## AI 摘要

CF-World是一个反事实基准，用于测试文本到图像（T2I）模型在系统性违背现实世界先验规则下生成图像的能力。每个场景分三个递进层级：事实生成、显式反事实生成和隐式反事实生成。评估采用VLM-based评估器CF-Eval，引入两个指标：Prior Resistance Rate（PRR）衡量克服固有先验的能力，Reasoning Retention Rate（RRR）评估无显式视觉线索时的推理依赖生成。实验表明，所有模型在反事实场景中性能急剧下降，原因是T2I模型将世界知识与视觉外观编码为紧密耦合模式，过度依赖训练数据中的频繁视觉共现，在反事实任务中退回至熟悉常识先验。

Text-to-image (T2I) generation models have achieved remarkable progress in producing visually realistic images from natural language prompts. Yet it remains unclear whether their success reflects genuine causal understanding or sophisticated pattern matching over visual-textual correlations. Inspired by Russell's inductivist turkey, we introduce Counterfactual-World (CF-World), a counterfactual benchmark designed to investigate whether text-to-image models can generate images under rules that systematically contradict real-world priors. CF-World organizes each scenario into three progressive levels: factual generation under ordinary world knowledge, explicit counterfactual generation with direct visual instructions, and implicit counterfactual generation requiring causal deduction from altered rules. We evaluate both open-source and closed-source T2I models using a Vision Language Model (VLM)-based evaluator (CF-Eval). Furthermore, we introduce two metrics: Prior Resistance Rate (PRR), which measures a model's ability to overcome entrenched real-world priors, and Reasoning Retention Rate (RRR), which assesses whether models can maintain reasoning-dependent counterfactual generation without explicit visual cues. Experiments show that all models exhibit sharp degradation from factual to counterfactual settings. Further analyses suggest that these failures arise because current T2I models encode world knowledge and visual appearances as tightly coupled patterns. Consequently, their heavy reliance on frequent visual co-occurrences within the training data forces them to default to familiar commonsense priors when tasked with rendering counterfactual worlds.
