OpenAI Developers is OpenAI's official channel for developers, sharing APIs, tools and examples. Recent coverage focused on weekly Agents API updates such as Auto Review, computer use and Bedrock managed agents, 12-hour prompt caching in the API, Codex voice workflows and a community hardware projects site, plus Sites reaching general availability for Enterprise and new ChatGPT plugin extensions.
Building with the Agents API? Here's what we shipped this week for you: [Quoting @stevendcoffey]: 🗣️ The Agents API team has a shipping problem – we literally cannot stop. Here’s what we cooked up for you beautiful people this week: 💂 Auto Review: Just like…
Meet @Scav, who brings builders together in a shared robotics community where they push the edges on what's possible with AI in the physical world. In one experiment, GPT-6 Astra remotely controlled a robot arm:
You can now choose 12-hour prompt caching in the API. Persistent agents, like dots, reuse context throughout the day. You can keep shared instructions, tools, and context cached longer and pay the lower cached-input rate, even when requests are hours apart.
COOKED: Ep. 1 🧑🍳
What have you been cooking with Codex?
Looking for a weekend project? Here’s what the community has been building and how you can replicate it yourself:
Put your dot on call. Ali, an engineer at OpenAI, used his dot to triage an on-call incident at 3am. His dot investigated the issue and started a Codex thread, so he could steer the work from his phone in the ChatGPT app.
You can just build things with Codex We built a site for you to explore hardware projects from the community and share your own.
Sites is now generally available for Enterprise, with US and EU data residency for new Sites in eligible workspaces. Build team apps with databases and authentication. @kagigz shows how to schedule updates and let teammates use their own connected data with P…
Build richer, more interactive plugins for ChatGPT. With plugin extensions, you can launch plugins from the sidebar, support @ mentions, and add file viewers. See how in this walkthrough with @coreyching:
Talk to Codex and give your keyboard a break: [Quoting @codestantine]: I used to sit at my desk all day. Now I send off presentations from my sunroom using voice. ☀️
Building with the Agents API? Catch up on what’s new: [Quoting @stevendcoffey]: The team behind Agents API continues to cook. Here's what's new this week: Computer use: Spin up a browser + agent with 1 API call 🖥️ Bedrock Managed Agents: Agents API except AW…
Your dot learns how you work, keeps context across apps, coordinates Codex tasks, and flags what needs your attention. [Quoting @dkundel]: Saw some asks about whether you should use dots or Codex. In reality they work great together! My dot is now my favorite…
Heard you liked the @modretro Chromatic. So we added one to the side quest. You have 48 more hours to join. [Quoting @OpenAIDevs]: Ready for a DevDay side quest? 10 builder challenges. 5 Codex Micros up for grabs. Complete any 5 side quests to earn 1 raffle t…
From an idea to a game you can play on @modretro. We caught up with @Casey to talk about the future of creativity:
dots demo. Now... with better WiFi.
Shareable profiles bring your Sites and plugins together in ChatGPT, so others can find and reuse what you’ve made. Built it? Show it off.
We saved you a seat. See you tomorrow for the OpenAI DevDay keynote:
Meet the winners of The WebMCP Challenge. These 10 projects show what people and agents can build together when websites expose structured tools agents can use. 🧵 See the winning projects and the builders behind them:
OpenAI DevDay roll call Where are you joining us from, and what are you building?
We experienced an outage on Codex today. The issue is now resolved and Codex is back up. Sorry for the disruption, and thanks for your patience.
GPT-6 Astra helps @harvey turn stacks of documents into structured legal drafts, so lawyers can focus more on strategy.
Get lost in your side projects. One builder at our GPT-6 hackathons brought real star maps and Astra to help you find your way home.
See how surgeon @pridgenmd uses Codex to build his own tools and review scientific literature on PubMed:
Personal, work, side project account, other side project account. Build across all of them. Multi-account support is now available across most plugins. [Quoting @mxstbr]: Starting today, you can connect multiple accounts with most plugins in ChatGPT! 🎉 Bring…
You handle the reps. Codex handles the repo. Talk to the voice agent in Codex, powered by GPT-Live-1. [Quoting @cdngdev]: you can use codex voice from your phone now, connecting to your computer from anywhere!! @axbehr and i got to star in this new codex ad,…
You can just build (physical) things. [Quoting @natalieyeo]: "Hello World" from this cute physical Codex pet! To all the @OpenAIDevs Day 5 of building with Astra
GPT-6 Astra helps @cognition’s Devin back up “it works” with tests before the team ships.
GPT-5.5 will remain available via the OpenAI API Platform and in Codex sessions authenticated with an API key: [Quoting @ChatGPT]: On October 14, it's time to say farewell to GPT-5.5 in ChatGPT, ChatGPT Work, and Codex across all plans. If you use GPT-5.5 in…
GPT-6 Astra in Codex is helping test code end to end at @perplexity_ai. @randomjohnnyh uses it to build test harnesses and mock third-party API responses, so he can check how the pieces work together.
