Codex

“OpenAI's most expensive model. It's on par with Fable in terms of pricing, but if you have a codec subscription, very subsidized, and not only that, it's also very efficient, meaning it doesn't take as many steps to complete a task.”

“Well, certainly there's been like ramp data, but around Codex starting to close the gap again with Claude Code.”

“Codex has been my CMO for the last like two months. Basically running our ads and giving me advice on AEO and SEO and what have you. And I find it much more preferable to talking to a real human consultant, which I've also done. And it's roughly the same resul…”

“Codex is like a hundred people making that thing better”

“I mean, if I bundle all of the cloud, cursor, codecs, it is one of the fastest growing parts and definitely faster growing than the UI of Glean, which is still by a large margin, a very high daily engagement driver.”

“Phone harness connects an agent like Codex or Cloud Code to a real iPhone or Android. Super cool, right? For iPhone, it uses Mac iPhone mirroring, and for Android, it uses ADB, so you don't have to, like, jailbreak it”

“In work mode, that's where under the covers, this is codex. We've removed some of like the coding UI, like you don't, you're not going to see a work tree pop up all of a sudden in, in work mode, but it is the same power to get things done”

“And actually with the Codex app the team who initially got it up and running and we're working on it we're super, again, user focused, tight iteration loop, really dog food at the thing, like mainline to the app as much as possible to get get everything right …”

“Think of it as like you're hiring Cursor or Cloud Code or Codex to be the engineer you delegate things to.”

“The thing to me that feels most psychologically inconsistent about myself is that I have for 20 years been using computers the same way. I now have A magic thing called codex. So do you, so does everybody. That means I should completely be using my computer in…”

“We just merged ChatGPT and Codex together.”

“But last year, for example, we killed Sora. Which was, you know, good product, and fun, and cool, but used a lot of compute, and not as important as Codex, where we put the compute.”

“Of all AI users, if you look at the percentage of people who are paid AI users, and if you look at the percentage of those who are using things like Codex or Cloud Code, it is minuscule. So already, if you're just trying to be in the top, like, one percent of …”

“Now, when you're doing this kind of end-to-end thing, you are less likely to get disrupted. In fact, if you know, if anything, if the if the cloud models or codex or even Gemini models or any of these other models get a lot better at coding, these people only …”

“In order to run multiple agents at once, your Mac has to manage each thread, right? So if you're running, you know, one, two, three, 10, 100 agents at the same time, whether they're running through Codex, Pi, OpenClaw, or whatever, you have to have memory and …”

“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 plugins or computer use or artifacts. You get that power regardless of what your…”

“The vision is like bring useful agents to everyone. We started with like developers Historically are like early adopters that are willing to put up with more friction, set things up, et cetera. Like that's where, you know, Codex started. I think the next oppor…”

“Like, I think we fully intend to like, you know, treat developer, like developers have been, you know, a core market for us for so long. And like, there's so much more that we can do to make Codex great specifically for software development, and we'll continue…”

“I think codex mostly Is winning because it's the best product and the best model. We do get some advantage from ChatGPT bundling, but very, very tiny. That is mostly not what it's been about.”

“Like, if you are, if your whole engineering you know, motion is happening inside of clock code or inside of codex, What are you doing? Like, because they are not incentivized to make it reasonable for you long term, right? They're going to lock you into their …”

“The new ChatGPT app is just the Codex app, and when you install it, you can keep the The old ChatGPT app as ChatGPT classic, but a lot of people don't like that because the Codex app is written in Electron, which means it's a bunch of like web views, web brows…”

“Codex with five, six, which I find to be the most usable, most powerful, fastest model for, specifically for knowledge work and for coding, but like specifically for knowledge work”

“In this world, you're just a SaaS provider. You're just hosting software. So there's no token costs. And so your margins are back to being like regular, a regular software business instead of being an AI business, which I think is great.”

“I would go to Claude for the actual design, and then port it back in here, because I still think that Claude has a better sense, especially Fable, RIP. But even, even four eight would be better at this. And I think for a product like this, being able to see it…”

“Like, one of the interesting things about Codex is it has this thing called Chronicle, which is it automatically takes screenshots of your computer and locally turns it into locally turns it into a, Feed that gives it context on who you are and what you're doi…”

“And the way it works is you can just you just start it by saying, can you just watch me do this? And it will record your screen as you do a task and then turn that automatically into a skill to do it in the future.”

