Overview
taki555/Qwen3-4B-Instruct-2507-Art is a 4 billion parameter instruction-tuned model, a CoT (Chain-of-Thought) efficient version of the Qwen3-4B-Instruct-2507. Developed by Taiqiang Wu, Zenan Xu, Bo Zhou, and Ngai Wong, this model is the result of research detailed in the paper "The Art of Efficient Reasoning: Data, Reward, and Optimization". Its core innovation lies in its ability to generate accurate reasoning trajectories that are significantly shorter than typical CoT outputs, thereby reducing computational costs.
