Their quality depends heavily on the preference data, and open-source preference datasets tend to be noisy or inconsistently labelled. The authors take a data-first approach. Using only public sources (HelpSteer2, OffsetBias, WildGuardMix… 2. **[Skywork-Reward-V2: Scaling Preference Data Curation via Human-AI Synergy](https://md.research.elamur.ai/free/en/papers/liu-2025-skywork-reward-v2-scaling/)** *(2025 · 48 citations)* Open reward models used in RLHF are fragile. High RewardBench scores often fail to carry over to other evaluations, and tweaks to losses or architectures have brought little real progress. The authors argue that the bottleneck is the preference data itself, which is often narrow, synthetically labeled or poorly… ## Co-authors here 11 co-authors with a page, the most papers together first. - [Chaojie Wang](https://md.research.elamur.ai/free/en/authors/chaojie-wang/) ×2 - [Chris Yuhao Liu](https://md.research.elamur.ai/free/en/authors/chris-yuhao-liu/) ×2 - [Jujie He](https://md.research.elamur.ai/free/en/authors/jujie-he/) ×2 - [Liang Zeng](https://md.research.elamur.ai/free/en/authors/liang-zeng/) ×2 - [Rui Yan](https://md.research.elamur.ai/free/en/authors/rui-yan/) ×2 - [Yahui Zhou](https://md.research.elamur.ai/free/en/authors/yahui-zhou/) ×2 - [Yang Liu](https://md.research.elamur.ai/free/en/authors/yang-liu/) ×2 - [Jiacheng Xu](https://md.research.elamur.ai/free/en/authors/jiacheng-xu/) - [Shuicheng Yan](https://md.research.elamur.ai/free/en/authors/shuicheng-yan/) - [Wei Shen](https://md.research.elamur.ai/free/en/authors/wei-shen/) - [Yuzhen Xiao](https://md.research.elamur.ai/free/en/authors/yuzhen-xiao/) ## Cited by Papers of our library cite their works 158 times (of the 149,439 papers whose bibliographies we read); [45 citing papers with a page here →](https://md.research.elamur.ai/free/en/authors/jiacai-liu/cited-by/).
