Just launched two major updates for ChatGPT app builders: 👨‍💻 What makes a great ChatGPT app — a new guide on capability selection and conversation- & discovery-first design. 🧩 New Apps SDK UI component library — ChatGPT-native building blocks to help teams move faster on UI. 👉 developers.openai.com/blog/what-make… 👉 openai.github.io/apps-sdk-ui/ #ChatGPT #DevTools #AppSDK

Subagents are now available in Codex. You can accelerate your workflow by spinning up specialized agents to: • Keep your main context window clean • Tackle different parts of a task in parallel • Steer individual agents as work unfolds

NYC devs, excited to be in town for a few events!

Codex is going global. Our Codex ambassadors are running meetups around the world so you can: • Join hands-on Codex workshops • Share real world workflows • Ship projects with your local community

all good things in life start with c claude cursor celsius canada

Codex themes are live. 🎨 Productivity gains: TBD. Vibes gains: immediate.

@andrewlee07 @rohanvarma @dkundel You can have an automation in the codex app, to pull in GH comments, and kick off tasks to complete them

@rohanvarma @dkundel Is there a way for codex to auto fix the issues from the reviews?

If you want AI Code Review, but don't want to pay $25 per review (not a typo), check out Codex Review! It leverages frontier Codex models, finds complex issues, and 100% usage based. Most runs should cost ~$1 or less developers.openai.com/codex/integrat…

@chongdashu Nice work 👏 🎮

Some experiments with using Codex to generate GAME READY pixel art assets → Codex CLI → GPT 5.4 → GPT Image 1.5 1. Create design mock up 2. GPT 5.4 to create art guide 3. Create high-res character then downscale 4. GPT 5.4 to animate pixels 5. PhaserJs for test scene Funny enough, Codex complained that Image 1.5 was not able to do precise pixel edits, so it did it by hand. Going to experiment more.

@Dimillian @OpenAI @romainhuet Welcome Thomas 💻 !

I'm joining @OpenAI at the end of the month, and I can't wait to get started! I'll be working on everything related to Codex, bringing what I learned building Codex Monitor, and working with the developer experience team with @romainhuet!

New post on the OpenAI Developer Blog: how we use skills for open-source maintenance, from planning and coding to testing and release-readiness checks with GitHub Actions. Hope it's useful for your projects too 🙌 developers.openai.com/blog/skills-ag…

@threejs Love it. Three.js demo incoming.

Made with Three.js 👌

@jxnlco Always be applying. This is the way.

I just applied for an apartment in Hayes valley. Please pray for me

@kuizinas @OpenAI For more info on image gen api here is: developers.openai.com/api/docs/guide…

@coreyching @OpenAI This looks cool. I want to build something like this too. Where do the image assets come from though?

Built a tactical turn-based RPG with Codex + GPT-5.4, using Playwright for testing and image-gen for the visuals. I grew up loving turn-based RPGs, so this was a fun one to build. Sharing a 45s demo below — it’s also featured in the @OpenAI GPT-5.4 blog post for anyone who wants more context. openai.com/index/introduc…

@kuizinas @OpenAI images created with our image-gen skill, which hits the openai image-gen api.

@hirohasusan ありがとう🙏🏼 @seratch can help provide more info

Ccdex + GPT-5.4でSRPGを作った例、画像も全てAIで生成 普段Codex使ってる人は「まあこのくらいなら作れるでしょうね」っていう感覚じゃないかな、今のCodexはそれくらい優秀

@PaulSolt @dkundel @OpenAI Thanks! Check out the new playwright skill for FE testing

@coreyching @dkundel @OpenAI Nice demo!!!

@wonforall @OpenAI Welcome Won ⚡️

hi x — i'm won. i'm a cmu new grad that recently joined @OpenAI to work on codex. i started out as a non-technical creative with more ideas than ways to build them. learning to code in college drastically changed how i thought about what people can create. since then, my north star has been a world where tinkerers can materialize their ideas without needing a technical background. i believe codex will lead us to that world as the foundation, and i'm excited to do my part to push it forward—thanks to @thsottiaux and @ah20im for the conviction on the direction! i will be posting about codex, thoughts/perspectives on related matters, and more. time to 🏃‍♂️

@georgehanu @OpenAIDevs I had the mechanics in mind, but you can definitely have the model suggest gameplay options to implement

@OpenAIDevs AI generating code while Playwright stress tests the UI sounds like a fun dev loop ⚙️ Did GPT help design mechanics too or mostly implementation?

Developers 🤝 GPT-5.4 computer use + coding capabilities Here’s a browser game built using the Playwright skill in Codex for playtesting and iteration: x.com/coreyching/sta…

@openGPUnetwork @OpenAI Taste, and creativity definitely is the edge here. Also the most fun part of building.

@coreyching @OpenAI Playwright for playtesting is the quiet highlight here The AI builds the game and tests it itself, while you step in mainly to judge whether it’s actually fun At that point, the human role is mostly creative taste and that’s arguably the most enjoyable part anyway

We shipped a new showcase site for builders to see the magic of what you can build with Codex. Submit your project to get highlighted!
