我在開一個 4 堂的 AI 系列課，昨天是第一堂。40+ 人，課後大家不想走。 但真相是：前一晚我把投影片給我老婆（老師）看，她只說「很爛」。我修到凌晨 2 點。 我沒教工具/神 prompt，我教的是原理：怎麼思考 AI、怎麼把目標拆成可協作步驟、怎麼迭代“教”AI 變懂你。 最爽的是：最後大家有自信——工具換了也能達成目標。

Microsoft 悄悄放棄 OpenAI，自己造了 7 個 AI 模型。 CEO Mustafa Suleiman 在 Build 2026 親自發表。 可以在 PowerPoint 裡生圖、用 43 種語言轉錄音訊、直接在 OneDrive 跑。 不是買來的，是自己訓練的。 以後 Microsoft 全家桶用 AI，不用再繞去 OpenAI 了。 ---

我今年砍掉了第三個付費訂閱。 前兩個是 Canva 和 Granola。這次是我的影片編輯 app。 我沒有換更便宜的工具——我叫我的兩個實習生直接做一個。 幾天，用 Fable 5，就做出一個比我付錢的還好用的編輯器。只做我需要的那一件事，一次輸出，不用再匯出兩次。 這支影片，就是用他們做的工具剪的。 半年前我會說這不可能。現在，兩個實習生就能做出我以前每個月付錢租的軟體。 你最想砍掉哪一個訂閱？

有人用 Codex 的 ImageGen 模組加 img2threejs， 一個指令就把 2D 圖轉成互動 3D low-poly 物件。 一張圖才用掉 8 個 token——成本是 Blender 工作流的 1/100。 上線 24 小時內被 fork 超過 6000 次。 不用開 Blender，不用寫 Three.js，不用找設計師。 兩個模組疊在一起，工作流就變了。 下次外包 3D 素材前，先丟給 Codex…

This is a position, not a verdict. A percentile says where this account falls among comparable accounts on signals we can measure — it does not say this creator is a better fit for your campaign. We ran a blind benchmark and measured no reliable advantage in selection quality, and do not claim one.
