WEBVTT 00:00:00.266 --> 00:00:02.266 This video will teach you Codex. 00:00:02.266 --> 00:00:07.533 I'll go through all of the important features, show you how to set it up and install it, and assume no prior knowledge. 00:00:07.533 --> 00:00:10.533 So even if you're a complete beginner, you'll be able to follow along. 00:00:10.600 --> 00:00:14.266 Now I'm going to be covering things like computer use or browser control. 00:00:14.266 --> 00:00:22.966 I'm going to show you how to set it up for coding model selection, all of the different commands like slash goal, and a lot of the new features that I haven't seen many people cover. 00:00:23.000 --> 00:00:24.700 So with that said, stick around. 00:00:24.700 --> 00:00:27.133 Let's get into it and let me teach you Codex. 00:00:27.133 --> 00:00:29.333 So let's start by discussing what Codex is. 00:00:29.333 --> 00:00:32.433 We'll look at how we can use it because there's actually many different ways. 00:00:32.433 --> 00:00:34.833 And then I'll start going through all of the different features. 00:00:34.833 --> 00:00:37.533 There'll be timestamps down below in case you want to skip forward. 00:00:37.533 --> 00:00:40.433 And keep in mind I like to make things really thorough in detailed. 00:00:40.433 --> 00:00:44.400 So if you feel like I'm going to slow, fast forward to the next section okay. 00:00:44.433 --> 00:00:46.266 So first what is Codex? 00:00:46.266 --> 00:00:50.533 Well Codex is essentially OpenAI's answer to tools like Claude code. 00:00:50.533 --> 00:00:57.266 It's actually much more involved than Claude code I would say it has a lot more features, and a lot of people don't know about what you can do with it. 00:00:57.266 --> 00:01:03.700 Now, the basics is that you can use it to write code because it will give you access to their top models like GPT 5.5. 00:01:03.733 --> 00:01:10.500 However, you can also use it to control your computer, to automate tasks, to perform something repetitive for you. 00:01:10.500 --> 00:01:14.000 And you can even do something like tell it to play a song on Spotify for you. 00:01:14.000 --> 00:01:17.000 And it can go and do that by controlling your computer. 00:01:17.000 --> 00:01:19.700 So there's a lot of cool features that are not just related to coding. 00:01:19.700 --> 00:01:22.100 I'm going to try to cover all of those in this video. 00:01:22.100 --> 00:01:26.900 So what I want to do is quickly cover how you can use Codex, because there's a lot of different ways. 00:01:26.900 --> 00:01:33.600 And OpenAI has been very confusing with the naming of Codex because they had models called Codex like their actual LLMs. 00:01:33.600 --> 00:01:38.466 Now they have the tool called Codex, and you can use it in like many different fashions. 00:01:38.466 --> 00:01:42.866 So for this video we're going to be using the stand alone desktop application. 00:01:42.900 --> 00:01:45.833 The way this works is you download it and install it on your computer. 00:01:45.833 --> 00:01:49.133 You can get it for windows, Mac and then they don't have it for Linux right now. 00:01:49.133 --> 00:01:50.400 So just Windows or Mac. 00:01:50.400 --> 00:01:53.666 Now you'll sign into this using your ChatGPT subscription. 00:01:53.666 --> 00:01:57.133 You can use it, I believe, as low as $20 per month on the plus plan. 00:01:57.133 --> 00:02:02.400 Just keep in mind I do have the $200 per month plan, so my usage limits will be significantly higher. 00:02:02.433 --> 00:02:04.400 Now the limits are typically very generous. 00:02:04.400 --> 00:02:07.300 You're probably going to get 5 or 10 times the amount of usage. 00:02:07.300 --> 00:02:11.933 Then you would compare it to something like Claude Code, so I wouldn't be too concerned with ripping through it. 00:02:11.933 --> 00:02:15.266 Unless you use the highest end models and you're running it 24 over seven. 00:02:15.266 --> 00:02:17.666 Now you can also use this with an OpenAI API key. 00:02:17.666 --> 00:02:21.100 I definitely do not recommend that because that's going to be very expensive. 00:02:21.100 --> 00:02:33.066 So first up, if you don't want to be downloaded and installed Codex, I'll leave a link to it in the description sign in with your ChatGPT account, then you're good to go now as well as the desktop app, which again is what we're going to be using. 00:02:33.100 --> 00:02:35.033 They also have an IDE extension. 00:02:35.033 --> 00:02:43.100 You can install this in the popular editors like cursor, Visual Studio Code and Windsurf and have access to the same Codex interface inside of that editor. 00:02:43.100 --> 00:02:45.000 If you're a developer, you may want to do that. 00:02:45.000 --> 00:02:46.400 We also have CLI. 00:02:46.400 --> 00:02:54.000 Now this is a command line interface more familiar to something like cloud Code, where you're not in kind of a nice graphical user interface, which you'll see in a minute. 00:02:54.000 --> 00:03:00.866 But the advantage here is that you can run this on something like Linux or a server, and you can have this as a remote machine that's running 24 over seven. 00:03:00.900 --> 00:03:01.299 Same thing. 00:03:01.299 --> 00:03:02.533 You can sign in with your account. 00:03:02.533 --> 00:03:06.233 And then we have the cloud version which is running directly in your browser. 00:03:06.233 --> 00:03:12.266 It's better if you can use the desktop version, but if you want to do it from the browser on your phone or something, you can do that. 00:03:12.300 --> 00:03:14.500 Okay, so those are the surfaces for Codex. 00:03:14.500 --> 00:03:19.066 Again, what we want to do is download the desktop application, which is where we're going to be working. 00:03:19.066 --> 00:03:20.666 And now let's open up that app. 00:03:20.666 --> 00:03:27.833 So just open up the desktop application, which is where we're going to be working and where I recommend you use Codex because does the most number of features. 00:03:27.866 --> 00:03:29.866 Now let's start by going through the user interface. 00:03:29.866 --> 00:03:32.800 You can understand what all of these buttons actually do. 00:03:32.800 --> 00:03:35.066 And then I promise we'll go through all of the features. 00:03:35.066 --> 00:03:37.066 So here you have your main chat window. 00:03:37.066 --> 00:03:44.233 There's a few things you want to pay attention to, like the model selector which we'll look at in a minute, the voice dictation in case you want to use that the approval modes. 00:03:44.233 --> 00:03:47.000 So ask for approval approved for me or full access. 00:03:47.000 --> 00:03:50.100 And then being able to add different skills context. 00:03:50.100 --> 00:03:53.733 And then if you want you can actually run commands by using this slash. 00:03:53.833 --> 00:03:58.066 So if you do forward slash you be able to see a list of all of this stuff available which will be going through. 00:03:58.100 --> 00:04:01.466 You also have the ability to organize different chats into projects. 00:04:01.466 --> 00:04:03.333 So you can see I have a few projects here. 00:04:03.333 --> 00:04:05.933 You can make a new one, but we'll look at that in a few minutes. 00:04:05.933 --> 00:04:09.600 Now from the right hand side you'll also notice that you have these toggle bars. 00:04:09.600 --> 00:04:12.833 So if you click on the right it's going to show you a browser and a terminal. 