We adopt the Octothinker to build strong reasoning foundations. Our model's training consists of two phases: a mid-training stable phase on 200 billion tokens from a mathematical corpus, followed by a 20 billion token decay phase. Subsequently, we fine-tune the model on the Infinity-Instruct dataset to achieve superior instruction-following capabilities. This model is open-sourced as a baseline for future experiments, such as enhancing the reasoning capabilities of small models through reinforcement learning. The model architecture is the same as the OpenSeek-Small-v1 model.
