Nemotron Labs 3 Competitive Coding
Nemotron Labs 3 Competitive Coding is an open-weight NVIDIA language-model release. A competitive-programming specialist trained from the Nemotron 3 Ultra base model with supervised learning and reasoning reinforcement learning. It generates candidate algorithmic solutions and supports research on difficult coding contests. The public checkpoint is NVFP4. Contest results involving multiple candidate searches or GenCorrect evaluate a system rather than a single response. The license permits commercial and non-commercial use subject to its published terms.