00:04:12.833 --> 00:04:17.600 That's because Codex can automatically control a browser for you and test your applications. 00:04:17.600 --> 00:04:23.233 And then you can also toggle up the terminal or the shell, which again Codex can control and use for you. 00:04:23.266 --> 00:04:27.533 You typically don't need to do this, but I'm just showing you those views exist from the left hand side. 00:04:27.533 --> 00:04:32.900 You can also toggle this sidebar where you have some of the important I don't know, buttons or views. 00:04:33.166 --> 00:04:36.433 If you want to access the settings menu, you can click on your profile. 00:04:36.433 --> 00:04:39.433 You can go to profile or to settings for settings. 00:04:39.433 --> 00:04:43.500 If you are someone who's not going to do any coding, you can switch this over to the everyday work mode. 00:04:43.500 --> 00:04:50.200 So it's going to be a little bit less technical, but for most of us, we're going to want to stay here where we have access the browser, the terminal and some other features. 00:04:50.233 --> 00:04:51.433 There's a ton of settings. 00:04:51.433 --> 00:04:54.266 Feel free to look through these and change any of them if you want. 00:04:54.266 --> 00:04:56.233 But again, I'll go through them one by one. 00:04:56.233 --> 00:05:03.733 And then last thing, if you go and look at usage and billing, you'll be able to see your usage, the plan that you're currently on, if you have any balance or anything. 00:05:03.733 --> 00:05:05.833 Again, these are very generous limits. 00:05:05.833 --> 00:05:09.666 It's very unlikely that you're going to hit them, especially if you're doing something somewhat normal. 00:05:09.666 --> 00:05:11.433 So I wouldn't stress out about it too much. 00:05:11.433 --> 00:05:13.933 Okay, so now that we've gone through that, let's start looking at the models. 00:05:13.933 --> 00:05:20.200 Let's start running a few chats and setting up some plugins so I can show you things like the computer control, which is super cool. 00:05:20.200 --> 00:05:24.266 But first, just a quick word from our sponsor boot dev. 00:05:24.300 --> 00:05:29.400 Now this is one of the best learning platforms out there and actually a long term partner of this channel. 00:05:29.400 --> 00:05:33.266 Now, one of the biggest problems that I see with people learning to code is boredom. 00:05:33.266 --> 00:05:38.333 They watch tutorials, copy code, feel productive for a week, and then they quit now. 00:05:38.333 --> 00:05:40.900 But dev takes a completely different approach. 00:05:40.900 --> 00:05:45.066 It's very hands on and honestly, it feels more like a game than a course. 00:05:45.100 --> 00:05:50.066 Now you're learning backend development by actually building things, not just watching videos. 00:05:50.066 --> 00:05:58.000 You work through real challenges in Python SQL and go earn level up five bosses and progress through a full backend curriculum. 00:05:58.000 --> 00:06:04.266 Now it sounds a bit gimmicky, but I promise you it actually works because you're doing the same kind of problem solving that you do on the job. 00:06:04.266 --> 00:06:14.833 Now they also have an AI tutor called boots, which doesn't just dump answers on you, it asks follow up questions and helps you reason through problems when you get stuck, which is way closer to how you actually learn. 00:06:14.833 --> 00:06:22.933 Now, all of the content is free to read and watch, and if you want the interactive coding, the progress tracking, and the AI assistance, that's part of the paid plan. 00:06:23.000 --> 00:06:29.233 If you want to check it out, go to dev and use my code tech with Tim to get 25% off your first year. 00:06:29.266 --> 00:06:31.633 Big thanks to Boot Dev for sponsoring this video. 00:06:31.633 --> 00:06:33.266 Now let's get back into it. 00:06:33.266 --> 00:06:35.933 So like I was saying, let's have a look at the model selection. 00:06:35.933 --> 00:06:37.400 Now, for some reason you don't see this view. 00:06:37.400 --> 00:06:40.300 You can always just press a new chat and it will bring this up. 00:06:40.300 --> 00:06:47.033 Now from here if you go to model selector you're going to see that you have a reasoning level light medium high and extra high. 00:06:47.066 --> 00:06:54.066 Now of course you want to use the best reasoning whenever you possibly can, but keep in mind that this is going to take significantly longer. 00:06:54.066 --> 00:06:58.100 So the reasoning can kind of come down to how long this is going to take. 00:06:58.133 --> 00:07:06.633 Of course, the higher reasoning, the better responses and results that you're typically going to get, but it can increase the time by like 4 or 5, sometimes ten x. 00:07:06.633 --> 00:07:10.800 I've had tasks here taken 30 minutes to run in extra high reasonings. 00:07:10.800 --> 00:07:11.833 If you want something fast. 00:07:11.833 --> 00:07:17.333 If you're asking a quick question, you don't need super high reasoning and you can put this in light or medium mode. 00:07:17.400 --> 00:07:20.333 Now, when it comes to the model itself, you have a few options. 00:07:20.333 --> 00:07:23.333 GPT 5.5 is kind of the best one. 00:07:23.333 --> 00:07:27.500 The frontier coding model, the one you're going to want to use for pretty much everything. 00:07:27.533 --> 00:07:32.400 GPT 5.4 is just the generation before that that has kind of cheaper usage limits. 00:07:32.400 --> 00:07:34.627 I would never use this one. 00:07:34.627 --> 00:07:35.700 GPT 5.4 mini. 00:07:35.733 --> 00:07:42.400 This can be used for small, fast, kind of efficient things where you're asking a question or you just want, you know, quick UI change or something. 00:07:42.400 --> 00:07:50.200 And then 5.3 Codec Spark is just an extremely fast model that you use again, for very minor things that don't require a lot of intelligence. 00:07:50.200 --> 00:07:54.133 And specifically when you're running out of the usage on GPT 5.5. 00:07:54.133 --> 00:07:57.600 So for 99% of you, you just keep GPT 5.5 on. 00:07:57.600 --> 00:07:59.533 Probably throw it in medium reasoning. 00:07:59.533 --> 00:08:02.933 If you have enough credits, you can turn on this fast mode so it'll run faster. 00:08:02.933 --> 00:08:08.700 I pretty much always leave that on, and then if you start running out of the usage, you can switch to some of these other models. 00:08:08.700 --> 00:08:14.300 You can change the speed back to default and you can adjust the reasoning, but most of the time 5.5 medium. 00:08:14.300 --> 00:08:15.633 This is what you're going to keep it in. 00:08:15.633 --> 00:08:20.666 And if you're doing something more complicated, switch up the reasoning level here to high or extra high. 00:08:20.700 --> 00:08:23.400 You can play around with it, but that's pretty much all you need to know. 00:08:23.400 --> 00:08:26.066 Okay, so of course we're going to use this and I'm going to show you a bunch of prompts. 00:08:26.066 --> 00:08:30.433 But I want to show you how to set this up so we can do some really interesting things with Codex. 00:08:30.433 --> 00:08:33.033 So what we're going to do here is go to plugins. 00:08:33.033 --> 00:08:37.833 Now this is one of my favorite features of Codex is all of the plugins that it has by default. 00:08:37.833 --> 00:08:47.066 And the fact that it can control your computer, control your browser, control spreadsheets, access Google Drive, and do this in a really interactive and intuitive way. 00:08:47.100 --> 00:08:54.866 Now, most of your tools like this like cloud code, they can do the same thing, but I find Codex performs a lot better and it's just way easier to understand. 