🔑 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

🟢 Final GRM — Generative Reward Models

Ready-to-use generative reward models trained with the full RM-NLHF pipeline.

🔵 Cold-Start MetaRM

The cold-start MetaRM described in the paper, used as initial weights for MetaRM.

🟡 Final MetaRM

Final-step MetaRM checkpoints co-trained alongside the generative reward model.

⚪ Baseline — Outcome Reward Model

A baseline trained solely on outcome labels, without natural language critique.
