I just installed this. I am very confused. I no longer have a Codex app on my computer. ChatGPT is now Codex. But what happened to ChatGPT? Where am I supposed to casually chat? Also, when you toggle btween ChatGPT Work and ChatGPT Codex, nothing changes. This is super confusing. Can someone from the OpenAI team clarify the difference btwn the modes? Does chatgpt work have more business-y related plugins turned on by default? Edit: So it seems like the only place you can actually chat with chatgpt is in an awkward homeless nested window. idk. The chatgpt interface wasn't great (desperately needed artifacts), but I still used it a lot. I can't see this change going well with a lot of the casual users. Edit2: In their awkward homeless nested chat mode, you cannot even edit past messages. this is a mess, why was the team so zealous to pull the switch on unification in this state? guessing there was internal pressure to juice codex's growth but, based on what im seeing, they did it by torching chatgpt? Edit 3: Ok so it seems like ChatGPT is still around, but renamed to "ChatGPT Classic". Seems like it wont be long for this world because there's no place to download ChatGPT Classic should you choose to uninstall it. The dmg at https://chatgpt.com/download/ https://chatgpt.com/download/ only contains the new ChatGPT.

The only difference I can see is that the controls for local/remote, branch, and worktrees disappear, and instead it shows office suite plugins. I would presume it affects the system prompt in the background? Very confusing. But I do find it potentially interesting to treat general office work no differently from coding, which is something I had already been using Codex for in many ways before today

It’s all ChatGPT under the hood. Even though it says Work or Codex or whatever you can just ask it whatever you want, and it will work.

  > Even though it says Work or Codex or whatever you can just ask it whatever you want, and it will work. No it's not. Codex creates a new folder in `~/Documents` in iCloud drive/OneDrive for every single thread you make. Furthermore, these threads are also polluted with your global AGENTS.md file, as well as all other developer_instructions that are injected by the harness. I want my chat isolated from work contexts.
  - DANmode 2mo ago
    So, ChatGPT.com? What functionality are you seeking from a native app “for chatting”?
afruitpie 2mo ago
Sad, I liked that ChatGPT had a native app on macOS. I don’t understand why OpenAI and Anthropic have to rely on vending universal apps when their whole MO is code being dirt cheap.
- postalcoder 2mo ago
  Same. I don't see why they thought this was a good move.
  - mysterydip 2mo ago
    maybe they asked chatgpt about it :)

      You’re absolutely right and your solution is actually a better implementation.

        Haha. I love the Claude speak.
    - jostylr 2mo ago
      I asked ChatGPT about this change and my version, with knowledge of how it and I work together, certainly prefers the old one.

  AppKit and SwiftUI and WinUI are all meh for rendering lots of text. Chromium is quite good at it. Plus they have lots of embedded web content these days and managing webviews is a relative pain vs it all being one webview
  - stogot 2mo ago
    Why is a browser tool better at rendering text than native?

  Seems the old ChatGPT is still on computer but renamed ChatGPT Classic (no longer downloadable), so clearly being deprecated. But just don't understand how the whole CHATGPT Chat History Chat feature is essentially gone other than seeing at the past 3 or 4 in a tiny popup window. Glad everyone is as confused as I am, so hopefully an announcement from ChatGPT clarifying all this.

I think the idea is that there should be no difference between 'casual chat' and 'serious chat'. why not chat in codex

  Does codex not have a pre prompt about being a coding agent like claude code does?
  - dominotw 2mo ago
    I think coding models and harness are good/better at general questions and simple problems. something about coding being general format to think.

The old ChatGPT is now ChatGPT Classic. Codex is now ChatGPT. There is a funny interaction in the Microsoft store, where ChatGPT turns into Codex when you click on it: https://f003.backblazeb2.com/file/sharexxx/ShareX/2026/07/ApplicationFrameHost_URZLuh4R9oCp8umH1i.gif https://f003.backblazeb2.com/file/sharexxx/ShareX/2026/07/Ap... (Also GG @ MSFT for opening a nag about Windows Hello twice while I wanted to stop the recording.)

