## Reach
- followers: 10462
- posts_observed: 1
- verified: true
- size_tier: koc

## Engagement
- status: peak_post_only
- peak_post_engagement_rate: 0.00057
- best_post_interactions: 6
- measurement_source: threads_post_likes
- measurement_formula: likes on one post (Threads exposes no reply or repost count on this path)
- comparable_pool: peak_interactions
- status_note: We have only the single best observed post, so no mean exists. peak_post_engagement_rate is an UPPER BOUND, systematically higher than an average — never compare it against an average rate.
- unit_note: engagement_rate and peak_post_engagement_rate are ratios (0-1); avg_interactions_per_post and best_post_interactions are absolute counts. Read status before reading any number: a null rate has several different causes and status says which one applies here.

## Evidence
- [threads_krumjahn#43ccab9c] 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。 (https://www.threads.com/@krumjahn/post/DacTgB9m7cf)
- [threads_krumjahn#67db75bf] 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。 ---
- [threads_krumjahn#2551e3b7] 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？
- [threads_krumjahn#88603b88] 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 試試——省的不只是預算，是整條流程。
- [threads_krumjahn#c4d1a259] 一個工程師開源了個 AI landing page design skill，用的人直接省掉 80% 調參時間。 它不是範本，是一套能理解你設計邏輯的結構。 AI 設計工具產出 slop 的最大原因，是你給的 skill
