A study indicates that AI models like ChatGPT can mimic human sensory associations, particularly in linking shapes and colors to tastes. Conducted by researchers from various institutions, the study found that ChatGPT-4 better aligned with human patterns than ChatGPT-3.5, associating round shapes with sweetness and angular shapes with bitterness. The findings suggest potential applications in marketing and product design, highlighting AI's evolving ability to understand sensory connections through language processing.
