JudgeLRM

This Space demonstrates the JudgeLRM model, designed to evaluate the quality of two AI assistant responses. JudgeLRM is a family of judgment-oriented LLMs trained using reinforcement learning (RL) with judge-wise, outcome-driven rewards. JudgeLRM models consistently outperform both SFT-tuned and state-of-the-art reasoning models. Notably, JudgeLRM-3B surpasses GPT-4, and JudgeLRM-7B outperforms DeepSeek-R1 by 2.79\% in F1 score, particularly excelling in judge tasks requiring deep reasoning.

Enter an instruction and two responses, and the model will think, reason and score them on a scale of 1-10 (higher is better).

You can also select Hugging Face models to automatically generate responses for evaluation.
