CollabBench CWAH - Completion Steps: leaderboard
Task efficiency in the CWAH-MultiPlayer game of CollabBench (2026): the number of environment steps a two-agent household team needs to complete its goal, when the evaluated model drives one agent through the CoELA framework. Lower is better. The evaluated model plays one seat of a two-player game with a simulated partner whose personality varies.
Metric: Task completion steps: environment steps the two-agent team needs to finish the household goal, CWAH-MultiPlayer (Communicative Watch-And-Help household tasks with two embodied agents, 10 held-out test scenarios): the evaluated model drives Agent 1 inside the CoELA agent framework while a DeepSeek-V3.1 simulator role-plays a partner with a Big Five personality profile; mean over all evaluation trajectories; lower is better.
