NJUxlj/prm-reproduce

This repository is a low-traction (3 stars, 0 forks) personal reproduction project that has been stagnant for over 400 days. While the underlying paper from OpenAI is foundational to the current 'reasoning model' era (e.g., o1, DeepSeek-R1), this specific codebase lacks the scale, data, and community momentum to be a viable tool. It functions more as a learning exercise than a production-ready framework. The field has rapidly moved toward more sophisticated implementations integrated into major RLHF libraries like HuggingFace TRL or specialized releases from labs like Skywork (Skywork-Reward) and DeepSeek. Frontier labs have already internalized these capabilities into their primary inference stacks, making standalone, unmaintained PRM clones essentially obsolete for anyone other than students studying the mechanics of step-wise reward modeling.
