自建 agent 菜单：Jev 放在模型选择前面做路由
作者把 Jev 放在模型菜单前做实验，便宜问题走 2¢ 档、难题走 Opus 5.5，并逐条展示每次调用成本。
Claude Opus 5.5 went into my AI agent menu at 10¢ a call at once. - Fable 5.1 sits at 20¢ - the Chinese row at 2 to 6¢ - Your deflation chart is my price list. The cache read cut is the number that matters for a bot. Every message re-reads the same system prompt, so cache reads are the fixed cost of every reply. $0.50 to $0.20 is a 60% cut on the one line you can't optimize away. What running your own agent buys you this week ✅ Add the model the day it ships. No waiting for Hermes or OpenClaw to expose it ✅ Show the user what each call costs before they pick. I haven't seen anyone else do this ✅ You route. I put Jev in front of the menu as an experiment cheap questions go to the 2¢ row, hard ones to Opus 5.5. Thinking can't be switched off in 5.5, which is exactly why you don't send it a "gm" ✅ 5.5 follows the writing rules you hand it.
