What you can do is if you have a code base that you're operating against, you're building a new feature in a code base or debugging something, you can just give this agent the prompt like, hey, I need you to fix this thing.

I want you to do this to the background of my web page.

I want you to build this new feature.

And it will go and look through your entire code base, understand all of the context.

If you're fixing a bug, it'll go try and figure out where that bug exists.

And then it will write new code for you and create a pull request, like a diff.

Here's the set of changes we need to make to the code.

And then you can go review the code.

And the agent did the whole thing.

And so, you know, I used to be an engineer.

I still write code a little bit in my spare time, but I haven't written a single, you know, line of code for OpenAI.

But with Codex, I was, this was like, you know, a few days before it launched.

I was, you know, I was like 11 at night or something.

I was doing a bunch of work that I had to do before I could go to bed.

And I was like, you know what, I bet I could fix a bug right now.

And so went and found a bug that looked relatively simple and just pasted the context into Codex, said, can you go off and fix this bug?

By the way, it was in a language that I had actually never worked with in my life.

So it would have taken me even more time if I had to do it myself.

And 10 minutes later, I had a pull request.

It looked reasonable.
