<p dir="auto">帮朋友的小团队做 AI 集成方案，仔细算了一笔 API 成本账，结果出乎意料。</p>
<h2>基础价格对比</h2>

</table>
<p dir="auto"><strong>关键发现</strong>：Claude 的 Prompt Caching 折扣高达 90%，OpenAI 只给 50%。</p>
<h2>真实场景成本计算</h2>
<h3>场景一：客服聊天机器人（日均 500 次对话）</h3>
<p dir="auto">每次对话约 1000 input + 500 output tokens。</p>
<table class="table table-bordered table-striped">
<thead>
<tr>
<th>模型</th>
<th>input成本/天</th>
<th>output成本/天</th>
<th>日成本</th>
<th>月成本</th>
</tr>
</thead>
<tbody>
<tr>
<td>GPT-5-mini</td>
<td>$0.08</td>
<td>$0.15</td>
<td>$0.23</td>
<td>$6.90</td>
</tr>
<tr>
<td>GPT-5</td>
<td>$1.50</td>
<td>$3.00</td>
<td>$4.50</td>
<td>$135</td>
</tr>
<tr>
<td>Claude Haiku</td>
<td>$0.13</td>
<td>$0.31</td>
<td>$0.44</td>
<td>$13.20</td>
</tr>
<tr>
<td>Claude Sonnet (with caching)</td>
<td>$0.15</td>
<td>$3.75</td>
<td>$3.90</td>
<td>$117</td>
</tr>
</tbody>
</table>
<p dir="auto"><strong>结论</strong>：客服场景 GPT-5-mini 最便宜，但有缓存时 Claude Haiku 也不错。</p>
<hr />
<h3>场景二：代码审查辅助（日均 50 次审查）</h3>
<p dir="auto">每次审查约 5000 input + 2000 output tokens。</p>
<table class="table table-bordered table-striped">
<thead>
<tr>
<th>模型</th>
<th>日成本(无缓存)</th>
<th>日成本(有缓存)</th>
<th>月成本(有缓存)</th>
</tr>
</thead>
<tbody>
<tr>
<td>GPT-5</td>
<td>$0.75 + $1.20 = $1.95</td>
<td>$0.38 + $1.20 = $1.58</td>
<td>$47.40</td>
</tr>
<tr>
<td>Claude Sonnet</td>
<td>$0.75 + $1.50 = $2.25</td>
<td>$0.075 + $1.50 = $1.58</td>
<td>$47.40</td>
</tr>
<tr>
<td>Claude Opus</td>
<td>$3.75 + $7.50 = $11.25</td>
<td>$0.38 + $7.50 = $7.88</td>
<td>$236.40</td>
</tr>
</tbody>
</table>
<p dir="auto"><strong>结论</strong>：有 Prompt Caching 时 GPT-5 和 Claude Sonnet 成本几乎持平。Opus 贵 5 倍。</p>
<hr />
<h3>场景三：文档 RAG 问答（日均 1000 次查询）</h3>
<p dir="auto">假设 10 个常见文档缓存后，每次查询只需 500 tokens output。</p>
<table class="table table-bordered table-striped">
<thead>
<tr>
<th>模型</th>
<th>日成本(有缓存)</th>
<th>月成本</th>
</tr>

<tbody>
<tr>
<td>GPT-5-mini</td>
<td>$0.30</td>
<td>$9.00</td>
</tr>
<tr>
<td>GPT-5</td>
<td>$6.00</td>
<td>$180</td>
</tr>
<tr>
<td>Claude Sonnet</td>
<td>$0.75 (缓存 90% off)</td>
<td>$22.50</td>
</tr>
</tbody>
</table>
<p dir="auto"><strong>惊喜</strong>：在 RAG 场景中，Claude Sonnet 的成本竟然接近 GPT-5-mini 的水平，因为 90% 的 caching 折扣太猛了。</p>
<hr />
<h2>年度成本对比（中等使用场景）</h2>
<p dir="auto">假设日均调用 1M tokens（input）+ 0.5M tokens（output）：</p>
<table class="table table-bordered table-striped">
<thead>
<tr>
<th>方案</th>
<th>月成本</th>
<th>年成本</th>
</tr>

<tbody>
<tr>
<td>只用 GPT-5-mini</td>
<td>~$150</td>
<td>$1,800</td>

<td>GPT-5 (有缓存)</td>
<td>~$300</td>
<td>$3,600</td>

<tr>
<td>Claude Sonnet (有缓存)</td>

<tr>
<td>Claude Sonnet (无缓存)</td>
<td>~$630</td>
<td>$7,560</td>
</tr>
<tr>
<td>混合方案*</td>
<td>~$180</td>
<td>$2,160</td>
</tr>
</tbody>
</table>
<p dir="auto">*混合方案：80% GPT-5-mini + 20% Claude Sonnet (高难度任务).</p>
<hr />
<h2>终极省钱策略</h2>
<ol>
<li><strong>分层调用</strong>：简单任务用 mini → 省 90%；复杂任务用 Sonnet/Opus</li>
<li><strong>开启 Prompt Caching</strong>：Claude 的 90% 折扣是杀手锏</li>
<li><strong>System Prompt 复用</strong>：将共用指令放在 System Prompt 中，最大化缓存命中率</li>
<li><strong>监控用量</strong>：用 OpenAI Playground 和 Anthropic Console 的 Usage 页面监控每日消耗</li>
</ol>
