We write very, very few specs on the Codex team. We're talking like 10 bullets or something and that's it. The designers on the Codex team write more code now than was written by an engineer like six months ago.

And I made a quick prompt to create a little 2D game, maybe add

some more decorations, houses, trees and stuff.
B (0:17)
Could you add some more decoration like trees? And there we go. We have already new trees appearing for a small change.

It's often faster to send a PR than it is to communicate to someone and get them to prioritize that task when they have 10,000 other things to do. I don't actually view PM as a goog leadership position. I view it as a fill in the gaps position. I think the fewer people you need in a room to do anything, just the better that thing goes, the more pure every decision is.

Okay, welcome everyone. I'm really excited to host today. Alex and Roman from OpenAI's Codex team. They're going to demo how they build new features of Codex, what Codex is capable of, and also talk about how the Codex team ships nonstop. So welcome guys.
B (0:57)
Thank you. Thank you for having us.
A (0:59)
Yeah, excited to chat.
C (1:00)
So do you guys want to just quickly show what kind of things code can actually build in one shot?
B (1:05)
Yeah, for sure. I mean, let me share my screen to give you a sense. And so there's so much I could show, but maybe a quick glimpse into. For instance, Here is an iOS app I've been building and if I want to actually create a new feature for this app, I can simply dictate and voiceover something that says, hey, can you add a new screen for NASA's Artemis mission return to the moon? And I can send that prompt with GPT 5.4. And sure enough, the model will like create a new screen for this particular iPhone app. So here we have this app. It's pretty cool. And it's currently building this new feature, so we should see that in a moment. But we also have the Codec Spark model, which can really help you ideate and iterate in just a few seconds on. On anything. In fact, let me show you, like what it's working over here, the difference of what it does to have a Spark model responding so quickly. On the left side you have GPT 5.4, right? I'm going to give it a head start. And on the right side you have Codec Spark and boom, you have like 1200 a second on average. This is insane speed. And so when you want to build something, let's say a Game or right before we started this conversation, I actually went to the Codex app and I made a quick prompt to create behind the Crossing, a little like 2D game where I can start building. What also I love using with the Codex app when I'm in the flow is taking the Codex app like this and pop the conversation out on top of the screen, right? And so this way now what I can do is like if I'm like actually working on this game, I can keep iterating and have more ideas. I don't know what we want to do. Do you have an idea, Peter, for what you would like to change on this game?
