AI代理团队消耗大量token却只带来微小质量提升
研究发现AI代理团队成本是单个代理的1.8倍至5.1倍，但质量提升却非常有限。这将影响使用AI执行任务的公司。
vals ai tested gpt-6 sol and claude opus 5.5 on the vibe code bench in solo and team setups at two reasoning levels. teams cost 1.8x to 5.1x more than single agents but only showed a statistically significant improvement in one case: gpt-6 sol at medium reasoning with a 7.3 point higher score. anthropic's own tests with opus 5.5 showed similar results. openai researcher noam brown noted that multi-agent systems mainly buy speed, not better quality. this affects companies using ai for tasks and may signal a need to reevaluate the use of agent teams.
