There are roughly 100x more people who use code than who can write code.1 As code that “just works” becomes easier to generate, this group may be the biggest prize of all — if you can get the agentic interface right.

A key trend we have been tracking over at AINews is the absolute explosion in Codex usage this year, with MAU now up >10x from Jan 2026. Less than two weeks after their July 9th launch, OpenAI said ChatGPT Work and Codex had reached 10M million users combined (as we cover in the pod, Codex now powers ChatGPT Work, so all ChatGPT Work users are now users of the Codex harness, even if they aren’t traditional engineers) — showing the early innings of what happens when you graduate from coding agents to knowledge work agents:

We’ve been calling out how coding agents are “breaking containment” to do everything else this year to power every other part of knowledge work - and it started with the org chart, with a major reorg last month that amounted to two of Codex’s most prominent leaders, Greg and Tibo, taking responsibility over product and ChatGPT specifically, completing a “Superapp” consolidation cycle first discussed in March.

With these updates Codex is no longer just a coding tool. In June, OpenAI said knowledge workers already accounting for roughly 20% of Codex’s user base and growing more than 3x as quickly as developers. A product dedicated for knowledge workers was being pulled out of the Codex team.

However, knowledge work has a different set of problems and environments than coding. For decades, knowledge work has been scattered across different primitives like documents for writing, spreadsheets for analysis, slide decks for communication, and specialized applications for everything else. ChatGPT Work now enables users to work across every primitive with agents. Instead of opening an application and manually operating its features, the user can describe an outcome and collaborates with an agent that can assemble the tools, context, and artifact needed to reach it.

From building no-code products at Airtable to leading Productivity Engineering at OpenAI, Akshay Nathan has spent much of his career trying to make the power of software accessible to people who do not write code. In this episode, Akshay joins swyx and Vibhu to unpack the launch of ChatGPT Work, why Codex unexpectedly took off among non-developers inside OpenAI, and the company’s broader plan to bring useful agents from software engineers to knowledge workers and eventually everyone.

We go deep on the shared agent harness behind Codex and ChatGPT Work, why OpenAI brought the experiences together without making them identical, and how persistent computers, artifacts, Sites, plugins, memory, and sub-agents are changing what people can delegate to AI. Akshay explains why some teams are replacing decks and spreadsheets with interactive websites, how agents can gather context across code, Slack, documents, and local files, and what OpenAI learned from personal-agent products like OpenClaw.

Side note: also don’t miss Abhihek’s sandbox track keynote at AIE, which now powers a lot of the sandboxing for ChatGPT Work… and yes was also broken by an unreleased OpenAI model in the recent HuggingFace incident.

Akshay also reflects on how AI is transforming product development itself: why more people will become generalists with a specialty, why ideas and taste become the bottlenecks when almost anyone can build, why LLMs still struggle to generate genuinely grounded new ideas, and why teams must distinguish increased motion from actual progress.

We discuss:

Transcript

Introduction: Akshay Nathan, ChatGPT Work, and the No-Code Arc

Swyx [00:00:00]: We’re here in the studio with Akshay from OpenAI. Welcome.

Akshay Nathan [00:00:07]: Thank you.

Swyx [00:00:08]: And with our trusty co-host, Vibhu. So you recently launched ChatGPT Work. You lead Core Product Engineering. It’s been a long journey, into all this. I find it very interesting that you started with no code or low code, with Walrus and Airtable. And to some extent, ChatGPT Work is like the super app of super apps of, well, here is the ultimate no code. You just write a prompt.

Akshay Nathan [00:00:32]: Yeah. It’s funny how things come, full circle. I think for a long time in my career, I started my career working consumer fintech, but then after that, like, there’s this hypothesis that, the things that we were able to do with code, like, as engineers, like, if we could bring that to many more people in a more, accessible way, then that would be truly magical. We were working on a startup. It’s funny, like, before LLMs, before vision LLMs, on how to do automated testing with AI. It was just kinda jank, back then, but doing what we can, and then worked at Airtable for a while on the same thesis that, like, if we can bring a database or the primitives behind a database to people, that’d be really useful to them. But once LLMs came onto the scene, it became clear that, this was the missing piece, like, the missing technology required to, like, bring the magic of code to everyone without them having to know what’s going on underneath the hood. And so, like, I think this launch and a lot of the stuff that we’ve been up to is, like, the manifestation of that.

From Walrus and Airtable to OpenAI

Vibhu [00:01:33]: How was stuff when you joined? So you joined OpenAI 2023. Now we’ve got, so much more stuff, so ChatGPT, Codex app, ChatGPT Work. Have things changed?

