💡 Reward Modeling from Natural Language Human Feedback

RM-NLHF Paper on arXiv

Github

This is the official model repository for the paper "Reward Modeling from Natural Language Human Feedback".

🔑 Key Features

🥇 First generative reward modeling approach that leverages natural language human critique as training signal.
🤝 Hybrid training strategy — jointly utilizes human-written critiques and a specially trained MetaRM for samples without human annotations, achieving SOTA generative reward modeling performance.

💾 Checkpoints

We release multiple model variants. All checkpoints are available in our collection:

📦 Collection: Tongyi-ConvAI/rm-nlhf
