Verbatim, from the transcripts: the passages where Codex comes up
OpenAI’s Vision for the AI Super App — Akshay Nathan, OpenAI
- ▶ 3:09 unnamed speaker So ChatGPT, CodexApp, ChatGPT for work.
- ▶ 13:57 Akshay Nathan Like what is, you know, Codex obviously people love, like why, why bring these products together? 4 times in the scene
The AI Frontier: from open weights to open research — Eiso Kant, Poolside AI
- ▶ 1:00:24 unnamed speaker So open code, codex, you have your own pool CLI tool, um, basically getting people to use it, the co-design of model harness, training it in.
When AI Agents Run Businesses — Lukas Petersson and Axel Backlund of Andon Labs
- ▶ 32:11 unnamed speaker But today somebody could just spin up a Shopify cloud store, give it to cloud, give it to Codex.
Devin’s 80% Moment: Background Agents, 7x PRs, & End of Hand-Held Coding — Walden Yan & Cole Murray
- ▶ 41:59 unnamed speaker Um, have you seen, did you see the Codex app? 2 times in the scene
Extreme Harness Engineering: 1M LOC, 1B toks/day, 0% human code or review — Ryan Lopopolo, OpenAI
- ▶ 4:40 Ryan Lopopolo Started with some of the very first versions of Codex CLI with the Codex mini model, which was obviously much less capable than the ones we have today, which was also a very good constraint, right?
- ▶ 4:40 Ryan Lopopolo Started with some of the very first versions of Codex CLI with the Codex mini model, which was obviously much less capable than the ones we have today, which was also a very good constraint, right?
- ▶ 5:55 Ryan Lopopolo Um, one interesting thing here is five two, the codex harness at the time did not have background shells in it, which means we were able to rely on blocking scripts to perform long horizon work.
- ▶ 15:12 Ryan Lopopolo Um, when we first started adding code review agents to the PR, it would be Codex CLI locally writes the change, pushes up a PR.
- ▶ 18:29 unnamed speaker So it's codex level coding and reasoning. 3 times in the scene
- ▶ 29:07 Ryan Lopopolo One other neat thing about this too, is when we deploy Codex security on the repo, it is able to deeply review and change
- ▶ 32:34 Ryan Lopopolo Ask codex with our repo as a reference. 3 times in the scene
- ▶ 1:00:50 unnamed speaker Like Codex is really good at code base understanding, working with code bases, but companies like Lovable, Bolt, Replit, they solve a very different problem scaffold of zero to one, right?
Agent Inference at the "Speed of Light" — How NVIDIA moves like a $4.3 Trillion Startup
- ▶ 49:05 Shawn Wang Yes, I mean, that's, that's effectively what's happening with Codex.
Cursor's Third Era: Cloud Agents — ft. Sam Whitmore, Jonas Nelle, Cursor
- ▶ 9:19 Jonas Nelle I think we found in particular with Opus four, five, four, six and codex five, three, that those were additional step changes and sort of the autonomy grade capabilities of the model to just go off and figure out the details and come back…
- ▶ 38:56 unnamed speaker Sure, it's codex high today, but like, do I care if it's suddenly switched to Opus? 2 times in the scene
Claude Code for Finance + The Global Memory Shortage: Doug O'Laughlin, SemiAnalysis
- ▶ 16:08 Doug O'Laughlin Oh, I also tried Codex, too, before this, like, uh, like when it was 5.2, never really got it to work in the way, seamlessly, agentically. 2 times in the scene
Brex’s AI Hail Mary — With CTO James Reggio (acquired for $5B by Capital One!)
- ▶ 36:02 Shawn Wang Yeah, what we hear from, like, the Gen Z's at OpenAI, they, they just YOLO everything into Codesk.
[State of Post-Training] From GPT-4.1 to 5.1: RLVR, Agent & Token Efficiency — Josh McGrath, OpenAI
- ▶ 5:17 Josh McGrath Um, and the same thing happens with Codex, right?
⚡️GPT5-Codex-Max: Training Agents with Personality, Tools & Trust — Brian Fioca + Bill Chen, OpenAI
- ▶ 1:21 unnamed speaker Uh, so you guys, I guess, are representing, like, the startups team, Codex. 3 times in the scene
- ▶ 1:42 unnamed speaker Why call it Max? 3 times in the scene
- ▶ 12:08 Bill Chen As I said, um, we train our models are starting to be a little bit more opinionated, especially with regard to Boeing model, uh, like Codex. 5 times in the scene
- ▶ 14:47 Brian Fioca I mean, Codex Max was designed for that, right? 3 times in the scene
Terminal-Bench 2.0: the most impt coding agent benchmark of 2025 gets a v2! Launch + Q&A w/ founders
- ▶ 6:04 Mike Merrill We see codecs with GPT-V ranks at the top of the benchmark in our testing.
Amp: The Emperor Has No Clothes
- ▶ 12:50 Alessio Fanelli Now you had codec CLI, which is trying to catch up.
- ▶ 29:06 Alessio Fanelli Is the GPT-V codex only being available in codex making you nervous about future availability of, like, cutting-edge models, and, like, does that put more emphasis in, like, figuring out maybe, like, an open source strategy? 2 times in the scene
⚡️Warp 2.0: the Agentic Development Environment - Zach Lloyd and Ben Holmes
- ▶ 16:39 Zach Lloyd So what's cool about warp compared to, say, Cloud Code or Ader or Codex CLI is that as you do this sort of like linear agent-based coding workflow, you can actually use like some elements of rich UI to do it.
ChatGPT Codex: The Missing Manual
- ▶ 4:16 Alexander Embiricos So a lot of those, those learnings ended up becoming the Codex CLI, which shipped recently.
- ▶ 8:42 unnamed speaker And talking about form factor, so you mentioned the CLI, which you already released, and I think there's other, you know, Cloud Code, AIDR, a bunch of other tools out there. 2 times in the scene
- ▶ 16:06 Josh Ma Well, actually, these days I'm using code one to do it, because it can traverse, uh, codex one, sorry, to traverse, like, your directory tree and generate those things for, for you. 4 times in the scene
- ▶ 24:45 Alexander Embiricos And we, we just think it kind of sucks if you have to, like, create, like, all these different agents and whatever, you know, so, like, part of why we made the Codex CLI open source is, like, a lot of problems, like, safety issues that you…
- ▶ 45:48 Josh Ma Like, you know, I love using Codex CLI, um, and, uh, it's really, we just want, like, as we talked about in our interview, when I was interviewing OpenAI, like, you really want both modes, um,
