We study idiom-based visual puns--images that align an idiom's literal and figurative meanings--and present an iterative framework that coordinates a large language model (LLM), a text-to-image model (T2IM), and a multimodal LLM (MLLM) for automatic generation and evaluation. Given an idiom, the system iteratively (i) generates detailed visual prompts, (ii) synthesizes an image, (iii) infers the idiom from the image, and (iv) refines the prompt until recognition succeeds or a step limit is reached. Using 1,000 idioms as inputs, we synthesize a corresponding dataset of visual pun images with paired prompts, enabling benchmarking of both generation and understanding. Experiments across 10 LLMs, 10 MLLMs, and one T2IM (Qwen-Image) show that MLLM choice is the primary performance driver: GPT achieves the highest accuracies, Gemini follows, and the best open-source MLLM (Gemma) is competitive with some closed models. On the LLM side, Claude attains the strongest average performance for prompt generation.

This paper introduces VisualQuest, a novel image dataset designed to assess the ability of large language models (LLMs) to interpret non-traditional, stylized imagery. Unlike conventional photographic benchmarks, VisualQuest challenges models with images that incorporate abstract, symbolic, and metaphorical elements, requiring the integration of domain-specific knowledge and advanced reasoning. The dataset was meticulously curated through multiple stages of filtering, annotation, and standardization to ensure high quality and diversity. Our evaluations using several state-of-the-art multimodal LLMs reveal significant performance variations that underscore the importance of both factual background knowledge and inferential capabilities in visual recognition tasks. VisualQuest thus provides a robust and comprehensive benchmark for advancing research in multimodal reasoning and model architecture design.
