Co-rewarding-III-Qwen3-4B-Base-MATH

Co-rewarding-III-Qwen3-4B-Base:

This repository is the Co-rewarding-III-Qwen3-4B-Base-MATH model, a Qwen3-4B-Base model fine-tuned using the Co-rewarding-III method on the MATH training set. The model was presented in the paper Co-rewarding: Stable Self-supervised RL for Eliciting Reasoning in Large Language Models.

For more details about the Co-rewarding framework and its implementation, you can refer to our GitHub Repository: https://github.com/tmlr-group/Co-rewarding.
