New paper shows test-time communication makes agent teams crush independent parallel attempts
DimitrisPapail · x · 2026-09-22
- Core question: when does communication make a group of agents MORE capable than the same agents working alone — Team-of-N vs Best-of-N?
- Setup: N identical agents, no prescribed roles, only a shared log (text file), told to "collaborate", tested across three "researchy" tasks.
- Result: communicating teams beat independent parallel agents decisively — sharing a breakthrough pushes the whole group forward, which the authors frame as another argument for open collaborative research.
- They link this to the HF incident: agents will exploit any communication channel they find, making test-time communication a new axis for scaling capabilities.
