DO AGENT TEAMS PAY OFF? A CASE STUDY ON VIBE CODE BENCH

Summary from the TLDR AI newsletter

Researchers ran tests on GPT-6 Sol and Claude Opus 5.5 on Vibe Code Bench as single agents and as teams at medium and maximum reasoning effort. Teams cost 1.8 to 5.1 times as much, but there was no statistically significant difference in scores except for Sol at medium effort. Whether a team was worth it depended on the model, task, and budget. Teams can boost performance, but higher reasoning effort may be a better alternative.
