# 🚀 Can we cast reward modeling as a reasoning task?
|
| 17 |
+
|
| 18 |
+
**RM-R1** is a training framework for *Reasoning Reward Model* (ReasRM) that judges two candidate answers by first **thinking out loud**—generating rubrics or reasoning traces—then emitting its preference.
|
| 19 |
+
Compared with prior scalar or vanilla generative reward models, RM-R1 delivers up to **+13.8 % absolute accuracy gains** on public reward model benchmarks while providing *fully interpretable* critiques.
|
| 20 |
+
|
| 21 |
+
## TL;DR
|
| 22 |
+
* **Two-stage training**
|
| 23 |
+
1. **Distillation** of ~8.7 K high-quality reasoning traces (Chain-of-Rubrics).
|
| 24 |
+
2. **Reinforcement Learning with Verifiable Rewards** (RLVR) on ~64 K preference pairs.
|
| 25 |
+
|
| 26 |
+
* **Backbones** released: 7 B / 14 B / 32 B Qwen-2.5-Instruct variants + DeepSeek-distilled checkpoints.
|
| 27 |
+
|
| 28 |
+
## Intended uses
|
| 29 |
+
* **RLHF / RLAIF**: plug-and-play reward function for policy optimisation.
|
| 30 |
+
* **Automated evaluation**: LLM-as-a-judge for open-domain QA, chat, and reasoning.
|
| 31 |
+
* **Research**: study process supervision, chain-of-thought verification, or rubric generation.