00:08:54.866 --> 00:09:00.533 So what we're going to want to do here is go to plugins and start installing some of the ones that you see on my computer right now. 00:09:00.533 --> 00:09:02.666 So the first one is computer use. 00:09:02.666 --> 00:09:05.700 If you don't already have this installed, you can install it and activate it. 00:09:05.700 --> 00:09:07.466 It may ask for some permissions here. 00:09:07.466 --> 00:09:09.933 And this is going to allow you to control your computer. 00:09:09.933 --> 00:09:14.466 So you can tell it to open up an application go to your browser, access Spotify. 00:09:14.500 --> 00:09:16.233 We're going to look at that in one second. 00:09:16.233 --> 00:09:18.333 Next plug in we're going to want is Chrome. 00:09:18.333 --> 00:09:20.466 So we're going to want to install this Chrome plug in here. 00:09:20.466 --> 00:09:23.333 And then open up this Chrome extension okay. 00:09:23.333 --> 00:09:24.600 This Codex Chrome extension. 00:09:24.600 --> 00:09:26.600 You can see I already have mine installed here. 00:09:26.600 --> 00:09:29.900 And if I go to the view you can see we have Codex and it's connected. 00:09:29.900 --> 00:09:32.533 And this will allow Codex to control your browser. 00:09:32.533 --> 00:09:33.633 So it can open up a tab. 00:09:33.633 --> 00:09:34.921 It can search for something. 00:09:34.921 --> 00:09:36.300 It can debug your application. 00:09:36.300 --> 00:09:37.866 Make sure that you get that set up again. 00:09:37.866 --> 00:09:41.400 If you just press this open button you can install the extension and link it. 00:09:41.433 --> 00:09:44.300 Another extension that I highly recommend is GitHub. 00:09:44.300 --> 00:09:49.400 If you're unfamiliar with git and GitHub, this is essentially a version control software for code. 00:09:49.433 --> 00:09:53.866 This means that you can save your changes, that you can recover them later on. 00:09:53.900 --> 00:09:58.333 You can store them in the clouds, you can use them from a different device and you can share them with your teammates. 00:09:58.400 --> 00:10:02.033 This is a standard anytime you're building even a medium sized project. 00:10:02.033 --> 00:10:04.633 Really any type of coding project, you should be using this. 00:10:04.633 --> 00:10:06.866 So create a free GitHub account. 00:10:06.866 --> 00:10:07.400 Very easy. 00:10:07.400 --> 00:10:11.833 You can just go to github.com and then you can connect your GitHub account here inside of Codex. 00:10:11.833 --> 00:10:18.933 So it can automatically make what's called a repository, which is just storing your code effectively and upload it to the clouds that you're not going to lose it. 00:10:18.933 --> 00:10:23.300 You can access it from other devices and you can revert back in case Codex makes a change. 00:10:23.333 --> 00:10:25.800 It breaks whatever the version of your project is. 00:10:25.800 --> 00:10:35.533 I'm not going to be teaching git in GitHub too much, but I do highly recommend that you set up that plugin and you can see we have a few other ones here like Google Drive, presentations, spreadsheets, slack, Gmail. 00:10:35.533 --> 00:10:38.900 You can add as many of these as you want, but I'm going to stick with these for right now. 00:10:38.900 --> 00:10:43.300 So now that we have the computer plugin installed, I want to show you how to use this. 00:10:43.300 --> 00:10:50.666 So if I go and I use this at symbol, you can see that I can actually reference different applications and specifically this computer. 00:10:50.700 --> 00:10:51.066 Right. 00:10:51.066 --> 00:10:54.400 So from computer what I can do is ask it to do something. 00:10:54.666 --> 00:10:56.900 So let's start by doing something simple. 00:10:56.900 --> 00:11:05.266 Open up notepad, close any of the existing windows that are there, and then write a simple note and describe your ideal day. 00:11:05.266 --> 00:11:07.933 I know you're a computer, but just come up with something, okay? 00:11:07.933 --> 00:11:09.833 I'm just giving it kind of random prompt. 00:11:09.833 --> 00:11:14.233 By the way, if you're wondering what I'm using to prompt here, I always use this tool called Whisper Flow. 00:11:14.400 --> 00:11:17.200 Very good for voice dictation, especially in AI tools. 00:11:17.200 --> 00:11:18.585 I'll leave a link to it so you can check it out. 00:11:18.585 --> 00:11:19.133 In the description. 00:11:19.133 --> 00:11:21.933 You can see that I use it a ton based on my usage. 00:11:21.933 --> 00:11:23.733 Very very good and free to try out. 00:11:23.733 --> 00:11:27.100 Okay, so let's run this and let's see what we get here. 00:11:27.100 --> 00:11:29.233 And you can see that it's going to use the computer plugin. 00:11:29.233 --> 00:11:31.233 And it should control my computer. 00:11:31.233 --> 00:11:36.233 And keep in mind that while it's controlling my computer, I can still use the computer myself. 00:11:36.233 --> 00:11:38.027 So I can navigate into an application. 00:11:38.027 --> 00:11:39.066 I can close something. 00:11:39.066 --> 00:11:44.033 I don't need to have it kind of freely using the mouse, because it will actually use its own cursor. 00:11:44.033 --> 00:11:49.033 Okay, apologies, because it had a note there that I didn't want you guys to see, so I had to kind of rerun this. 00:11:49.033 --> 00:11:54.600 But you can see that it actually just opened up my computer here, open up notepad and wrote this note inside for me. 00:11:54.633 --> 00:11:54.833 Okay. 00:11:54.833 --> 00:11:59.514 So now if I want to say something, can you continue this node and make it like double or triple the length? 00:11:59.514 --> 00:12:00.600 Don't worry if it's unsaved. 00:12:00.600 --> 00:12:01.833 Just keep writing okay. 00:12:01.833 --> 00:12:02.700 And let's hit enter. 00:12:02.700 --> 00:12:06.333 And again you'll see that we kind of get that blue hue around our computer. 00:12:06.333 --> 00:12:17.100 And it's able to take over and do anything that we want, which can be super useful, especially for automating, kind of like testing a website, going through a form, running a task repetitively. 00:12:17.100 --> 00:12:17.866 You get the idea. 00:12:17.866 --> 00:12:18.942 So let's see how it works. 00:12:18.942 --> 00:12:20.433 And you can see that just opened it. 00:12:20.433 --> 00:12:22.233 And then did it extend the note? 00:12:22.233 --> 00:12:26.033 I guess not, says thinking okay, maybe it will take over again in a second. 00:12:26.200 --> 00:12:29.600 But when it does that you also see it's kind of cursor appearing, which I think is pretty cool. 00:12:29.633 --> 00:12:31.833 Okay, so for some reason it didn't keep controlling the note. 00:12:31.833 --> 00:12:33.266 But let's just do another example here. 00:12:33.266 --> 00:12:40.133 I'm going to say computer, open up Spotify, find Drake's most popular song, and then tell me what it is and play it okay. 00:12:40.200 --> 00:12:42.733 And let's just do this as an example so we can see okay. 00:12:42.733 --> 00:12:45.500 So it actually found that Spotify wasn't installed on my computer. 