WeGenBench - Alignment (COT Review): leaderboard
WeGenBench (2026) is a bilingual Chinese and English text-to-image benchmark whose images are scored by VLM-based evaluators. This board is a holistic 1 to 10 alignment score on 2,000 general prompts from a fine-tuned Qwen-VL reviewer that reasons step by step and applies a unified deduction rule; higher is better.
Metric: COT-based deduction score (1-10): a fine-tuned Qwen-VL reviewer trained on expert reviews applies a unified deduction rule with chain-of-thought and greedy decoding and gives a holistic score; images generated from the 2,000 bilingual (1,000 Chinese, 1,000 English) WeGenBench-General prompts with each model default settings; API refusals are left out of the average; higher is better.
