TIPS-Qwen3-4B-Thinking-2507-Math
This TIPS math checkpoint is initialized from Qwen/Qwen3-4B-Thinking-2507 and trained with outcome-only GRPO. It is a generative reward model that reasons over a mathematical solution before producing step-level and outcome labels.
Training data and code are available at https://huggingface.co/datasets/XingYing-stack/TIPS-Training-Data and https://github.com/RUCBM/TIPS.
Use the prompt templates and evaluation scripts in the TIPS repository. This checkpoint is intended for reward modeling and process verification rather than general-purpose chat.
