  This paper explores the image synthesis capabilities of GPT-4, a leading
multi-modal large language model. We establish a benchmark for evaluating the
fidelity of texture features in images generated by GPT-4, comprising manually
painted pictures and their AI-generated counterparts. The contributions of this
study are threefold: First, we provide an in-depth analysis of the fidelity of
image synthesis features based on GPT-4, marking the first such study on this
state-of-the-art model. Second, the quantitative and qualitative experiments
fully reveals the limitations of the GPT-4 model in image synthesis. Third, we
have compiled a unique benchmark of manual drawings and corresponding
GPT-4-generated images, introducing a new task to advance fidelity research in
AI-generated content (AIGC). The dataset is available at:
