiad-level problems, providing the community with resources to evaluate and improve mathematical reasoning capabilities in large language models.

## Key points

- Nemotron 3 Ultra pipeline scored 30/42 at IMO 2026, meeting the gold-medal threshold.
- System uses iterative natural-language proof generation, verification, and refinement without formal tools.
- NVIDIA released two specialist checkpoints, training data, code, and a new 200-problem benchmark.

## Why it matters

This demonstrates that open-weight models can achieve frontier-level performance in complex mathematical reasoning, lowering the barrier for researchers to develop and evaluate advanced AI systems for rigorous problem-solving tasks.
