CollabBench CWAH - Helpfulness: leaderboard
Affective collaboration quality in the CWAH-MultiPlayer household game of CollabBench (2026): helpfulness (task focus, proactive support and useful coordination) of the evaluated agent, scored by a penalty-based LLM judge over windows of its reasoning, messages and actions, out of 5. Higher is better. The evaluated model plays one seat of a two-player game with a simulated partner whose personality varies.
Metric: Helpfulness score (out of 5): helpfulness (task focus, proactive support and useful coordination), rated by a penalty-based DeepSeek-V3.1 judge: each window of three consecutive agent actions starts at 5 and loses 1 to 3 points per violation, and the trajectory score subtracts violation and worst-window terms and a message-sparsity penalty, clipped at 0; 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; higher is better.
