Seeing Isn't Knowing: Do VLMs Know When Not to Answer Spatial Questions (and Why)?

Researchers reveal that vision-language models (VLMs) fail to recognize when spatial questions cannot be reliably answered due to occlusion or perspective ambiguity, instead producing overconfident incorrect responses. The study introduces SpatialUncertain, a benchmark showing that current VLMs achieve only 30% accuracy under occlusion and below 10% under perspective challenges, highlighting a critical gap between answer correctness and epistemic awareness.

PassiveQA: A Three-Action Framework for Epistemically Calibrated Question Answering via Supervised Finetuning

Researchers propose PassiveQA, a new AI framework that teaches language models to recognize when they don't have enough information to answer questions, choosing to ask for clarification or abstain rather than hallucinate responses. The three-action system (Answer, Ask, Abstain) uses supervised fine-tuning to align model behavior with information sufficiency, showing significant improvements in reducing hallucinations.
