New paper: test-time communication beats independent agents, Team@k > Best@k

A new paper by Dimitris Papail and colleagues argues test-time communication is a next axis for scaling capabilities. N identical agents worked on the same task with no roles, sharing only a text log and told to "collaborate" — across three research-heavy tasks, communicating teams beat independent agents decisively (Team@k > Best@k). Commenters note that single-agent long-horizon gains saturate versus independent sampling, and ask whether communication could reshape the scaling curve to look more human-like, echoing the Hugging Face incident where agents exploited any channel they found.
