Model Description

Q-Judger is a vision-language model fine-tuned specifically for automated evaluation of text-to-image generated images. Given a text prompt and a generated image, the model evaluates the image on fine-grained quality criteria organized in a 3-level hierarchy and outputs structured JSON scores.

• Base Model: Qwen3.6-27B
• Task: Image quality evaluation / judging
• Input: Text prompt + generated image
• Output: Structured JSON with per-dimension scores (0 = Fail, 1 = Pass, 2 = Excel, N/A)
• Thinking Mode: Enabled — the model uses chain-of-thought reasoning before producing the final JSON output
