XiangJinYu/Zhihu_Qwen2

Model Details

Model Description

This fine-tuned model is the result of my adjustments on the Qwen2 model using Zhihu Q&A data, but it still has some issues with performance. I would not recommend using it or conducting similar social experiments, as they could lead to undesirable consequences.

• Developed by: Jinyu(Isaac)
• Language(s) (NLP): Chinese
