WatchAct - Ordinal: leaderboard

The Ordinal task of WatchAct (Li et al., 2026): after watching a real video of a person in a tabletop scene, the robot planner grounds the task in a specified ordinal event (for example the second object the person touched). A vision-language model writes a high-level Pick/Place/Open/Close plan that is executed symbolically in an aligned LIBERO scene; plan success rate in percent over 215 instances, higher is better.

Metric: Plan success rate (%; the VLM's high-level Pick/Place/Open/Close plan, predicted from a real human video and an instruction, run through a symbolic executor and checked against the task's success predicate; 215 instances). Source: arxiv.org. Saturation forecast: Around February 2027. 9 models tracked.