“Not a single one of our full-time engineers right now writes code anymore. They do everything through Codex, Cloud Code, or Cursor.”

“Most people, even though it's easy, most people won't have a use case for sort of coding unless you move coding into like the more nebulous, like recipe idea, you know, sort of like Apple shortcuts or something where it's like, it is coding, but it's not reall…”

“We have software engineers who are completely AI-pilled and using Cloud Code, Codex, our own internal agent we call Pinecone that we used to run much of the company on, and they estimate they are between three and 20 times more productive in terms of features …”

“You can hook up, like I hook up my codecs to Slack, to my Gmail, to my calendar, and there are many people within OpenAI, non-technical users, you know, it's got code in the name, but it's not really about code. It's really about having this general purpose to…”

“Within OpenAI, we basically have the same level of penetration now and usage of slack. Right. It's like everyone in opening eyes like an entirely slack based company. We do not use email for the most part. It's like really like if you're not on slack, you're n…”

“And we had Codex actually get GPT-OSS running from scratch just based off of our docs completely by itself. And it did it, I think, overnight.”

“Like we have baby codex, right? A dramatically simplified code base that approximates all of the interactions of the production app. And therefore is a lot quicker to vibe code over, right?”

“There's been a lot written about role collapse, existential role collapse. There are no roles anymore. We haven't seen that. We've, we have seen more role collapse in the Codex org than I think other parts of the company and other parts of the economy.”

“There is a desire among all of us to try to do as much as possible in the app, even when it's not the best tool so that it can become the best tool. And so a lot of design we all work on by using the app and say, okay, what's broken about this? This is a whole…”

“We have people from marketing, from comms, from finance, from legal, from basically every discipline who are using this codex app, even though it is actively hostile to these people, right?”

“Codex is not a video editor per se, right? It doesn't have any of that UI in it. But it was able to understand that he used Premiere Pro. It could do some edits by editing the files that were backing what was on screen in Premiere Pro, but it couldn't do every…”

“We're trying to do two things at once with Codex and with now with ChatGPT. One is how can we seamlessly interact with these tools that you're already using and say, like, we don't need to build a better video editor for you. Right. But like Codex and ChatGPT …”

“Yeah, so we have an internal AI policy to make sure that we're only using enterprise account, that there's not sensitive things being uploaded, etc. I think that's really important. And then within those guidelines, most of our engineers are using cloud code a…”

“We have a really great dev info team. They built something called Isaac that's basically like a wrapper on cloud code and codex and let's you use them either on the web and like, Sandboxes or just on your dev machine or on your laptop or whatever.”

“And especially when there's the possibility of correlated failures, right? So it's not just that there's a lot of AI systems out there, it's that there's actually a few models that everyone is using. And if you find vulnerabilities in the agents that everyone …”

“I think that's why OpenAI is cutting codex pricing, simply because coding, you know, coding tokens are so valuable, and if you don't have enough of them, you may not be able to get into this RSI loop that, that everyone is, you know,”

“My prediction would be agents that are like completely autonomous software engineers. Today, I think we're all using Tools like CloudCode or Codex to write code, but not as literal software engineers.”

“Codex It does feel a little more technical than your lovable or your replet or your bolt. But if you can stay with it the output I think is super, super valuable.”

“Replit, if you have a complex feature, Replit builds it in Claude, Sonnet, not Open, it builds it in Sonnet to save money, and then it has Codex come in and check the work. It has both of them.”

“When we talk to the CIO, they know that their engineering teams are using cloud code and codex and cursor, and they're seeing the productivity gains come out of those teams.”

“OpenAI for a while was, I, in my opinion, like, very, very behind on this, and then in my opinion has surpassed them recently.”

“Whoever's in the lead, it feels very obvious to me that all of the work that you do is going to be in one of those surfaces”

“The Google anti-gravity team flashed a codex folder in their in their actual demo video.”

“In 2019, 20, 20 time GPT-II had just been trained. And that was, I think, one of the first language models that came together and was coherent over longer horizons. And there was a variant of GPT-II that that was called Codex. And this is kind of the same name…”

“Sam Altman today tweeted that enterprises who want to move to Codex can get their first two months of tokens free.”

“Cursor Codex by OpenAI and Copilot by Microsoft, they have all sold to the enterprises. But developers are not using them.”

“I would predict that most revenue is going to go be going to codex. That's my, I might be wrong, but just given how much money is going to Claude.”
