R3-Qwen3-14B-4k
R3-Qwen3-14B-4k is part of the R3 family, a series of Robust Rubric-Agnostic Reward Models. We perform SFT on the Qwen3 model family on the 4B, 8B, and 14B scales as well as on Phi-4-reasoning plus. Check out our paper for more information!
Model description
- Model type: A reward model trained on a curated R3 dataset collected from 45 diverse sources that covers tasks such as classification, preference optimization, and question answering. Each example in the dataset contains an instruction and task description, input, response(s), evaluation rubrics, and a score along with the corresponding reasoning.
- Language(s) (NLP): English

- Finetuned from model: Qwen/Qwen3-14B
