Anthropic 發現單個 AI 代理在質量和速度上優於多個子代理
anthropic 建議將子代理合併為單個代理，以便按需加載上下文，從而在質量、成本和延遲方面取得更好的結果。這將影響使用多代理設置的公司。
anthropic recommends that companies evaluate consolidating sub-agents into a single agent that loads context on demand. the company's experience shows that many specialized sub-agents can lead to higher latency, rising costs, and information loss at every handoff. anthropic's applied ai team found that a single agent using skills frequently beat both monolithic prompt designs and sub-agent setups on quality. newer models like opus 4.5, opus 5.5, and fable 5.1 can manage complex plans directly in a single loop, reducing costs and wait times. anthropic has published a migration kit on github to help teams make the transition.
