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/s…

Turns out building with @ChatGPT Sites is pretty addicting. So is clicking cookies. 🍪 I made a little demo that does both, with a database and an MCP server so ChatGPT and Codex can join in. Come hang out. I hope it gives you an idea for something fun to build. Chapters: 00:00 A cookie clicker for humans and AI 00:27 The prompt I started with 00:41 Saving clicks in a database 01:16 Adding MCP tools 01:29 MCP in plain language 02:09 Testing with MCP Inspector 03:11 Asking ChatGPT for the click count 03:40 Clicking a cookie with Codex CLI 04:10 What will you build?

Had a very fun panel chat with @coreyching and Bonnie 😁 The crowd was amazing! #OpenAIDevDayExchange

Thank you so much for joining #OpenAIDevDayExchange Tokyo yesterday! 🗼

Great to be in Tokyo with @gabrielchua and @seratch for OpenAI DevDay Exchange 🇯🇵 Excited to share what we’ve been building with the developer community here! よろしくお願いします！

I’ll be around the Build & Run Agents booth for the next few hours. Come and say hi! #OpenAIDevDay

I missed this comment at the time, but yes...it was resolved within five hours :)

Another OpenAI Agents SDK update: This has been a long-awaited feature! You can now set a timeout for each model call, and the retry mechanism also handles timeouts. See openai.github.io/openai-agen… for details.

I've been running this image generation code example over the past 13 months to track its behavior: github.com/openai/openai-age… The outputs are now dramatically different from what they were back then!

Valibot made it into the OpenAI Agents SDK. 🔥 Thank you for implementing the Standard JSON Schema spec!

OpenAI Agents SDK for TS now supports Standard Schema. This means you can use not only Zod, but also any other schema library compatible with the spec, such as Valibot. See openai.github.io/openai-agen… for details! 👋

Writing tests for agent apps built with the OpenAI Agents SDK is now much easier! You can use the newly added, reusable ScriptedModel utility to mock model calls. See openai.github.io/openai-agen… for details.

Since posting this a week ago, I've continued optimizing the harness to help Codex reach a mergeable state even faster. This really feels like a new era in software engineering.

Sorry this took so long. We received requests for React Native support in the same month that we released OpenAI Agents SDK TS, and it's finally here! Here's a demo app showing how to use the runtime shim: github.com/openai/openai-age…

This repo skill improves my first-pass code (but takes time). If 👍 is hard to earn in GPT-5.6 Sol reviews, try something similar. github.com/openai/openai-age…

Helped enthusiastic Codex users with their Build Week submissions this morning! It’s a public holiday here in Japan, but they were up early building! 🚀🚀🚀

You might have noticed that the multi-agent feature was also released in beta for the Responses API with GPT-5.6 models: developers.openai.com/api/do… It's now supported in our Agents SDKs as well! github.com/openai/openai-age…

I was just thinking back to how tough it was to complete this refactoring work six years ago: github.com/slackapi/python-s… Now that we have Codex, doing something similar in 2026 would be drastically easier. What a great time to be a software developer.

Earlier today, I started managing my hobby OpenClaw setup more easily from mobile, using my personal Codex on the same host

To celebrate the realtime model release, @seratch has updated RealtimeAgent to use gpt-realtime-2 by default in the Agents SDK 📷  (WebRTC & WebSocket): openai.github.io/openai-agen… 📷  (WebSocket): openai.github.io/openai-agen…
