多智能体陷阱的根本原因：状态分歧与协调税
</h3>
<div class="content">
<div class="law-item">
<span class="law-title">协调成本爆炸：</span>单个智能体任务成本$0.10，多智能体系统可能需要$1.50

三大崩溃定律
</h3>
<div class="content">
<div class="law-item">
<span class="law-title">定律1：工具协调权衡</span>
在固定计算预算下，工具密集型任务会因多智能体协调开销而受到不成比例的影响。协调token与推理token直接竞争有限的上下文窗口。
</div>
<div class="law-item">
<span class="law-title">定律2：能力饱和定律("45%规则")</span>
当单智能体基线超过约<span class="highlight">45%</span>阈值时，协调会产生递减或负回报(β=-0.408)。弱智能体的幻觉通过通信渠道传播，污染集体智能。
</div>
<div class="law-item">
<span class="law-title">定律3：架构依赖的错误放大</span>
独立智能体通过不受控制的传播将错误放大<span class="highlight">17.2倍</span>，而集中式协调将错误放大控制在<span class="highlight">4.4倍</span>。
