Two new research papers highlight limitations in current vision-language models (VLMs), particularly concerning their ability to retain knowledge after fine-tuning and their lack of "agency" in visual reasoning. The first paper, "Does VLA Even Know the Basics?", introduces Act2Answer, a protocol to evaluate embodied VLA models by having them select answers through actions, revealing that while they perform well on simple concepts, they struggle with richer semantic categories compared to their source VLMs. The second paper, "Position: The Systemic Lack of Agency in Visual Reasoning", argues that VLMs are constrained by a lack of agency, leading them to act as passive semantic retrievers rather than active explorers of visual information, a gap addressed by their proposed Visual Implicit Reasoning Diagnosing Benchmark (V-IRD).