I have updated Codex and it's now ChatGPT. And the chat in Codex is badly broken and doesn't support the one feature I use in almost every chat. Good job.
- naiv 2mo ago
  which feature?
  - egorfine 2mo ago
    Temporary chats.
    - steve1977 2mo ago
      Well, at least for me, they are not broken. They are gone.
- john_strinlai 2mo ago
  >And the chat in Codex is badly broken and doesn't support the one feature I use in almost every chat. what is badly broken about it, and what feature does it not support? im a pretty casual user, so i guess i havent noticed this bad breakage.
  - egorfine 2mo ago
    Everything. The current implementation is unusable. If you see differently then probably you are looking at Codex chats, not chats.
    - john_strinlai 2mo ago
      whether i use the new "chat" button that just appeared after the update, or use the familiar chat underneath the "projects" heading, everything appears to be working just fine. (i am using "ChatGPT Work" not "ChatGPT Codex") is there a 3rd chats somewhere that i am missing?
bathory 2mo ago
On Windows, ChatGPT is now known as ChatGPT Classic, and Codex is now known as ChatGPT (Beta).
- partiallypro 2mo ago
  I see they are fully embracing the Microsoft model, soon we'll have ChatGPT Classic, ChatGPT (Beta), and ChatGPT (New)
cush 2mo ago
I just downloaded the new dmg and it's the old chatGPT. Maybe they are listening?
steve1977 2mo ago
It really is a mess. An hour or so ago, the download for macOS was called ChatGPT.dmg. However the app in there was still called Codex. But it installed ChatGPT. But it seems to be fixed now. Also, subtitling Work with "For getting work done" and Codex with "For developers" is a bit aggressive towards developers ;)

>Also, when you toggle btween ChatGPT Work and ChatGPT Codex, nothing changes. This is super confusing. This is the weirdest thing. It's completely unclear even if I was using the app for "work" rather than "coding" why I wouldn't just use the "Codex" option. Why even bother toggling? Can Codex actually not do any of the things in "Work"?

fragmede 2mo ago
Lol what a shit show. It was fine the way it was. Why'd you break it, OpenAI? What product manager talked you into thinking this was a good idea? Don't they have access to ChatGPT to talk them out of it? Of course, I'm a random on the Internet who doesn't get it, but what a dumb move. ASI can't come fast enough.
- nozzlegear 2mo ago
  > ASI can't come fast enough. ASI is a myth used by these companies to justify their pursuit of regulatory capture.
z2 2mo ago
So will the new ChatGPT (Codex) refuse to respond at all after the 5-hour quota or weekly quota is used up? It always felt that 5.5 on the website was a lot more generous than the Codex version. And at least the website/old app could downgrade you to a lower model if you used up that quota.
danorama 2mo ago
So let me get this straight: 1) If you have the Codex desktop app installed, and you update from within the app, it replaces itself with the new chat-demoted-to-an-overlay app called "ChatGPT" and renames your existing ChatGPT app to "ChatGPT Classic." 2) If you get the new ChatGPT app and replace your current app with it, you don't get a "Classic" app and there's no way to download it. 3) They really named an app "Classic." Naming your app Classic is putting a bright red sign on it that says "this app will be abandoned soon." They might as well have called it "ChatGPT Sunset." If this is all true, that is certainly...one way to do product management.

  Chat is there... it's just can't be in a full-screen anymore.
  - gitgud 2mo ago
    Not allowing full screen is the most insane thing for a “chat app ported from the web”… the browser probably has a better experience now…
    - 8n4vidtmkvmk 2mo ago
      Always was better IMO. I just pinned the browser app as a desktop app and have been using it that way for many months. Works great.
    - Razengan 2mo ago
      The best way to access ChatGPT "chat" was always on ChatGPT.com via a web browser, not even the iOS app seems to have all the little things you can do on the web version. The Mac desktop ChatGPT app had weird issues like not being able to see the model being used by a chat inside a project etc. I just ended up installing ChatGPT Atlas and using that as an AI-only browser for all LLMs including Claude and Grok lol

    You can detach a specific chat window and make it any size you want.

I feel like the web is under attack. They want chatgpt in desktop app so they can start moving people away from chatgpt via web. Web being suspectible to automation is driving everything into locked down apps. The very toxic reddit.com a prime example of this -- forbidding mobile web access behind a timed wall.
- lobsterthief 2mo ago
  Yes, the side effect has been me using Reddit via Incognito, which means I don’t see it every time I open iOS Chrome, and also I’m not signed in, so after 14 years I’ve basically stopped using it. I guess with their IPO “the line must go up”. Very stupid, dark pattern.