00:12:45.500 --> 00:12:48.266 And it's going to now do this from Chrome which is what I was trying to show. 00:12:48.266 --> 00:12:51.400 So I'm going to allow this to access my Chrome browser okay. 00:12:51.433 --> 00:12:56.833 So we can see it opened this, it actually started playing the song, I just paused, I don't want to get the copyright strike and it found the song for me. 00:12:56.833 --> 00:12:59.500 And then if I go here it says that this is the most popular one. 00:12:59.500 --> 00:13:01.733 Okay, I don't know if that's true, but at least that's what it gave us. 00:13:01.733 --> 00:13:04.933 So the point is it can control Chrome, it can control its own devices. 00:13:04.933 --> 00:13:05.700 So keep that in mind. 00:13:05.700 --> 00:13:06.666 That's super useful. 00:13:06.666 --> 00:13:09.800 But now let's move to some more coding related features okay. 00:13:09.833 --> 00:13:14.533 So if we're done with the current chat here, what we can do is just press new chat and open up a new one here. 00:13:14.533 --> 00:13:18.066 And what I'm going to do now is I'm actually going to create a new project. 00:13:18.066 --> 00:13:21.033 Now, whenever you're coding, I recommend that you make a new projects. 00:13:21.033 --> 00:13:26.333 You can organize all of your chats for that specific project, and you can go back and find them easily. 00:13:26.400 --> 00:13:29.100 It's not required to do this, but it's kind of a good practice. 00:13:29.100 --> 00:13:30.933 So you can see that I can make new project. 00:13:30.933 --> 00:13:32.700 I can use an existing folder. 00:13:32.700 --> 00:13:35.466 So maybe I have an existing code repo that I want to use. 00:13:35.466 --> 00:13:36.266 I can open that up. 00:13:36.266 --> 00:13:38.133 And that's kind of what a project is. 00:13:38.133 --> 00:13:40.233 It's really just a folder on your computer. 00:13:40.233 --> 00:13:41.866 Or I can start one from scratch. 00:13:41.866 --> 00:13:45.633 So I'm going to start one from scratch, and I'm just going to call this I don't know chess game. 00:13:45.633 --> 00:13:50.033 And what we'll do is we'll try to make like an interactive chess game here using Codex. 00:13:50.033 --> 00:13:52.066 So you can see that it's made a new project for me. 00:13:52.066 --> 00:13:53.333 It's called Chess Game. 00:13:53.333 --> 00:13:56.233 And notice that we have a few options here for the project. 00:13:56.233 --> 00:13:59.400 Now I have the ability to connect to Codex Web. 00:13:59.400 --> 00:14:04.500 This would essentially send all of the kind of info to the cloud, which is a little bit more complicated. 00:14:04.533 --> 00:14:09.033 We can work locally, which just means we're working on our own computer, which is what we're going to do here. 00:14:09.033 --> 00:14:11.133 Or we can create something called a work tree. 00:14:11.133 --> 00:14:19.500 Now we're going to look at work trees later, but essentially this is a clone of this kind of project so that we can work on multiple things at the same time without having a conflict. 00:14:19.500 --> 00:14:22.700 So for now, we're going to leave it in the current location that it's in. 00:14:22.733 --> 00:14:25.466 You'll notice that it automatically is connecting to get. 00:14:25.466 --> 00:14:27.466 So it's created a branch called main. 00:14:27.466 --> 00:14:30.466 And you can make different branches if you're familiar with git. 00:14:30.466 --> 00:14:31.800 But we're not going to look at that for right now. 00:14:31.800 --> 00:14:35.533 I'm also just going to move this to full access mode, just so I don't need to keep approving things. 00:14:35.533 --> 00:14:38.200 And you can see it's pretty straightforward what you do here with those. 00:14:38.200 --> 00:14:40.000 So now let me give this a simple prompt. 00:14:40.000 --> 00:14:42.000 I want to create a simple chess game. 00:14:42.000 --> 00:14:50.200 I want to have a back end which is using WebSockets and kind of keeping track of scores and ratings and stuff in a database in people's usernames. 00:14:50.200 --> 00:14:53.200 And then I want to have a front end where we can actually play this. 00:14:53.200 --> 00:14:57.266 I want it to be multiplayer, so I want two people to be able to play against each other. 00:14:57.300 --> 00:15:01.500 We can keep it simple, have an MVP to start and then build everything out. 00:15:01.533 --> 00:15:01.666 Okay. 00:15:01.666 --> 00:15:04.833 So I'm just giving it kind of, you know, prompt on what I, what it is that I want it to do. 00:15:04.833 --> 00:15:06.433 I want it to build something out here. 00:15:06.433 --> 00:15:08.266 And we're going to go ahead and press enter. 00:15:08.266 --> 00:15:10.066 And I just want to show you how this works okay. 00:15:10.066 --> 00:15:12.200 So we can see here the Codex is now working. 00:15:12.200 --> 00:15:13.466 It's making multiple files. 00:15:13.466 --> 00:15:14.733 We can see what it's doing. 00:15:14.733 --> 00:15:17.633 And I can kind of go into this and inspect the different commands. 00:15:17.633 --> 00:15:19.400 But I want to see what's actually running. 00:15:19.400 --> 00:15:21.266 If I expand this right toggle. 00:15:21.266 --> 00:15:23.666 Now you'll notice that it's giving me a preview tab. 00:15:23.666 --> 00:15:26.666 We don't see anything right now because we're just waiting for it to finish the files. 00:15:26.666 --> 00:15:32.400 But we will be able to see all of the different files, code changes and all this stuff going on here in one second. 00:15:32.400 --> 00:15:39.266 And then if I go here to this kind of little, I don't know, to do list icon, you can see that we have a bunch of options. 00:15:39.266 --> 00:15:40.866 So I can change where I want it to work. 00:15:40.866 --> 00:15:44.100 I can change the branch I can commit or push directly to GitHub. 00:15:44.133 --> 00:15:47.433 Now it's not giving us any results because it's not available online right now. 00:15:47.433 --> 00:15:49.033 It's just locally on our computer. 00:15:49.033 --> 00:15:49.833 But you get the idea. 00:15:49.833 --> 00:15:52.033 And then we can view the changes which is making right now. 00:15:52.033 --> 00:15:53.633 So we're just waiting for those to finish. 00:15:53.633 --> 00:15:56.700 So there's a lot that will start happening when you actually write code. 00:15:56.700 --> 00:15:58.729 And then I can also toggle open the terminal. 00:15:58.729 --> 00:15:59.000 Right. 00:15:59.000 --> 00:16:01.233 So I can run commands or see what's happening there. 00:16:01.233 --> 00:16:02.633 Let's go back into this view. 00:16:02.633 --> 00:16:06.200 And then I can open this in any of the tools that are shown here. 00:16:06.200 --> 00:16:11.233 So if I wanted to open this in cursor and view all of the code in IDE, I can press that button and do so. 00:16:11.233 --> 00:16:12.200 So let's wait a second for it. 00:16:12.200 --> 00:16:19.600 To finish writing this code, you can see that it's starting to show me some of the files that we have inside of this folder, and then we'll review it and see what we get okay. 00:16:19.633 --> 00:16:21.533 So just finished the first pass here. 00:16:21.533 --> 00:16:24.800 It says that it built the multiplayer chess MVP and started locally. 00:16:24.800 --> 00:16:29.300 And if I press on any of the links here, you'll notice that they'll actually open directly in Codex. 00:16:29.300 --> 00:16:31.266 So you can see that it's opened up right here. 00:16:31.266 --> 00:16:32.400 We kind of have this view. 00:16:32.400 --> 00:16:35.066 I can change the view, make it large or small or whatever. 