miulab/Qwen3-4B-Usefulness
miulab/Qwen3-4B-Usefulness is a 4 billion parameter language model developed by miulab, fine-tuned for evaluating the usefulness of responses to questions. This model excels at determining if a given response is relevant and helpful, achieving high accuracy (89.83%) and F1 scores (84.21%) in direct answer evaluations. It is specifically designed for assessing response quality in both reasoning (Chain-of-Thought) and direct answer formats, making it suitable for quality assurance and evaluation tasks.

Model Overview
miulab/Qwen3-4B-Usefulness is a 4 billion parameter language model specifically designed and fine-tuned to evaluate the "usefulness" of a given response to a question. This model aims to provide a robust mechanism for assessing response quality, distinguishing itself by focusing on the practical utility of generated text.
Key Capabilities
- Response Usefulness Evaluation: The model can determine whether a provided response is useful to a given question, operating in two distinct modes:
- Reasoning Mode (Chain-of-Thought): Evaluates usefulness by first generating a reasoning step before providing a YES/NO answer. It demonstrates high average scores (0.8438) and low deviation (1.38% CV) across evaluations.
- Direct Answer Mode: Provides a straightforward YES/NO assessment of usefulness. In this mode, the model achieves an accuracy of 89.83% and an F1 Score of 84.21% on 236 samples, indicating strong performance in direct utility assessment.
- Quality Assurance: Its primary strength lies in its ability to act as an automated judge for response quality, making it valuable for filtering or ranking generated content.
Use Cases
This model is particularly well-suited for applications requiring automated evaluation of text generation. Developers can integrate it to:
- Filter irrelevant or unhelpful AI-generated responses.
- Rank multiple responses based on their perceived usefulness.
- Automate quality control in conversational AI systems or content generation pipelines.
- Benchmark the utility of different language models' outputs.
