Eurus-2-7B-SFT Overview
Eurus-2-7B-SFT is a 7.6 billion parameter model from PRIME-RL, built upon the Qwen2.5-Math-7B-Base architecture, known for its strong mathematical capabilities. This model undergoes supervised fine-tuning (SFT) using the Eurus-2-SFT-Data, which is an action-centric chain-of-thought reasoning dataset. The SFT process is designed as a warm-up stage to teach the model effective reasoning patterns, preparing it for subsequent process reinforcement learning (PRIME) stages, such as with Eurus-2-7B-PRIME.
