用 Agent Skills 让 Claude Haiku 替代 Opus 5.5，快 7 倍省一半 token
精选理由
教你不改模型就能让 Haiku 干 Opus 5.5 的活：59 秒替代 7 分钟，token 省一半，思路挺实用。
作者用 Zep Agent Skills 教 Claude Haiku 完成原本由 Opus 5.5 承担的任务，方式类似微调但不需要改动模型本身。效果上，同一任务 Opus 5.5 耗时 7 分钟、消耗 140 万 token，Haiku 只需 59 秒和 70 万 token，速度提升 7 倍、token 消耗减半。文章思路是把大模型的任务经验封装成技能，交给小模型执行以降低成本。

How to replace a large, expensive, and slow model with a small, cheaper, fast model and still get the same results.
7x faster and 50% fewer tokens.
This is like fine-tuning, but without touching the model.
Here, we teach Haiku, using Zep Agent Skills, to do what Opus 5.5 does to complete a task.
• It takes 7 minutes with Opus 5.5. Only 59 seconds with Haiku. • It takes 1.4M tokens with Opus 5.5. Only 700K with Haiku.
