NVIDIA's open Nemotron 3 Ultra hits IMO gold with 30/42, releases full training recipe
mark_k · x · 2026-09-13
NVIDIA's newly open-sourced Nemotron 3 Ultra system scored 30/42 at the 2026 International Mathematical Olympiad, a gold-medal-level result:
- Natural-language proofs only — no formal theorem provers, external tools, or internet access.
- Three specialist checkpoints generate, verify, and refine candidate proofs before a high-compute stage selects the final answer.
- NVIDIA released everything: the two specialist checkpoints, training data, training and inference code, submitted solutions, and a new 200-problem olympiad-level benchmark.
The full reproducible recipe being open is arguably the bigger story than the gold medal itself.