00:16:35.066 --> 00:16:38.133 So let's give a username maybe like Tim okay. 00:16:38.200 --> 00:16:39.400 And join the game. 00:16:39.400 --> 00:16:41.733 And then let's try to find a game okay. 00:16:41.733 --> 00:16:43.800 And then I'm just going to open up another browser here. 00:16:43.800 --> 00:16:46.900 So you can see I can press this plus button go browser. 00:16:46.900 --> 00:16:48.833 We can actually manually type. 00:16:48.833 --> 00:16:51.200 So localhost 3000 okay. 00:16:51.200 --> 00:16:55.533 And let's see maybe we can change this as I don't know Joe or something. 00:16:55.866 --> 00:16:56.251 Okay. 00:16:56.251 --> 00:16:58.100 Join in and find a game. 00:16:58.100 --> 00:17:01.033 And you can see that we find a game and then we can start playing. 00:17:01.033 --> 00:17:04.733 So I don't know let me try to move here and see if it moves on this side. 00:17:04.733 --> 00:17:05.800 And it looks like it's working. 00:17:05.800 --> 00:17:12.100 So let's make a move like that I'm not going to play the full thing out, but you guys get the idea that it is indeed working. 00:17:12.100 --> 00:17:13.579 We have a track of all the moves. 00:17:13.579 --> 00:17:14.700 We have some leaderboard. 00:17:14.700 --> 00:17:24.233 And then maybe if I resign, you can see now the ELO has updated and I want so says white wins by resignation I mean pretty cool that that worked that fast. 00:17:24.266 --> 00:17:27.266 Now within this browser view there's a few buttons you should be aware of. 00:17:27.266 --> 00:17:31.133 So if you have a look at this right hand side, you can see that you can actually take a screenshot. 00:17:31.133 --> 00:17:33.000 If you do that, it will save it to the clipboard. 00:17:33.000 --> 00:17:41.066 And then you can copy that screenshot or paste it sorry, into the chat in case you want to capture what's going on inside of this window rather than doing it manually. 00:17:41.066 --> 00:17:44.900 And of course, ChatGPT and GPT here can do image generation. 00:17:44.900 --> 00:17:46.000 It can view images. 00:17:46.000 --> 00:17:47.933 So that's I mean it should be straightforward. 00:17:47.933 --> 00:17:49.066 You also can annotate. 00:17:49.066 --> 00:17:53.200 So if you annotate this will allow you to select different HTML elements. 00:17:53.200 --> 00:17:57.866 So for example maybe I'm going to select this and I can say something like I don't really like this title. 00:17:57.866 --> 00:18:01.366 I think we can make it look a lot better and put a chess logo okay. 00:18:01.433 --> 00:18:06.533 And then we can go here and we can actually just update any of the values directly on screen. 00:18:06.533 --> 00:18:10.433 I'm not going to do that because I would prefer just to prompt it, but I'm just going to run that. 00:18:10.466 --> 00:18:14.633 You can see we now have an annotation in chat and I can start adding other annotations. 00:18:14.633 --> 00:18:22.600 So maybe I'm going to say can we change the color of the board or have like a white or dark mode, or maybe change the square colors? 00:18:22.800 --> 00:18:25.033 I'm just giving random prompts going to show you this works. 00:18:25.033 --> 00:18:28.333 And you can see we have annotations and I can say like go or something. 00:18:28.333 --> 00:18:35.066 And now it's going to have the annotations that we made in the browser, and it's going to make those changes which are a lot more targeted. 00:18:35.100 --> 00:18:35.295 Okay. 00:18:35.295 --> 00:18:37.833 So I just refresh because I want to see what this was doing live. 00:18:37.833 --> 00:18:42.200 And you can see if I go here now and I refresh, we've kind of changed what the board looks like. 00:18:42.233 --> 00:18:43.498 Obviously we've disconnected. 00:18:43.498 --> 00:18:44.633 Now we're waiting to join. 00:18:44.633 --> 00:18:49.100 We can see we have the kind of chess icon and it's essentially followed the annotations we asked for. 00:18:49.133 --> 00:18:49.333 Okay. 00:18:49.333 --> 00:18:54.700 So hopefully that gave you a bit of information on how the general kind of coding works inside of Codex. 00:18:54.733 --> 00:18:56.033 It's very good for me. 00:18:56.033 --> 00:18:59.100 I really like this user interface, and I like using this application. 00:18:59.100 --> 00:19:03.866 And I mean, you can see that it gives us pretty good results, even though I didn't do anything crazy. 00:19:03.866 --> 00:19:06.066 So now let's move to a few more advanced features. 00:19:06.066 --> 00:19:08.633 Let's start by having a look at some basic commands. 00:19:08.633 --> 00:19:11.633 So commands are just anything that start with a slash. 00:19:11.633 --> 00:19:16.600 And there's a ton of built in commands inside of cloud code or not cloud code inside of Codex. 00:19:16.600 --> 00:19:20.433 I'm not going to go over all of them, but I'll show you a few that you should be aware of. 00:19:20.466 --> 00:19:24.600 So first, if we do slash, we're going to want to look at status. 00:19:24.633 --> 00:19:26.866 Now status will just show you your usage limit. 00:19:26.866 --> 00:19:29.700 So you can see that for a five hour limit I'm at 98%. 00:19:29.700 --> 00:19:32.433 And for my seven day limit I'm at 99%. 00:19:32.433 --> 00:19:34.400 It also gives me my context limit. 00:19:34.400 --> 00:19:39.466 Now the context can be viewed using this little kind of circular icon down here. 00:19:39.466 --> 00:19:45.866 It won't give you a detailed breakdown, but you'll be able to see how much you've used, how much is left, and how many tokens are there. 00:19:45.900 --> 00:19:59.933 Now, depending on the models you're using, the context size can change, but this is something that's useful to be aware of because if the context gets too large, which means you have too many, you know, too much conversation, history, tool calls, etc., you will need to compact that. 00:20:00.100 --> 00:20:02.266 Now there's actually a command that can do this for you. 00:20:02.266 --> 00:20:04.066 It's called slash compact. 00:20:04.066 --> 00:20:09.800 Now what slash compact will do is it will take everything that you have in your current conversation history. 00:20:09.800 --> 00:20:21.133 So all of the tool calls, all of the code, anything that it's understood in this whole conversation that we've had, and it will generate a summary of that and then add that to kind of a new, fresh conversation that you'll start. 00:20:21.133 --> 00:20:27.200 So you'll notice that after I did that, we now if we look at the what is it context use here, we've only used for percent. 00:20:27.200 --> 00:20:29.100 So it's taken 22% there. 00:20:29.100 --> 00:20:31.633 It's condensed it down given us a summary. 00:20:31.633 --> 00:20:33.000 And now we can continue. 00:20:33.000 --> 00:20:37.933 Now it's not a great idea to compact super early because you want to use up the context window. 00:20:37.933 --> 00:20:46.133 But as soon as you start getting to 70%, 80%, 90% context, you typically want to compacted because you're going to get better results. 00:20:46.133 --> 00:20:50.066 Because as the model fills up with context, it performs worse. 00:20:50.100 --> 00:20:51.233 This is pretty well known. 00:20:51.233 --> 00:20:52.900 I'm not going to go into all of the details. 00:20:52.900 --> 00:20:54.700 Just be aware that command exists. 00:20:54.700 --> 00:21:00.300 You can use it in Codex will automatically compact for you if you're going to go past your context. 