Quick answer: On September 29, 2026, OpenAI turned ChatGPT into a shared workspace at its DevDay event. You get an AI agent that keeps working after you close the app (a “Dot”), documents you build WITH it (“Pages”), a shared room your team works in (“Space”), and a way for it to show up right inside Slack or Microsoft Teams. Your job is still yours. What changes is what your next hire should already know how to use.
September 29, 2026. That’s DevDay, OpenAI’s yearly “here’s what we built” event, and this year it was ChatGPT stopping being a chat box and starting to look like an actual office.
I’ve been saying this for a year. AI stops being a toy the moment it stops living in one tab. That’s exactly what happened this week.
OpenAI is building a workspace, not just a chatbot
Every other update on this list is a piece of one decision. OpenAI stopped building a smarter answer box and started building a place where work actually happens.
The Decoder’s Matthias Bastian put it exactly right: this version of ChatGPT looks less like a chatbot and more like an operating system.
A chatbot is something you visit once and close. A workspace is something your team lives in all day. The business that trains its people to work inside it gets a head start. The business that keeps treating it like a search bar falls behind.
ChatGPT Space could change the way we all organize work
Space is the new shared room. Your team, ChatGPT, and its agents all work against the same project at the same time instead of everybody pasting into their own separate chat and losing the thread.
Picture your onboarding doc. Right now it probably lives in three places: a Google Doc, a Slack thread where someone asked a question about it, and whatever’s actually in your head. Space is built to be the one place. Your team builds pages, works through tasks, and keeps the context together instead of scattered across five tools.
Decrypt confirms Space rolled out on desktop and web for Pro, Business, and Enterprise plans. Plus subscribers don’t get it.
ChatGPT Pages: think Google Docs inside of ChatGPT
Pages are new documents built for you and AI to work on together. Inside one, you write, it researches, it builds you a chart, and you’re both looking at the same page instead of you copying its answer into a Word doc afterward.
Collaborative Slides are coming in the next few weeks on the same plans as Space, according to The Decoder’s DevDay writeup. Multiple people editing the same deck, agents included, then exporting to PowerPoint or Google Slides without losing your formatting.
If you’ve ever built a proposal by pasting ChatGPT’s answer into a Canva template one paragraph at a time, this is OpenAI admitting that workflow was always dumb.
Dots, Slack, and Microsoft Teams: your team can loop it in without leaving the room
OpenAI’s real headline feature this year is “Dots.” A Dot is a persistent agent. You give it a job, it keeps working after you close the window, it runs on its own cloud computer, and it can connect to more than 4,000 applications while it learns your preferences.
That last part is the piece most small business owners will actually feel first. Your team doesn’t have to open a separate app anymore. Someone types “@ChatGPT” in a Slack channel or a Teams thread, and it can turn that conversation into a project brief, or look at a bug report and draft a fix for review. Teammates can do this without their own individual ChatGPT license, on Business and Enterprise plans.
A first Dot comes included at no extra charge on Pro and Business Premium.
Meetings are moving directly into the AI workflow
OpenAI didn’t announce a meeting feature at this event. Nobody stood on stage and unveiled a transcription tool. This is my own read, and I want to be straight with you about that before you go looking for a button that doesn’t exist yet.
Look at the pattern forming. Dots keep working on a task after everyone leaves the room. Space keeps your team’s whole project in one shared place instead of scattered notes from a call. Line those two up and the meeting itself starts mattering less than what happens the second it ends.
You know the meeting where three people agree to something and nobody follows up on it? The tools to close that gap are getting built around meetings even without a “record my meeting” button yet. Whether your team actually uses them is still on you.
Plugins are becoming more important than people realize
TechCrunch reported OpenAI is expanding ChatGPT’s plugins with app-like interfaces, dedicated sidebar homes, interactive panels, file viewers, and automations built on the MCP Events standard. Developers can now build tools that live inside the conversation itself, and OpenAI named Canva, Figma, and Adobe as early examples.
Pay attention to this one even if you’ve never touched a plugin in your life. ChatGPT will soon recommend these tools mid-conversation. That’s a new shelf, and somebody’s product is going to sit on it. Right now most small business owners have no idea that shelf exists.
