**Julian Goldie** (0:00)
GPT Codex One Hour Free Course. So today, you'll learn how to master 99% of codex in the space of 60 minutes. So I'm gonna walk you through exactly how to use it, how to get the most out of it, how to build and automate anything with it. We've actually tested it on literally hundreds of projects at this point, and with the new model from ChatGPT, which is GPT 5.6 Soul, this is their new frontier model. We've tested this across many different versions of different games, apps, tools, et cetera, and it can build some unbelievable things, right? So this is something that I've relentlessly tested, and I can tell you now that this is one of the most powerful tools that you can get access to, and Codex can basically help you automate and build anything. So today we're going to get straight into it. If you're not sure how to get Codex, how to get started, you can just download it from their website, so you download it from Mac OS. It has changed recently since GPT 5.6 Sol just dropped, and you can see an example of it over here. So this is what it's going to look like once you pull it up. You do need to log in once you've downloaded it, but basically this is what you're going to see as soon as you get started. And there's all sorts of amazing features with Codex. So for example, you can build websites, tools, games locally. You can get it to actually control your computer. You can get it to connect to all your favorite plugins. And with that, we're going to get straight into this. So what you'll see on the left hand side is that we've got everything that we're working on on the left hand side. Now, if you want to use the normal version of ChatGPT, not Codex inside the same app, then this is what they call a super app, and you have the chat over here. Now, this can pull in your conversations from your login on ChatGPT, but this is just literally the chat. So, inside this section, you go back and forth with ChatGPT, whereas with Codex, this is more for building big projects locally and building like automations that can run 24-7. So, to get started, really you need something that you have an idea for what you want to build. If you're not sure, I would just look at everything that you work on day to day and be like, right, we need to build this, so we need to build that, we need to start working on this. So, let me show you an example of this, right? So, and let's say for example, we wanted to build a website that could essentially replace everything that I have in my SEO agency, and then people could order online, right? So, it's like a, it's a website that's kind of like e-com for my agency, and people can just order online via that website and start ordering SEO from our set. So, we can start from scratch, and I'm going to call this SEO agency e-com store website, just as an example to show you, and then we are going to hit save like so. And now, we can choose between whether we're going to build locally or whether we're going to build in the cloud, and also whether we're going to fork the conversation. So, let me explain what this means. So, you see here we've got the project folder. So, it says SEO agency e-com store. This is the project that we are working inside to build out our automation. So, we want to have this stored inside a folder, so it's neat and tidy and easy to come back to. If you want to have a look at any of our other projects, so for example, like a daily GMO automation, agent operating system that we're building recently, your template set up, habit tracker, et cetera, we can just scroll through this list. But if you're starting from scratch, just create a new folder. Now, you can choose whether you want to do it locally or in the cloud. Cloud is great for an environment where you need stuff to be sandboxed away. So, what that means essentially is like you would have your agent working in cloud doing something else and it's not like connected to your local setup at all. It's not connected to your computer at all. But, if you want all of your files to be available on your laptop, on your computer, on your Mac, whatever you're doing, then you want to work locally. I think it's more useful to do that because then you can come back to the files. You've got them all ready. If we wanted to start using cloud with the same project, we could just switch up to cloud and open up the same project there. We could have multiple different agents working on the same project. I do think the local is better in general. But if it's like something where you need maybe a super secure setup, then cloud is better because that way it doesn't interact with anything or any files you got locally. Now you also see here that you have the usage remaining section. This just allows you to figure out, okay, how much usage do you have left? How many tokens do you have left? What percentage of your plan have you used up? And a real battle with new models, especially since GPT 5.6 Soul came out, is that these frontier models are unbelievable, very, very powerful. They can create most of the stuff. Biggest issue with that is that they're expensive to run. And so now we have more problems with token usage, which means that we have to be efficient with our setup. And I'll come up with more ways you can optimize that later. And we can always upgrade our package over here if we want to. So from here, we're gonna get started. Now, what you're gonna do from here is you are going to click inside the do anything section. And if you have like anything that you want to switch between or anything that you want to set up here, you can see that we can click on the plus side. So if you have like a logo we want to use, you could upload a file and folder. If you have an existing piece of code that you need to change, then you can plug that in. And you can also attach Claw to this. You could have goal mode running, you can have plan mode, etc. We'll come on to what those means. We can also add plugins inside there so we can connect to different apps, even like Spotify we can connect to. And then we have our apps and plugin management over here. So I'm gonna start with the basics. And what we're gonna do is we want to plan our project first. The reason that you want to plan your project before you go into building it, is that it's been proven with research, Kilo Code actually did a research plan on this. And they found that if you plan ahead first, you'll get better outputs because all the decisions are made when it comes to building. Whereas if you have lots of decisions that need to be made later, the AI agent can go off track if you make bad decisions, you can get lost in the context. So it's better to start generating a plan first. So I'm going to say inside the chat here. Can you come up with a plan to build out an SEO agency website for Goldie agency? And basically what it's going to allow people to do is you're going to productize my packages that have for SEO and you're going to basically set those up as a web page where people can order online. So I need you to plan out every element of it. I want to give you my brand colors and everything else, my logo and also the key links as well, so that you can use all this, that will be built out.
