OpenAI Dev DayでCodexチームのエンジニアが実際のワークフローを披露してたんだけど、これ見てAI時代の開発の型が完全に見えた。結論から言うと、テスト駆動開発とドキュメント整備、この2つを徹底的にやる。

Codex on the left building me a Polymarket scanner Claude Code on the right building me a crypto whale scanner ChatGPT5 desktop app in the middle ideating what to build next 1 person. 3 AI agents working. This is how you build a 1 person billion dollar business

OpenAI's Codex is my new favourite 😩

cursor vs codex no I won't explain

OpenAIが公開した「GPT-5 Codex用プロンプトガイド」が有益。 ㅤ ㅤ AIの性能を最大限にするテクニックを網羅： ㅤ ㅤ スレッドにまとめていきます👇🧵

Codex Meetup Japan #1 が19時から始まりますよー。 Codex、Codex CLIは個人的にも熱いAIツールなので、時間がある人はオンラインでも参加すると良いと思います！ https://t.co/AFUbdMl1ug #AI駆動開発

India has erected barricades to stop indians thowing rubbish in the Yamuna River. This doesn't bother indians, they just toss their trash on the roads instead! For indians the entire world is a toilet and a trash can.

Claude and Codex are really good at using fastmod/sg (ast-grep), but they don't know that they can. But if you tell them that they can and should use it, they will!

自分の開発の仕方に以下に無駄が多かったか Codexチームによる開発のやり方講座有益すぎ

Codex is so good, and is going to get so amazing. I am having a hard time imagining what creating software at the end of 2026 is going to look like.

【保存版】OpenAIのエンジニアがDevDayで語った開発を10倍速にするCodeXの使い方 約30分の動画を日本語で要点をまとめたので是非 ○note https://t.co/J0QtLrj6Jd 《詳細要約》 ■ 意外な発見 1. 独自用語が効く ・「Exec Plan」など独自の用語を使うとCodexが特別概念として認識 ∟

OpenAIのエンジニアたちが、実際にCodexを使ってどうやって開発しているかを紹介した動画がある（スレッドに）。

So, basically when working on frontend only use Claude 4.5. Backend, refactoring, logic issues, Codex-High. Hope this helps!

OpenAI's Codex might be the most underrated AI tool ever It allows you to spin up an ARMY of AI agents that build apps for you in the cloud ANYONE can build now, even if you've never coded a day in your life Watch this video to learn 5 tricks for getting started:

The Indian mindset is one of constant scams and fraud. This is why indian is a third world country. Little things like jumping the gates, not paying for train tickets, littering, scamming etc turn into systemic issues when done by over 1.5 billion people.

Me, Codex, Cursor and Claude Code, building a screen recording app together 😂😂

max版 上周四刚恢复的 然后其中周五周六我还没咋用 而且我还同时在跑codex.... 就又防沉迷了 太难了，三个AI又罢工了这个
