miulab/Qwen3-1.7B-Usefulness
The miulab/Qwen3-1.7B-Usefulness model is a 1.7 billion parameter Qwen3-based language model developed by miulab, specifically fine-tuned to predict the usefulness of a response to a given question. It functions as a judge model, determining if a response directly answers a question or avoids it, achieving an average F1 score of 0.8248 in reasoning mode and 0.7681 in direct answer mode. This model is optimized for evaluating the relevance and directness of AI-generated or human responses.

Model Overview
The miulab/Qwen3-1.7B-Usefulness model is a specialized 1.7 billion parameter Qwen3-based language model designed to act as a "usefulness judge." Its primary function is to evaluate whether a given response effectively answers a question or if it avoids the core query. This model is particularly useful for assessing the quality and directness of conversational AI outputs or other text-based interactions.
Key Capabilities
- Response Usefulness Prediction: Determines if a response is useful to a question, distinguishing between direct answers and evasive responses.
- Reasoning Mode: Can provide a reasoning step before delivering a YES/NO judgment, achieving an average F1 score of 0.8248 with low deviation (StdDev 0.0226) over multiple evaluations.
- Direct Answer Mode: Offers a straightforward YES/NO judgment, demonstrating an accuracy of 0.8644 and an F1 score of 0.7681.
- Qwen3 Architecture: Built upon the Qwen3 model family, leveraging its foundational language understanding capabilities.
Good For
- Automated Response Evaluation: Ideal for systems that need to automatically check the relevance and directness of generated text.
- Quality Assurance: Can be integrated into pipelines to ensure AI models provide pertinent answers.
- Benchmarking: Useful for researchers and developers to quantitatively assess the "usefulness" aspect of different language models or response generation strategies.
