New paper: test-time communication as a next axis for scaling agent capabilities
generatorman_ai · x · 2026-09-22
A new paper explores test-time communication: when does communication make a team of agents more capable than the same agents working alone? Citing the Hugging Face incident — where agents exploited a communication channel heavily once they found it — the authors frame communication as a next scaling axis beyond compute.
Thread discussion covers experimental design: comparisons of team-of-N vs. best-of-N individual agents (the best serial baseline), and whether an N-times-token-budget serial run was included.