00:21:00.300 --> 00:21:05.300 So you may want to do it at a time that you decide, rather than waiting for it to do it automatically. 00:21:05.333 --> 00:21:08.933 Now, another thing that we can do, which is sometimes useful, is we can fork this. 00:21:08.933 --> 00:21:16.533 Now you can see that if we type slash fork, it will allow us to fork this chat into a local or new work tree, which we're going to look at effectively. 00:21:16.533 --> 00:21:26.033 What this will do is take everything that we've done and just create a complete copy of it, so we can work in multiple agents at the same time without them having any conflict. 00:21:26.033 --> 00:21:33.066 So they both will kind of work in their own copy of the code base, and then they can go and kind of joy in everything together. 00:21:33.100 --> 00:21:34.700 Fix any of the merge conflicts. 00:21:34.700 --> 00:21:39.266 When we get to the final version again, we'll look at fork in a minute, but that is a command to be aware of. 00:21:39.266 --> 00:21:40.803 You have the fast mode feedback. 00:21:40.803 --> 00:21:42.100 We're not going to do that. 00:21:42.100 --> 00:21:45.833 A NIT goal and some other kind of modes that we'll look at here in a second. 00:21:45.866 --> 00:21:46.933 Few last things to be aware of. 00:21:46.933 --> 00:21:48.100 You can also pin chats. 00:21:48.100 --> 00:21:50.433 So if we want this chat to be available we can pin it. 00:21:50.433 --> 00:21:53.200 And then we can create new chats inside of the same project. 00:21:53.200 --> 00:21:54.800 So you can see it's in chess game here. 00:21:54.800 --> 00:22:00.033 And we can decide how we want to work and just have another agent either running at the same time or in a new chat. 00:22:00.033 --> 00:22:05.054 If we want to ask for something different and kind of forget the previous conversation history we had here. 00:22:05.054 --> 00:22:07.333 Anyways, let's go to a new chat. 00:22:07.333 --> 00:22:12.733 Now we're inside of chess game, and let's use a new mode that we haven't seen yet, which is plan. 00:22:12.733 --> 00:22:16.133 So if we use slash plan, we can enable plan mode. 00:22:16.133 --> 00:22:17.733 You'll see that it's here and now. 00:22:17.733 --> 00:22:22.200 With plan mode, what we can do is we can ask this something a little bit more detailed. 00:22:22.200 --> 00:22:23.800 We can describe what we want. 00:22:23.800 --> 00:22:30.233 And Codex will prompt us with different questions and kind of clarifying details before it goes and executes the plan. 00:22:30.266 --> 00:22:34.400 Pretty straightforward, but typically you want to make a plan before you do something too complex. 00:22:34.400 --> 00:22:39.200 So really for our chess game, we should have started in plan mode, built the plan, and then execute it. 00:22:39.200 --> 00:22:42.100 I was just saving it for later because it's a little bit more complex. 00:22:42.100 --> 00:22:44.933 So now maybe I want to expand this chess game. 00:22:44.933 --> 00:22:45.936 I want to have puzzles. 00:22:45.936 --> 00:22:47.200 I want to have a leaderboard. 00:22:47.200 --> 00:22:50.400 I want to have maybe a big UI, I want to have whatever accounts. 00:22:50.400 --> 00:22:52.400 So let's start generating a plan for that. 00:22:52.400 --> 00:22:54.700 I want to expand our chess game. 00:22:54.700 --> 00:23:03.900 I want to have a better landing page so that a user can see their stats, and they have the ability to either play a game or play a puzzle or go to like a practice board. 00:23:03.900 --> 00:23:09.833 I want to generate a few different game modes, and I want to really polish this up and make it kind of like a Chess.com clone. 00:23:09.866 --> 00:23:11.733 Let's start with just the MVP features. 00:23:11.733 --> 00:23:13.133 Can you generate a plan for this? 00:23:13.133 --> 00:23:18.000 Ask me any questions you need to okay, so let's go here and press enter. 00:23:18.000 --> 00:23:21.066 And because it's in plan mode it's going to map everything out. 00:23:21.066 --> 00:23:26.100 And it should start asking us some questions and prompting us so that it can generate that for us. 00:23:26.133 --> 00:23:26.400 Okay. 00:23:26.400 --> 00:23:29.433 So we can see that it's now prompting us with a few questions in the bottom here. 00:23:29.433 --> 00:23:34.133 So it says for the first MVP pass, which mode set should the landing page launch? 00:23:34.233 --> 00:23:40.066 We can have add bot game, add time modes or core three ship the landing page, live game, daily star puzzles. 00:23:40.066 --> 00:23:41.033 Let's go with that. 00:23:41.033 --> 00:23:43.400 How should the user stats work for an MVP? 00:23:43.400 --> 00:23:44.400 Let's just go. 00:23:44.400 --> 00:23:45.196 Username. 00:23:45.196 --> 00:23:46.433 Profiles okay. 00:23:46.433 --> 00:23:47.360 Username. 00:23:47.360 --> 00:23:47.978 Login. 00:23:47.978 --> 00:23:49.318 Expand stats. 00:23:49.318 --> 00:23:49.833 Okay. 00:23:49.866 --> 00:23:52.466 How deep should the puzzle mode be an MVP? 00:23:52.466 --> 00:23:53.633 Let's just do. 00:23:54.633 --> 00:23:54.900 Yes. 00:23:54.900 --> 00:23:58.500 Small bundled puzzled library that looks good and that we continue. 00:23:58.533 --> 00:24:03.333 Now while it's doing this, also mention that if you open up the sidebar here, you'll see a few more options. 00:24:03.333 --> 00:24:07.400 Because we're in this kind of coding environment, we can now view all of the files. 00:24:07.400 --> 00:24:09.433 If we want to look at this, we see we have the database. 00:24:09.433 --> 00:24:11.100 We can open up the server right. 00:24:11.100 --> 00:24:15.900 And you can modify the code, or you can add comments directly inside of here or tag different things. 00:24:15.900 --> 00:24:18.300 And now you'll see that it's generating the plan. 00:24:18.300 --> 00:24:20.466 I believe the plan will be stored in this repo. 00:24:20.466 --> 00:24:23.666 I might just need to refresh, but we should be able to view it. 00:24:23.666 --> 00:24:29.466 So if I want to look at the plan here, you can see we can open it up and it gives us everything that needs to be done. 00:24:29.500 --> 00:24:29.900 Okay. 00:24:29.900 --> 00:24:33.600 So I could just implement this plan right and just start running with that. 00:24:33.600 --> 00:24:45.100 But what I want to show you now is another mode that's super useful, that is going to get things done a lot more efficiently for us without us having to keep approving things or prompting the model multiple times. 00:24:45.100 --> 00:24:47.033 And that is called goal. 00:24:47.033 --> 00:24:50.700 So there is this slash command called slash goal. 00:24:50.733 --> 00:24:54.600 Now if we use this let me just actually type it out. 00:24:54.633 --> 00:24:59.733 What will happen is that codex will run until a goal is achieved. 00:24:59.733 --> 00:25:04.733 Now this is kind of that agent loops that you may have heard about recently that everyone's talking about. 00:25:04.800 --> 00:25:06.033 They have that built in now. 00:25:06.033 --> 00:25:09.200 So what we can do is we can say, hey, here's the goal. 00:25:09.200 --> 00:25:14.433 And we just set a high level objective, and Codex will keep going until the goal is achieved. 00:25:14.433 --> 00:25:18.066 So it will plan, it will execute and then it will review if it's achieved the goal. 00:25:18.066 --> 00:25:20.400 And if it hasn't, it will just keep running. 