GPT-6.1 Sol: a bigger shift than the name lets on
OpenAI shipped a new model, GPT-6.1 Sol, about a week after GPT-6 Sol. TheNextWeb quotes OpenAI’s own line on it: “near-Astra intelligence for a fifth of the price.” Translation… you get most of the power of their top model, Astra, at a fraction of the cost. It’s already live for Plus, Pro, Business, Enterprise, and Edu users inside ChatGPT Work and Codex.
The bigger story sits right next to it. OpenAI cancelled the planned GPT-6.1 Astra model. Al Jazeera reports that Saachi Jain, OpenAI’s head of safety systems, said the model failed internal tests for staying inside the scope it was given and communicating honestly about what it had actually done. A company willing to pull the plug on a model that failed its own safety bar is a company worth watching. Remember that the next time someone tells you AI companies don’t care about getting it right.
The $500-a-month ChatGPT plan (and what it actually buys)
OpenAI launched Pro 500, a new $500-a-month tier with the highest usage limits ChatGPT sells, a Dot included, and access to “Astra Ultrafast.” Engadget reports Ultrafast pushes Codex output up to 300 tokens a second, up to eight times faster than standard.
You don’t need this. I want to say that plainly because a headline like “$500 a month” is built to make you feel behind. This tier is built for teams running heavy coding work around the clock, not a solo service business owner answering client emails. The $200 Pro plan came back too, with a smaller allowance than before… Engadget reports Codex usage on that tier dropped from 20x what Plus gets down to 10x. For almost everyone reading this, Plus is still the plan that makes sense.
Codex shows us what asynchronous AI looks like
The Decoder reports Codex now works on your own computer, from your phone, or in the cloud from any device. You hand it a coding job and it keeps going without your laptop open.
You may never touch Codex yourself. Watch what it’s teaching us about how AI is supposed to work now, because it’s the same shape as the Dot: you hand it a job, you walk away, and it’s done when you come back. Ask that question about every AI tool you bring into your business from here forward. Can this one work while you’re not looking at it?
See What ChatGPT Says About Your Business
Right now, someone in your city is asking ChatGPT who’s the best at what you do. I’ll go ask that exact question myself… and hand you back the real answer, word for word, with live screenshots. Not a guess. Not a summary. The actual sentence AI is already saying about you, or about someone else instead of you. Before your next customer reads it first. Custom to your business. Free.
What you actually do with all of this on a Monday morning
You don’t need Space, a Dot, and Pages all running by Friday. You need one thing. Pick whichever piece above made you say “oh, we do that badly.” Maybe it’s the meeting nobody follows up on. Maybe it’s the proposal you still build by hand. Open ChatGPT this week and ask it to help you fix that one thing first.
Nobody is behind on this. It’s never going to be this dumb again, so play with it now while the stakes are low. If you want a second set of eyes on where your own business actually stands with AI right now, that’s exactly what my free AI visibility check is for.
FAQ: OpenAI’s September 2026 update, plain English
What is a “Dot” in ChatGPT?
A Dot is a persistent AI agent. You give it an ongoing job, it keeps working after you close the chat, and it reports back inside ChatGPT, Slack, or Microsoft Teams. A first Dot is included free on Pro and Business Premium plans.
Do I need the $500-a-month ChatGPT plan?
Almost certainly not. Pro 500 is built for teams running constant, heavy coding work through Codex. A solo service business owner or small team is well served by the Plus plan, the same plan I walk through in how to train ChatGPT to recommend your business.
What happened to GPT-6.1 Astra?
OpenAI cancelled it. The company’s head of safety systems said it failed internal tests for staying within scope and communicating honestly about what it had done, so it never shipped. GPT-6.1 Sol, a different and cheaper model, launched instead.
What’s the difference between ChatGPT Space and ChatGPT Pages?
Space is the shared room your whole team and its agents work inside. Pages are the actual documents you build together inside that room, the way a Google Doc sits inside a shared Drive folder.
Should my business start using plugins?
Worth watching. ChatGPT will soon recommend plugins mid-conversation, which means a new discovery channel is opening for tools built on top of it. Skip building one. Know it’s coming.
Always keep jumping.
