Nvidia fine-tunes Nemotron to gold-medal level on IOI and IMO

KEY FACTS

  • Nvidia built systems that reach gold-medal level on IOI 2026 and IMO 2026 by fine-tuning its Nemotron 3 model.
  • The IOI test was run under the same real-time conditions as human contestants, but the results were not counted in the official rankings.
  • The IMO system's proofs were graded by official IMO scorers, earning 30 points out of 42, above the gold-medal threshold.
  • The IOI 2026-specific system, Ultra-CC, scored 535.4 points out of 600 in the test.
  • Training used 22,000 programming problems and 414,890 math proof examples.

PHYSIX OBSERVATION

Nvidia used fine-tuning rather than training from scratch to bring Nemotron to gold-medal level in two highly difficult competitions, proving the path of base model plus domain adaptation is viable. For the industry, this means the development cost of specialized AI systems may fall, and users will see AI breakthroughs in professional domains sooner.
