These skip the value model and estimate advantages from group rewards. ByteDance Seed's VAPO argues that a learned value model has more potential, because it gives per-token credit assignment and lower-variance estimates… ## Co-authors here 12 of 14 co-authors with a page, the most papers together first. - [Ruofei Zhu](https://md.research.elamur.ai/free/en/authors/ruofei-zhu/) ×2 - [Tiantian Fan](https://md.research.elamur.ai/free/en/authors/tiantian-fan/) ×2 - [Xiaochen Zuo](https://md.research.elamur.ai/free/en/authors/xiaochen-zuo/) ×2 - [Yu Yue](https://md.research.elamur.ai/free/en/authors/yu-yue/) ×2 - [Yufeng Yuan](https://md.research.elamur.ai/free/en/authors/yufeng-yuan/) ×2 - [Chengyi Wang](https://md.research.elamur.ai/free/en/authors/chengyi-wang/) - [Haibin Lin](https://md.research.elamur.ai/free/en/authors/haibin-lin/) - [Jiaze Chen](https://md.research.elamur.ai/free/en/authors/jiaze-chen/) - [Lingjun Liu](https://md.research.elamur.ai/free/en/authors/lingjun-liu/) - [Wenyuan Xu](https://md.research.elamur.ai/free/en/authors/wenyuan-xu/) - [Xiangpeng Wei](https://md.research.elamur.ai/free/en/authors/xiangpeng-wei/) - [Xin Liu](https://md.research.elamur.ai/free/en/authors/xin-liu/) ## Cited by Papers of our library cite their works 719 times (of the 149,439 papers whose bibliographies we read); [233 citing papers with a page here →](https://md.research.elamur.ai/free/en/authors/qiying-yu/cited-by/).
