We introduce *NousCoder-14B*, a competitive programming model post-trained on [Qwen3-14B](https://huggingface.co/Qwen/Qwen3-14B) via reinforcement learning.
On LiveCodeBench v6 (08/01/2024 - 05/01/2025), we achieve a Pass@1 accuracy of 67.87\%, up 7.08\% from the baseline Pass@1 accuracy of 60.79\%
of Qwen3-14B. We trained on 24k verifiable coding problems using 48 B200s over the course of four days.