00:25:20.400 --> 00:25:24.000 So it's not just going to do one pass or implement one set of features. 00:25:24.000 --> 00:25:26.300 It will go until the goal is achieved. 00:25:26.300 --> 00:25:32.000 Now, in order to use this effectively, you need to set a good goal and the conditions for the goal to be achieved. 00:25:32.033 --> 00:25:38.300 Now, in our case, we already have the plan so we can effectively just say keep running until the entire plan is implemented. 00:25:38.300 --> 00:25:40.333 It will then run check if the plan is done. 00:25:40.333 --> 00:25:41.900 If it's not, it will keep going. 00:25:41.900 --> 00:25:43.400 If it is, it will finish. 00:25:43.400 --> 00:25:48.233 So this will allow it to run for a long period of time, which also will use a lot of usage. 00:25:48.233 --> 00:25:49.733 So keep that in mind. 00:25:49.733 --> 00:25:55.666 So for the goal I'm going to say okay, keep running and implement the entire plan until the plan is fully finished. 00:25:55.666 --> 00:26:00.333 Everything is tested, everything is working and we are confident to deploy this. 00:26:00.633 --> 00:26:03.666 Again, not the best prompt in the world, but I'm just showing you the usage here. 00:26:03.666 --> 00:26:07.000 And now that the plan is enabled, we have goal set. 00:26:07.066 --> 00:26:11.633 I can press enter and you can see that it's going to pursue this goal and start running. 00:26:11.633 --> 00:26:13.466 And we can view this is the goal. 00:26:13.466 --> 00:26:15.466 And it's going through all of the different steps. 00:26:15.466 --> 00:26:19.633 And it will just be this infinite loop which can take a very long time to run. 00:26:19.666 --> 00:26:19.933 All right. 00:26:19.933 --> 00:26:22.900 So the goal has just finished it built this application for us. 00:26:22.900 --> 00:26:26.133 I don't know if it's fully working, but you guys get the idea and it's done. 00:26:26.200 --> 00:26:29.900 So now let's have a look at some more features and start going through it okay. 00:26:29.933 --> 00:26:31.000 So first things first. 00:26:31.000 --> 00:26:34.600 If you look at any of these chats you have the ability to right click them. 00:26:34.600 --> 00:26:36.833 You can pin them rename them. 00:26:36.833 --> 00:26:40.733 You can also fork them into a local version or a new work tray. 00:26:40.733 --> 00:26:48.233 Now I want to really briefly discuss what a work tree is, because it's a little bit complicated, and we'll save the full usage for a part two. 00:26:48.266 --> 00:26:51.100 So let me know if you guys want to see that in the comments down below. 00:26:51.100 --> 00:26:53.866 Now, if I try to open a new project here, right. 00:26:53.866 --> 00:26:54.700 So I've gone sorry. 00:26:54.700 --> 00:26:55.266 New chat. 00:26:55.266 --> 00:26:56.501 Okay, so I want new chat. 00:26:56.501 --> 00:26:58.033 And then I selected Chess Game. 00:26:58.033 --> 00:27:02.066 And then what I did is rather than selecting work locally, I selected new work tree. 00:27:02.066 --> 00:27:05.266 I have the ability to create a local environment. 00:27:05.300 --> 00:27:15.466 Now the reason this is important is that if you want to run parallel agents at the same time, they should be working in their own copy of the repository or the project that you have. 00:27:15.533 --> 00:27:22.633 If they work on the same files, there can be conflicts because they're touching the same information at the same time, and that's not good. 00:27:22.666 --> 00:27:25.466 So the solution to this is a work tree. 00:27:25.466 --> 00:27:27.466 This is provided by git. 00:27:27.466 --> 00:27:31.000 Again it's a little bit complicated to setup and a bit confusing to use. 00:27:31.000 --> 00:27:32.933 So I'm not going to go through all of the details. 00:27:32.933 --> 00:27:39.933 But if you do want to run parallel agents at the same time, you have multiple tasks going, this is what you would use. 00:27:39.933 --> 00:27:47.800 You have to configure the environment first, which you can ask Codex to help you do, and then you can change the branches and stuff in order to work on the different features. 00:27:47.800 --> 00:27:54.633 And now you'll have different agents because you can run multiple at the same time, working in these kind of copies of the same repo. 00:27:54.633 --> 00:27:58.733 Again, this is a more advanced developer feature, so I'm not going to dive into it too much. 00:27:58.800 --> 00:28:01.133 Now, another feature that's somewhat related to this. 00:28:01.133 --> 00:28:02.733 Let's go back to local copy. 00:28:02.733 --> 00:28:05.700 Here is this tool called Slash Review. 00:28:05.700 --> 00:28:13.733 Now this is a code review that can automatically compare any changes that have been made in the current session against what's in GitHub. 00:28:13.800 --> 00:28:14.266 Okay. 00:28:14.266 --> 00:28:22.000 So if I go to maybe this right now and I go slash review, you can see that I can review this against a base branch. 00:28:22.000 --> 00:28:26.400 So a branch in git if you're familiar with that or review any uncommitted changes. 00:28:26.400 --> 00:28:39.300 So if I go slash review right and then uncommitted changes it's going to start looking at all of the changes that it made here and automatically review them to make sure that they're good before we push them to get or before we commit them. 00:28:39.300 --> 00:28:47.600 This is a pretty useful feature that Codex has, and this is something you should always do after you've done a large amount of changes before you push them to remote repository. 00:28:47.600 --> 00:28:49.066 And if you don't know what that means, don't worry. 00:28:49.066 --> 00:28:55.400 But if you're a developer, you'll understand the value of having a built in shortcut that will do all of those passes and checks for you. 00:28:55.433 --> 00:28:58.833 Okay, so you can see that it's done the review and it's given us some comments now. 00:28:58.833 --> 00:29:02.233 And it said, hey, these are errors that I found after doing the code review. 00:29:02.266 --> 00:29:02.545 Right. 00:29:02.545 --> 00:29:04.266 So let me go ahead and fix them okay. 00:29:04.266 --> 00:29:07.866 So let's move to the next feature which is memory and context. 00:29:07.900 --> 00:29:13.900 Now this is less maybe, I don't know demo wise and more me explaining how this works because I want you to understand this. 00:29:13.900 --> 00:29:16.833 So if I make a new chat right here okay. 00:29:16.833 --> 00:29:20.466 And we go into this and I'm working locally, I want you to see something. 00:29:20.600 --> 00:29:25.100 What did I do in my last session when I was working on the chess game? 00:29:25.200 --> 00:29:36.433 Now, the reason why I'm going to run this prompt and show you the result, is that you need to understand that by default, Codex doesn't remember things that you worked on in the past. 00:29:36.433 --> 00:29:47.866 Anytime you create a new chat, what it's doing is reviewing anything that you have in your current repo, kind of trying to load in information and find any context that's relevant and then give you an answer. 00:29:47.866 --> 00:29:50.933 But by default it doesn't remember everything that you did. 00:29:50.933 --> 00:29:53.500 So it won't have the full conversation history. 00:29:53.500 --> 00:29:59.066 It won't know maybe preferences that you told it, and it can forget things because it doesn't remember by default. 