Third-party test of MolmoAct 2: color-sensitive VLA that still struggles with small-object grasping
YuXiang_IRVL · x · 2026-09-03
The IRVL team ran MolmoAct 2 on their VLA-Replica benchmark setup and shared one successful case. They put "zero-shot" in quotes since the model's training data is unknown.
Preliminary observations:
- The model is quite sensitive to object color; detailed color instructions help performance.
- It struggles with precisely grasping small objects such as blocks.
