NVIDIA Open-Sources IMO-Gold Recipe: Nemotron 3 Ultra Scores 30/42 at IMO 2026 in Natural Language

An NVIDIA team led by Ivan Moshkov and Igor Gitman released 'An Open Recipe for IMO Gold', a natural-language-only inference pipeline built on Nemotron 3 Ultra that scored 30 out of 42 at IMO 2026, clearing the gold-medal threshold with no formal provers. The drop includes two fine-tuned checkpoints, training data, submitted solutions and Nemotron-IMO-Bench (200 novel olympiad-level problems), giving the open community a reproducible path to IMO-gold reasoning.