00:29:59.100 --> 00:30:07.433 The only reason this actually just gave me a response is because it looked inside of my project here that I'm inside of and was able to find that information. 00:30:07.433 --> 00:30:13.233 But if I go to a new chat and I say and I remove the project, what did I work on for my chess game? 00:30:13.400 --> 00:30:17.033 And I just ask it something really vague like that, it shouldn't know. 00:30:17.200 --> 00:30:20.800 At least I don't think it will know because it's not going to have any of that context. 00:30:20.833 --> 00:30:27.800 The reason why I'm mentioning this is that you need to understand that anytime you make a new session, you're effectively starting from scratch. 00:30:27.800 --> 00:30:31.633 And anything that you want this to know, it has to already exist as a file. 00:30:31.633 --> 00:30:34.700 It has to be saved persistently so Codex can read it in. 00:30:34.700 --> 00:30:39.333 And you can see here that it's not able to really find the information very well for me here. 00:30:39.333 --> 00:30:46.233 And it has to actually go and look through the different conversation history and threads to find this information so it can find it. 00:30:46.233 --> 00:30:51.433 But the only reason it can do that is because it's searching through the threads and it's very slow. 00:30:51.433 --> 00:30:53.900 And again, it's not going to remember everything by default. 00:30:53.900 --> 00:31:01.233 The reason why I'm mentioning this is that you can fix this problem by creating something called an agent dot file. 00:31:01.233 --> 00:31:15.800 Now this is something that's common in all of your code base tools, CLI based tools, whatever AI agents where you can make effectively a memory file that will always be loaded into the prompt or into the model before you start working with it. 00:31:15.800 --> 00:31:25.133 Now this is a really good file to create, especially when you're working on larger projects with multiple people, because you can store preferences, different tools or stacks that you want to use. 00:31:25.200 --> 00:31:31.400 I wouldn't say credentials, but you can store just important info that you don't want to have to keep telling the model over and over again. 00:31:31.433 --> 00:31:33.466 So for example, I can tell this. 00:31:33.466 --> 00:31:43.266 I would like you to create an agent file with all of the conventions for this project, specifically the tech stack that we're using, how to run it, and what we've set up so far. 00:31:43.900 --> 00:31:44.400 Okay. 00:31:44.400 --> 00:31:48.300 And what this will do now is create a new file for us called agents. 00:31:48.833 --> 00:31:50.000 You'll see it in a second. 00:31:50.000 --> 00:31:52.433 It's automatically making it starts with all capitals. 00:31:52.433 --> 00:31:55.666 And it's going to fill this file with important info then. 00:31:55.666 --> 00:32:04.066 Now we're never going to forget or Codex will never forget because this is by default automatically load it into Codex anytime we make a new conversation. 00:32:04.066 --> 00:32:06.833 So let's give this a second to make the file and see what it looks like. 00:32:06.833 --> 00:32:13.400 So let's open this up and you can see that it gives us project conventions, direction, tech stack, how to run it, etc.. 00:32:13.433 --> 00:32:18.400 So now if we make a new conversation, I go, what are the project conventions? 00:32:18.400 --> 00:32:22.033 It's not going to have to search through a bunch of files to find this. 00:32:22.066 --> 00:32:28.033 It can just get it directly from its kind of system info now, because it will have been loaded in and MD. 00:32:28.033 --> 00:32:30.433 So you can see it just immediately gives us the result. 00:32:30.433 --> 00:32:35.233 It doesn't need to read anything because it was already loaded in when we started the conversation. 00:32:35.233 --> 00:32:42.333 If we look at the context, you can see the context is slightly higher usage than normal because it's started by loading that file. 00:32:42.500 --> 00:32:43.800 I hope that that makes sense to you. 00:32:43.800 --> 00:32:56.100 I know that's not the best explanation possible, but anything that you want to be kind of long term, persistent info that's going to be used all of the time, you want to put it in this agents MD file and tell Codex to create that for you. 00:32:56.100 --> 00:33:02.466 And you can continually update this to improve the performance of the model you use in a particular project. 00:33:02.500 --> 00:33:06.900 Okay, so that is kind of the agents, the in memory info that you need to know. 00:33:06.900 --> 00:33:09.200 And the last thing we'll look at is scheduled tasks. 00:33:09.200 --> 00:33:19.933 Now I'm not going to actually create these, but I'm just going to mention that they exist just like cloud code or other tools that you may have used, you can create scheduled tasks that run automatically for you, assuming your computer is on. 00:33:19.933 --> 00:33:26.000 So you can make a daily brief where every morning it opens your computer, searches the news and gives you some info. 00:33:26.000 --> 00:33:29.200 You can do a weekly review where it tells you all the things you worked on. 00:33:29.200 --> 00:33:32.233 You can do project monitor where if something changes, we do this. 00:33:32.233 --> 00:33:39.466 So if I do create via chat, for example, I can make it to set up a scheduled task for me automatically, or I can go to templates and I can pick one. 00:33:39.466 --> 00:33:41.933 So maybe like this, this is what I want to do. 00:33:41.933 --> 00:33:45.466 I want to run it in this chat or in a work tree. 00:33:45.833 --> 00:33:47.266 I want to in this project. 00:33:47.266 --> 00:33:49.300 I want it to repeat at this time. 00:33:49.300 --> 00:33:50.800 Then this is the model that I want to use. 00:33:50.800 --> 00:33:51.042 Okay. 00:33:51.042 --> 00:33:52.400 So again you can make these. 00:33:52.400 --> 00:33:59.133 You can have them set to run and you can set this up to kind of automatically do things for you, which is useful if you want some automations. 00:33:59.133 --> 00:34:00.428 But for me I don't really need any. 00:34:00.428 --> 00:34:01.833 So I don't have those setup as of now. 00:34:01.833 --> 00:34:10.733 And then of course, you can search through all of your chats and a bunch of other stuff, and we can go crazy and we can go to add MCP servers. 00:34:10.733 --> 00:34:12.333 We can control the browser use. 00:34:12.333 --> 00:34:16.633 We can do computer use, hooks, connections, git environments, work trees. 00:34:16.633 --> 00:34:19.333 There is a lot more to go over, but I'm going to save that for a part two. 00:34:19.333 --> 00:34:32.700 If you guys let me know in the comments that you want to see an advanced version of this that is going to wrap up this video, that was a pretty comprehensive overview of Codex, a lot of the features, how to use it, some good demos, setting up a lot of the important plugins. 00:34:32.700 --> 00:34:35.900 At this point, you know, probably 90% of Codex. 00:34:35.966 --> 00:34:39.633 If you want the extra 10%, let me know and I will happily make an advanced version. 00:34:39.633 --> 00:34:43.666 For those of you that are devs and are kind of past some of the beginner stuff that I showed here. 00:34:43.666 --> 00:34:44.900 Anyway, I hope you enjoyed. 00:34:44.900 --> 00:34:48.633 If you did leave a like subscribe and I will see you in the next one.