Joining OpenAI and What Hasn’t Changed

Akshay Nathan [00:01:44]: I think the more interesting thing is how things haven’t changed. Like, one, I joined I remember when I joined, it was, like, five hundred people. One thing I was worried about was, like, I was looking for something, more early stage and, like, was it gonna feel startup enough? And I joined, and I was like, “This feels even more startup-y than I could ever imagine.” And, like, that really hasn’t changed even till now. I think the, like, level of, like, bottoms-up ambition and, like, the ability of anyone to, like, do anything or have an idea and ship it is really cool. But on the, like, mission side, I think what was really compelling to me is this mission of, bringing frontier intelligence to everyone. Like, building AGI and then bringing it to everyone. And, I think acknowledging back then that, like, that vision is gonna, not be a linear progression. Like, we’re probably gonna, like, try different products and have different things that succeed and don’t. But the vision has stayed the same, and the mission has stayed the same, and we’re starting to see the pieces, fall together, and that’s really cool.

Enterprise Lessons: No One-Size-Fits-All AI

Swyx [00:02:40]: You worked on Enterprise. What A lot of people never touch ChatGPT Enterprise. What is something that you learned from there that you’re bringing into your work now?

Akshay Nathan [00:02:52]: I think how there’s no one-size-fits-all solution in Enterprise. I remember in the early days of ChatGPT Enterprise, like, when we talked to customers and, like, everyone. That was, like, when I think it was a year after ChatGPT was released, and everyone was so excited to bring, AI into their enterprise. And, there were all these teams being stood up. It was, like, the AI deployment team with, like, these enormous budgets. And if you asked anyone, like, what were they excited about? Like, what were they excited about solving? Like, at first, you’d get, like, kinda like the baseline answers of, like, “Yeah, we have all this context and data and all this stuff.” But then if you ask them, like, “What was, like, a discrete use case that, like, they want AI to enable in their workplace?” You get such a different, like, variance, like, explosion of, different types of answers. And it’s interesting, like, you using, like, these models and these products, you have this box, and you can say anything to it, which is the magic. But it’on the flip side, it also means that, like, you don’t know what to do with it. And in Enterprise, I think a big part of that is, like, meeting the users where they are, like, what use case were they trying to solve, and then teaching them how they can use AI to, like, gain leverage there.

Swyx [00:03:56]: Do you meaningfully differentiate that from forward-deployed engineering?

Akshay Nathan [00:04:01]: I think there is the go-to-market side of it and then there is the product side of it. I think you need someone on the product side. And I think, like, however good we get at FDE motion, like, I think at the end of the day, if we have a user who’s, like, looking at their computer or looking at their phone, like, it’s our job in the product to, like, be enabling them and showing them where to go. So we’re really excited about that.

Vibhu [00:04:24]: Do you think there’s been changes, over the past three years of adoption? So there have been, step function changes. You have reasoning models and whatnot. Is there still the same problems of Enterprise has black box, don’t know what to do with it, or have things changed?

Adoption, Agents, and the Next 10x Market

Akshay Nathan [00:04:39]: We’re seeing now that, like, there’s this huge uptake, right? Everyone is extremely excited about it. It feels like, many people are, millions, hundreds of millions of people are using ChatGPT. They understand, like, how generally to work with AI. But then, like, every time, like, a new capability gets unlocked, so now, like, we’re seeing with agents, like, there is probably a contingent of, like, early adopters still who, truly get it, who are like, “ we you can do anything. You just have to make sure the right context is there, it’s connected to the right tools, and that you are supervising it, but, like, anything is possible.” But then there’s, like, this, like, 10x or 100x bigger market where, like, they don’t yet get that, or they don’t yet see that. And so I think that’s the next stage here. So to answer your question, like, I think the adoption is there and growing fast, but I think the opportunity is, like, far bigger than that. That’s where we wanna play, especially with ChatGPT Work.

ChatGPT Work, Codex, and the Super App Merge

Swyx [00:05:27]: Yeah. well, let’s, let’s skip ahead to ChatGPT Work. only, like, a month ago or so, announced. what was the decision process that led into it? there was this, overall merging of the super app. Is that what we’re officially calling it? you deprecated the browser as well. Just, summarize your last, like, couple months of working on this thing.

