The coolest thing about Space Slides in ChatGPT is that it raises the ceiling on slide quality. With imagegen, I can make things I was never able to make before.
ChatGPT Slides has new ways to get your deck ready—and get everyone on the same page. • Work together in real time in ChatGPT: Share decks, edit together, and leave comments. Ask ChatGPT or your dot to turn feedback into updates. • Edit right on the slide: Click to change text, update charts, and move or resize images and shapes. To get started, ask ChatGPT to "create ChatGPT slides" from a conversation or a file you've shared. Present in ChatGPT, or export to PowerPoint or Google Slides. Available on Pro, Business, and Enterprise plans. chatgpt.com/features/slides/

Super proud of this launch! We skipped single player editor and went straight to multiplayer collab where agents and teams can all work in the same slide deck. This is just the start, roadmap is insane! Drop any feedback below 👇

@tarstarr @neelajj @schwa23 he just… tweeted it out
What is ChatGPT Space, that is the question. Endearingly awkward at times because it's the actual team working on it. What would you like to see next?

Spaces is the most underrated recent ship from y'all by far. Needs some refinement but honestly feels like you're working towards something magical @davis7 showed me some demos that blew me away

Insane how Computer Use has dropped the cost of switching software to zero. Codex mirrors my Apple & Google Maps lists so I can just... use whichever one is best without losing my places

Codex is one of the most important untold stories in the history of technology. A year ago, it was a scrappy effort in a quiet corner of @OpenAI. Its cloud product hadn’t found PMF, and the team was starting over from scratch. Less than 12 months later: - Codex swallowed the flagship ChatGPT desktop app from the inside (it literally runs as com.openai.codex on your Mac) - Codex and ChatGPT for Work hit 40M+ weekly users across engineering and knowledge work - Its leader @thsottiaux was elevated to run all of OpenAI’s core products, including ChatGPT, Codex, and the API How did they pull it off? They trained their own dedicated model line, separate from ChatGPT, with researchers and product builders sitting on the same team They built four different products in a single year (cloud → terminal → IDE sidebar → a desktop app with no code editor at all) as every model leap made a new form factor possible They used Codex to build Codex—so a handful of people could prove a new product in weeks instead of arguing for it in meetings I had a front-row seat to the whole arc—from their failed Cloud launch, to OpenAI’s offices the night before GPT-5 dropped, to the day Codex took over ChatGPT. And I spent months interviewing @gdb, @thsottiaux, @embirico, @mia_glaese, @aambrosino, and @edbayes to get inside how it all went down. Here is the full, behind-closed-doors story of the team that remade OpenAI: every.to/p/how-codex-happene… We’re pushing the boundaries of how stories like this are told. This piece is completely agent-native—designed to be read alongside your agent inside ChatGPT’s in-app browser: - Every interview transcript is included in full: Click any quote and you (or your agent) can see the exact conversation it came from. - Built for your agent to explore: Ask your agent to pull out product lessons for your team, cross-examine the transcripts, or find insights I missed when writing the piece. It’s a story about the future of software—built to be read with an agent: every.to/p/how-codex-happene…

As much as I've been crashing out about ChatGPT today, there's still a ton of good stuff they've added "Spaces" was one of the dev day announcements that I've seen basically no one cover which sucks. It's an awesome new feature, if I had to rank the dev day announcements: 1) GPT-6.1 Sol 2) Spaces 3) Ultrafast 4) plugins/mcp stuff 5) "sign in with chatgpt" Sadly dots and cloud were both a mess, but that's a topic for another time. Spaces is effectively notion inside of chatgpt. I've set up a space for my YT channel which is now the pipeline for making videos. It's got: - the steps/checklist for each part of the vid (planning, recording, editing, packaging) - examples - premade prompts for repetitive pieces I've got prompts for ideating a video and creating the associated notion DB entry in the right format, getting the video ready for editing in final cut with computer use, getting the thumbnail face(s) out of the footage and ready for making the thumb Having this kind of "artifact" system be built in and naturally flow back and forth with normal codex prompts is very useful. It has issues, mostly around UX stuff. The "tabs" are weird and the embedded thread for each "page" is strange to use. It's a normal codex thread but also not, when u click on it it sometimes opens full screen sometimes in the bottom right. You can't have two subpages next to eachother, just the main page and then a chat next to it + subpages in the same "pane" It's pretty well integrated into the full system, you can tag spaces from any thread and again the threads u start in the chat inside of them are real codex runs so the computer use stuff I want to use does work quite well. This is what I was really talking about when I said there are a ton of products fighting inside of one app. This is one of many things rolled up in codex that most people don't know about which kinda sucks because it's great. Another great example of this was the in thread visualizations. Everyone thought it was novel and cool when we put it in T3 code, but it's been in codex for months (I stole it from there)

See you in Space!
At DevDay, we introduced ChatGPT Space: a new home for your team to collaborate with AI to get work done. In Space, you can create living documents with ChatGPT and the people you work with. Turn a messy conversation into an organized plan, and invite a teammate to edit together or leave feedback in comments. Tag ChatGPT or your dot to make changes or help with next steps. You can also ask ChatGPT to keep the page updated from your connected tools, so you can focus on the work—not updating the doc. See how it works below and go to chatgpt.com/space to get started. Available on Pro, Business, and Enterprise plans on web and desktop.
