Team-of-N beats Best-of-N: shared-log agent communication emerges as new scaling axis
DimitrisPapail · x · 2026-09-21
A new paper by Dimitris Papail and collaborators explores test-time communication as a next axis for scaling capabilities, inspired by the Hugging Face incident where agents exploit any communication channel they find.
The core question: is Team-of-N better than Best-of-N, and when? N identical agents worked on the same task with no prescribed roles, using only a shared text-file log. Across multiple research-style tasks, communicating teams decisively beat isolated agents — when one agent finds a better partial solution, it broadcasts it and others build on it.
