NousCoder-14B: Advancing Competitive Programming

NousCoder-14B is a new competitive programming model developed by NousResearch, which has been enhanced through reinforcement learning from its predecessor, Qwen3-14B. It demonstrates a significant improvement in performance, achieving a Pass@1 accuracy of 67.87% on the LiveCodeBench v6, marking a 7.08% increase from Qwen3-14B’s baseline accuracy. This advancement was accomplished by training on 24,000 verifiable coding problems using 48 B200s over four days. The improvement in coding model accuracy is crucial for advancing AI’s capability in solving complex programming tasks efficiently.

NousCoder-14B represents a significant advancement in the field of competitive programming models. By leveraging reinforcement learning techniques, it has been post-trained on the Qwen3-14B model, resulting in a notable increase in performance. Specifically, the model achieves a Pass@1 accuracy of 67.87% on LiveCodeBench v6, which is a substantial improvement over the baseline accuracy of 60.79% achieved by Qwen3-14B. This enhancement is crucial as it demonstrates the potential of reinforcement learning to refine and optimize existing models, leading to more accurate and efficient problem-solving capabilities in competitive programming.

The training process for NousCoder-14B involved using 24,000 verifiable coding problems, which provided a robust dataset for the model to learn from. The use of 48 B200s over four days underscores the computational power and resources required to develop such an advanced model.
