Researchers have developed CounterCount, a new framework designed to diagnose counting biases in Vision-Language Models (VLMs). The framework uses paired factual and counterfactual images to test whether VLMs rely on visual evidence or learned priors when object counts differ from typical knowledge. Evaluations revealed that current VLMs perform well on factual images but struggle with counterfactual changes, indicating a reliance on object-level priors even when visual evidence contradicts them. CounterCount also showed that models underweight attention to count-relevant visual tokens, and proposed an attention modulation strategy to improve accuracy. AI
