Seeing without Looking: Do Vision-Language Benchmarks Really Test Vision?
📰 ArXiv cs.AI
Vision-language benchmarks may not accurately test visual understanding, and models may rely on language cues instead of visual evidence, which is crucial for developing reliable VLMs
Action Steps
- Investigate the performance of VLMs on benchmarks with reduced image tokens to assess their reliance on visual evidence
- Analyze the correlation between benchmark accuracy and visual understanding in VLMs
- Develop new benchmarks that specifically test visual understanding, such as those that require models to identify objects or scenes without language cues
- Evaluate the effectiveness of existing VLMs in real-world applications where visual understanding is critical
- Compare the performance of VLMs with and without visual evidence to identify areas for improvement

Title: Seeing without Looking: Do Vision-Language Benchmarks Really Test Vision?
Abstract:
arXiv:2605.22903v1 Announce Type: cross Abstract: Benchmark accuracy is often implicitly assumed to reflect grounded visual understanding in vision-language models (VLMs), yet it remains unclear to what extent such scores truly reflect reliance on visual evidence. Motivated by a surprising observation that removing a substantial fraction of image tokens only degrades model performance very slightly on a widely used hallucination benchmark, we systematically investigate this mismatch in a set of
