Researchers have developed a new method called Token Activation Map (TAM) to understand the visual reasoning behind how Multimodal Large Language Models (MLLMs) describe artworks. TAM generates heatmaps that highlight the specific visual evidence a model uses for each generated token, helping to distinguish between visual grounding and reliance on textual priors. The study found that the degree of visual grounding varies significantly based on the semantic category of the token, with MLLMs showing higher accuracy in artist attribution than in predicting artwork titles.
