Evaluation of GPT-4o and GPT-4o-mini's Vision Capabilities for Compositional Analysis from Dried Solution Drops
- 用GPT-4o分析12种盐的干燥沉积图像，每种200张。
- 模型正确识别57%的盐类，显著高于随机水平。
- 展示通用AI可可靠识别盐类，适合材料分析场景。
当微升量级的盐溶液在非多孔表面干燥时，会形成受复杂结晶动力学和流体运动影响的不规则但具有特征性的沉积图案。本研究利用OpenAI的图像语言模型，分析了12种盐类、每种200张图像的数据集。GPT-4o在盐类分类任务中准确率达57%，显著优于随机猜测水平，且表现优于GPT-4o mini。结果表明，通用人工智能工具在从干燥图案中可靠识别盐类方面具有潜力。
原文摘要 · Abstract (English)
When microliter drops of salt solutions dry on non-porous surfaces, they form erratic yet characteristic deposit patterns influenced by complex crystallization dynamics and fluid motion. Using OpenAI's image-enabled language models, we analyzed deposits from 12 salts with 200 images per salt and per model. GPT-4o classified 57% of the salts accurately, significantly outperforming random chance and GPT-4o mini. This study underscores the promise of general-use AI tools for reliably identifying salts from their drying patterns.
