Researchers are investigating limitations in vision-language models (VLMs), particularly their tendency to hallucinate and struggle with causal reasoning. One study identifies a geometric over-alignment between visual and text embeddings as a root cause for hallucinations, proposing methods to mitigate this bias. Another paper introduces new benchmarks, VQA-Causal and VCR-Causal, to specifically test causal order reasoning in VLMs, revealing significant performance gaps and suggesting that a lack of explicit causal expressions in training data contributes to these deficiencies.
