Researchers have developed MoST, a novel testing framework designed to evaluate the modality sensitivity of vision-language models (VLMs). MoST employs a search-based approach to combine image and text perturbations, revealing that some VLMs are more susceptible to textual changes while others are vulnerable across both modalities. The framework's findings indicate that joint perturbations can be more effective than single-modality ones with smaller individual modifications, and human evaluations suggest that while perturbed inputs remain understandable, VLMs still lag behind human accuracy in tasks like object localization.