Akshay Nathan [00:05:50]: Yeah. It feels like forever now, but it’s only been a few months. I think maybe the one, impetus that, like- Is most salient is when we release Codex, or even internally had Codex, like, it was really surprising to us, I think we recently put out some stats on this, that there was this, like, real inflection of, like, adoption among non-developers at OpenAI. And, I, through this product development process, like, would go to, like, these UXR sessions to talk to people internally. And the thing that stuck out to me is, like, one, like, you go talk to, like, strategic finance or marketing or whatever, and they’re all using Codex for, their use cases. That part’s cool, but the thing that really stuck out to me is how proud people were that they were using Codex. Like, how, like

Swyx [00:06:34]: It’s like, “I’m not supposed to be using it, but I am.”

Akshay Nathan [00:06:36]: It was that. It was, like, that they were, early to this, like, new thing, but it was also this thing of, like, they felt like they had a superpower, right? And, what we recognized then is that, like, the power of Codex, the power of agents, like, we already had this massive distribution base of people who have, come to know and love ChatGPT. Like, how do we show that to them? Like, how do we bring it to them? Which is, like, a hard product problem, and it’s, like, a tricky thing, right? There’s many ways you can go about it. And so that’s what we called the Merge and the Super App over time, and ultimately launched it in ChatGPT Work, is how do we do that? But it came from that initial realization that, like, the power was not only for developers, like, much earlier than probably even we thought. Like, it could be extended to everyone.

Swyx [00:07:17]: How do you see the products differently? So, like, who is it for, right? So Codex started out even CLI, then app. Now there’s a merge of ChatGPT Codex and ChatGPT Work, so is it the opening for the average user, for enterprise, for work? How do you position it?

Akshay Nathan [00:07:36]: I think we want to get it to position it for if you’re doing work-related things, for lack of a better word, right?

Who ChatGPT Work Is For

Akshay Nathan [00:07:42]: I think productivity is what, like, the pillar that I support. Like, that’s the name of the team. And the reason for that, the reason we call it productivity and not, like, enterprise or, like, work or something like that, is because there’s also personal productivity, right? And, like, I think ChatGPT Work is I’ve seen people do things in their personal lives that you wouldn’t classify as, like, work technically, but, like, these agents are, super capable for. Like, one recent example that someone posted about, on our Slack is, like, someone had, like, a missed package, like they didn’t receive it, and then they got, like, the picture of it, from Amazon or whoever the courier was, and they, like, asked ChatGPT Work to, like, find out where that package is. And, like, the agent, is extremely tenacious and, like, took the image and, like, looked at a bunch of, like, listings around their neighborhood and figured out exactly the apartment complex in which the package was, like, gave them some information. And so, like, I think there’s all these things that, like, you, work-related or productivity-related things, I think that’s what we want the product to be. You asked about Codex. I think we think Codex is, a durable brand, but we have a principle that, like, the user we don’t want a user to get stuck in a tab or an experience where they don’t get the power of the product. And so, like, everything that you can do, in the Codex portion of the product on desktop, you can do in ChatGPT Work and vice versa. But we made some opinionated product decisions on, like, how much of the Git state, if you’re in a Git repo, do we wanna expose to the end user? Or how much do we wanna make the experience of seeing the agents thinking, like, diff forward so that you get exposed to the diffs out of the box. And then, like, on the safety side, like, how do we wanna think about, like, sandboxing and making sure that we have the right defaults in one state versus the other? So, there’s, like, some opinions that go behind that, but we do want We don’t want the user to need to choose which experience they’re in.

Swyx [00:09:26]: That is a good goal for AGI, right? Like, people don’t want, like, to hide to choose what version of AGI they want. They just want the AGI to decide for them. can I get an answer or, like It’s not super clear to me. Is the Codex harness and the ChatGPT Work harness the same? Is it just UI affordances, or are there prompt level or even deeper differences?

Shared Harness, Different UX: Codex vs. Work

Akshay Nathan [00:09:49]: So the harness is the same. The harness is shared. on In both of the products, we made improvements to the harness to make it good for knowledge work, especially as it relates to plug-ins or computer use or artifacts. You get that power regardless of which experience you’re in. On the UX side, there’s opinionated takes that we have when you’re in Codex mode, what the UX should be how the UX should behave, and some stuff around the sandbox like I mentioned, but the underlying harness and capabilities should be the same.

Swyx [00:10:16]: I’m just kinda curious. Maybe we can, – Is there a query that we can run that would look different in the two modes?

Akshay Nathan [00:10:23]: Yeah. I tried to create, like ask it to create, like, a retirement calculator spreadsheet or something, in both modes. And then in Codex mode, you might have to be in a repo for this, but you’ll see, like, the diffs of, like, the sheet that it’s creating and stuff like that, and the file edits. But in Work you won’t be able to see that.

