What this article says

作者把同一组 10 个 agent 任务分别放到 GPT-6 Astra 和 DeepSeek V4.1 Flash 上跑,按 token 单价逐项算出日成本:Astra 约 13.15 美元,DeepSeek 约 0.36 美元,差距接近 36 倍。文章的核心主张不是「换便宜模型」,而是分层路由:把简单、高频、容错高的步骤(分类、抽取、格式化、初筛)交给便宜模型,只在需要长链推理、复杂工具调用或高风险决策的环节调用 Astra。作者称按这套路由配置,总账单可下降约 59%,同时最难的那部分工作仍由强模型完成。结论是成本优化的关键在任务切分与路由策略,而不是单纯比单价或一刀切换模型。

$13.15 a day on GPT-6 Astra. $0.36 a day on DeepSeek V4.1 Flash.

Same 10 agent jobs, priced token by token.

Here's the routing setup that cuts the bill 59% without handing your hardest work to the cheap model. https://x.com/i/article/2100114974123413504
