Paper Reveals VLMs Answer Without Images, Multimodal Scores Inflated

In the "Mirage Probes" paper, researcher zivravid found that Vision Language Models (VLMs) can correctly answer image-based questions even without an attached image. This "hallucination mirror" effect (Asadi et al.) causes multimodal benchmark scores to be systematically inflated. The paper explores the mechanism behind this phenomenon, highlighting potential biases in current multimodal evaluation systems and offering insights for more accurately assessing true visual understanding.
