Reason

The paper explicitly proposes a World Action Model for action-conditioned world modeling and action prediction in robotics/control settings.

Evidence

• uses optical flow as action representation for World Action Models
• supports policy mode for action prediction and world-model mode for future video generation guided by target flow
• evaluated on RoboTwin manipulation and WorldArena world modeling

Taxonomy Evidence

• dual-stream diffusion framework
• jointly modeling flow videos and RGB videos within a shared pretrained video generator
• policy mode generates flow for action prediction
• world-model mode uses target flow sequences to guide future video generation
