NVIDIA-Nemotron-Labs-3-Competitive-Coding
An open-source large model from NVIDIA specialized for competitive programming tasks, fine-tuned from Nemotron-3-Ultra-550B-A55B. It employs a Mixture-of-Experts architecture with 550B total parameters and 55B activated parameters, and is focused on algorithmic competition programming tasks.
Timeline (last 90 days)
NVIDIA released a competition programming-specific model named NVIDIA-Nemotron-Labs-3-Competitive-Coding on Hugging Face.
The model has 550 billion parameters, activates 55 billion parameters, uses a 550B-A55B architecture, and is an open-source model.
NVIDIA officially claims the model became the first AI system to score higher than the top human contestant on the IOI problem set.
The team performed one epoch of fine-tuning on 477,642 synthetic reasoning trajectories distilled from GLM-5.2, covering 22,000 curated problems spanning 16 competitive programming contest systems.
The model was evaluated in real time on the IOI 2026 problem set, adhering to official time limits, internet access, and submission constraints, ultimately achieving a score of 535.4 out of 600.
The model's score of 535.4 far exceeds the IOI gold medal threshold of 361.12 and surpasses the top human contestant's score of 498.27 in that competition.
These performance figures all come from NVIDIA's official model documentation and have not yet been fully reproduced and verified by an independent third party.
