ChatGPT Work: Your New Partner for Ambitious Tasks and Complex Projects
I am introducing ChatGPT Work, a new agent powered by GPT-5.6 that transforms how we tackle ambitious projects. It connects to your apps like Slack and Microsoft Teams to gather information, create finished materials, and execute complex workflows independently. Whether automating month-end finance closes or turning discovery calls into tailored proofs of concept, this tool handles repetitive tasks so you can focus on high-value strategy and customer relationships.
In sales, ChatGPT Work turned a discovery conversation into a tailored proof of concept for a mission-critical problem within 24 hours—a process that normally takes weeks.

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/ only contains the new ChatGPT.

This unification is garbage. Chats that are about topics other than programming projects are relegated to a tiny, unsearchable popup window. Renaming the old app "ChatGPT Classic" implies that it will be discontinued at some point. This is a serious regression. What existed before worked fine.
I would expect the mode switcher to include a Chat mode, which would recreate the old, chat-focused UI, for asking about random topics. So, that's basically gone now. Technically, it's hidden and severely castrated.
I hope someone from OpenAI reads this. You guys have made a serious design mistake. I suspect you'll be getting a lot of support requests along the lines of "Where did all my chats go?"

Anthropic just changed their web interface yesterday to have Chat versus Cowork as well, and every time I look at it, I'm so confused. I'm still so unclear when I'm supposed to use one or the other or the other.
Now the 'ChatGPT desktop app' (the Codex app, renamed) also has the split between work and code, and as far as I can tell, all it does is change which plugins are loaded by default to include Office ones when you put it in work mode. Perhaps it also changes the system prompt slightly?

This thread is so spot on but I can also imagine the product development internally is moving so fast that they're trying to reconcile everything and can't. And this is the huge mistake so many companies make. Leave what's working alone. Build new adjacent things. It's clear they want to make money and work or code is the focus of enterprise. But never rename something Classic...so bad.

I have a longer version of this, but in summary
So my understanding of the differences between chat, code and co-work; but may well be wrong!
Chat is the human, talking directly to the LLM - old school. Very basic can create docs etc - but saves in a temp folder. No real access to your local PC.
Cowork / work - Human talking to an agent, which can then use tools to do work. Also runs in a container, allowing it access to your drives/computer.
Claude Code / Codex - No longer in a container, full access to the computer, depending on what permissions you give. No longer locked in a container. + The agent is more focused on coding than cowork / work.

So, Claude Cowork for OpenAI? Feels overdue!
I've loved using Cowork recently for sourcing decisions. Things where seemingly everyone's out of stock or questionably reputable, just let Cowork spin for 20 minutes, find the best new and best used options that meet your requirements, probably also suggesting a different item that does the job and is available for cheap. I've done it enough that I'm starting to loathe clicking through these sites myself.

I had switched from Claude Cowork to OAI Codex a month ago. This seems like a rebranding and app merging to make it more obvious. And switching between the newly named "ChatGPT Work" vs "ChatGPT Code" mostly just seems to increase the verbosity of technical outputs, while using the same harness underneath.
I switched because Cowork felt like a bunch of features thrown in by engineers without thought to the UX. Codex solved a lot of those issues for me
- remote control from mobile has native approval dialogs, and you can start new threads from mobile
- you can remote control from another laptop
- computer use doesn't hijack my computer from me because it uses a11y trees instead of screenshots
- it was super unclear which skills were accessible to which surface (claude chat, cowork in app, code in app, code in cli).
- codex chooses the right browser profile and gets stuck less often than cowork + claude-in-chrome. I know there are 3P skills to use playwright or the chrome CDP, but I've found the native browser use most productive even if slower.
A few people here are missing the old ChatGPT app, but I found myself increasingly using Codex for casual chats too, and never using ChatGPT. You never know when the conversation might evolve to requiring tools in Codex, so no real downside to it. Yes, separation of work and personal accounts, or connecting multiple google accounts, is still unsolved on both Codex and Cowork AFAICT.
For a bit, I got FOMO because of Fable, but now it l […]

I think these kind of semi-coding agents--but hosted--are the future for enterprises. Claude Tag, Claude Cowork, now Work by OAI.
Agents-on-your-machine clearly have their place, but for many workflows this is too unruly. Hence, the "long-running agent running on shared infra" pattern.
I think this is where the ball is headed. I'm building towards an open source version of this[0]. Still just working on the core, but hopefully soon self-hosted versions can be built on top.
