Does VLA Even Know the Basics? Measuring Commonsense and World Knowledge Retention in Vision-Language-Action Models

What happened
This paper introduces the Act2Answer evaluation protocol to measure commonsense and world knowledge retention in Vision-Language-Action (VLA) models. Instead of text-based QA, agents must demonstrate understanding by executing physical actions, revealing how knowledge generalizes across semantic categories.
Why it matters
It highlights a shift toward action-based evaluation rather than text-only benchmarks for complex models.
The take
While focused on physical/embodied AI, the concept of evaluating understanding through action (Act2Answer) is highly relevant for digital agents. We need to move away from static benchmarks to action-based verification.
Do this
Consider adapting the action-as-evaluation paradigm to your digital agents by testing their tool-use accuracy rather than output text.