Swyx [00:10:42]: I think that’s, that’s super clear. And then also the other thing I wanted to dive into was your, the productivity team. what else is there? first of all, what are the top-level teams other than productivity? Isn’t productivity everything?

Productivity Teams and Core Chat

Akshay Nathan [00:10:55]: So

Swyx [00:10:55]: Science?

Akshay Nathan [00:10:55]: We have a team focused on ChatGPT. Like, the core chat experience, for consumer, which is like, not, I think all productivity. Like, there’People are using ChatGPT every day for search to, figure out how to write messages to loved ones, to think about, how to, like, learn a new topic, et cetera. And so there’s so much more inside to create images. And there’s so much more in chat that, the hundreds of millions of users are using that warrants, like, a very dedicated effort. And there’s teams focused on enterprise and infrastructure and API and stuff like that, so.

Swyx [00:11:33]: I will bring it up.

Retirement Calculator Demo and Git-First UX

Swyx [00:11:34]: Yeah. So I have them both running. This is ChatGPT Work. There’s a Codex version here. I picked “Five Little Ducks” song, so this will take a while.

Akshay Nathan [00:11:43]: Huh.

Swyx [00:11:43]: I think we’ll just keep it in the background and, as they finish, we’ll look into some of the differences.

Akshay Nathan [00:11:48]: Yeah. But immediately, I think if you flip back to the Codex version you’ll see that,

Swyx [00:11:53]: That it assumes

Akshay Nathan [00:11:54]: Like the

Swyx [00:11:54]: It assumes Git. Yeah. Yeah.

Akshay Nathan [00:11:56]: The, like, dynamic island assumes that you’re in a Git repo. And you might miss some stuff because some of it is, like, in the actual chain of thought with those changes and how we display that, but yeah.

Swyx [00:12:07]: Is there an unintuitive like, is there a thing that you wanted to ship and then you got feedback, and you were like, “No, let’s not do it?” Like, what’s the thinking behind that?

Why Merge the Experiences

Akshay Nathan [00:12:14]: In, ChatGPT Work?

Akshay Nathan [00:12:17]: I think one direction we could have gone with this is, like, keeping the experiences, like, completely separate. So it’s like, why

Swyx [00:12:22]: Different apps.

Akshay Nathan [00:12:23]: Exactly, like different apps or even in the same app, like different, completely different experiences. Like, why merge it all? Like, what is. Codex, people love. Like, why bring these products together? And I think the intuition here is that, like, all of our jobs are, like, changing dramatically with AI. Like, for, like, every few months, like, I feel like I wake up, and I’m, like, doing a completely different thing than I was doing a few months ago. And my hypothesis here is that, or I should say our hypothesis is that, like, part of what we’re, we’re building, this technology is giving people leverage. Like, the things, maybe it’s the more mundane parts of your job or parts that, like, if you were able to automate, you’d be able to share more ideas faster or whatever, like, you’re able to do now. And because of that, like, that might blur the lines between someone who’s, like, only writing code or creating strategy docs or, planning events or, helping with marketing or doing podcasts or whatever, right? And so, like, these things are gonna get blurred over time. And so, like, trying to draw a hard boundary based on, like, the who you are is gonna be, is gonna be tough. And, like, we should enable users to choose, but we shouldn’t box them in. And so a lot of the work that went in here, like, keeping the primitives the same, like for example, plugins are, like, unified across, this product and ChatGPT and the cloud, was because of that. It’s this thesis that, like, eventually things are gonna come together and we don’t wanna be Like, we wanna be prescriptive about when to be in either experience, but we don’t want to box anyone in.

Swyx [00:13:45]: I wonder if there’s users who are very tuned to the old ChatGPT harness that is effectively now replaced by the Codex harness. I can’t imagine what that was, but maybe they’re more the more conversational side. Can you compare and contrast the two harnesses? ‘Cause only you’ve seen it.

Akshay Nathan [00:14:02]: Yeah. I think ChatGPT, the existing harness, like, still exists today. Like, it exists in this app,

Harness Engineering: ChatGPT vs. Codex

Swyx [00:14:08]: The classic, right?

Akshay Nathan [00:14:09]: The

Vibhu [00:14:09]: You just start a new chat, and you don’t go under Work, right?

Akshay Nathan [00:14:13]: Yeah. If you start

Vibhu [00:14:13]: So
