WEBVTT Kind: captions Language: en-CA 00:00:00.266 --> 00:00:02.266 This video will teach you Codex. 00:00:02.266 --> 00:00:06.033 I'll go through all of the important features, show you how to set it up and install it, 00:00:06.033 --> 00:00:07.533 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 --> 00:00:18.666 I'm going to show you how to set it up for coding model selection, all of the different commands 00:00:18.666 --> 00:00:22.966 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 --> 00:00:54.833 It's actually much more involved than Claude code I would say it has a lot more features, 00:00:54.833 --> 00:00:57.266 and a lot of people don't know about what you can do with it. 00:00:57.266 --> 00:00:59.700 Now, the basics is that you can use it to write code 00:00:59.700 --> 00:01:03.700 because it will give you access to their top models like GPT 5.5. 00:01:03.733 --> 00:01:07.433 However, you can also use it to control your computer, to automate 00:01:07.466 --> 00:01:10.500 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 --> 00:01:30.033 And OpenAI has been very confusing with the naming of Codex 00:01:30.033 --> 00:01:33.600 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 --> 00:02:11.066 Then you would compare it to something like Claude Code, so I wouldn't be too concerned 00:02:11.066 --> 00:02:11.933 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 --> 00:02:25.400 So first up, if you don't want to be downloaded and installed Codex, I'll leave a link to it 00:02:25.400 --> 00:02:29.500 in the description sign in with your ChatGPT account, then you're good to go 00:02:29.533 --> 00:02:33.066 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 --> 00:02:38.300 You can install this in the popular editors like cursor, Visual Studio 00:02:38.300 --> 00:02:43.100 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 --> 00:02:50.833 Now this is a command line interface more familiar to something like cloud Code, where you're 00:02:50.833 --> 00:02:54.000 not in kind of a nice graphical user interface, which you'll see in a minute. 00:02:54.000 --> 00:02:57.533 But the advantage here is that you can run this on something like Linux or a server, 00:02:57.533 --> 00:03:00.866 and you can have this as a remote machine that's running 24 over seven. 00:03:00.900 --> 00:03:02.533 Same thing. 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 --> 00:03:09.233 It's better if you can use the desktop version, but if you want to do it 00:03:09.233 --> 00:03:12.266 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 --> 00:03:17.433 Again, what we want to do is download the desktop application, 00:03:17.433 --> 00:03:19.066 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 --> 00:03:24.100 So just open up the desktop application, which is where we're going to be working 00:03:24.100 --> 00:03:27.833 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 --> 00:03:40.433 There's a few things you want to pay attention to, like the model selector which we'll look at in 00:03:40.433 --> 00:03:44.233 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 --> 00:03:54.733 So if you do forward slash 00:03:54.733 --> 00:03:58.066 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 --> 00:04:25.466 You typically don't need to do this, but I'm just showing you 00:04:25.466 --> 00:04:27.533 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 --> 00:04:47.133 So it's going to be a little bit less technical, but for most of us, we're going to want to stay here 00:04:47.133 --> 00:04:50.200 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 --> 00:05:00.733 And then last thing, if you go and look at usage and billing, you'll be able to see your usage, 00:05:00.733 --> 00:05:03.733 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 --> 00:05:16.633 Let's start running a few chats and setting up some plugins 00:05:16.633 --> 00:05:20.200 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 --> 00:05:28.400 Now this is one of the best learning platforms out there and actually a long term partner 00:05:28.400 --> 00:05:29.400 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 --> 00:05:53.800 You work through real challenges in Python SQL and go earn 00:05:54.400 --> 00:05:58.000 level up five bosses and progress through a full backend curriculum. 00:05:58.000 --> 00:06:01.266 Now it sounds a bit gimmicky, but I promise you it actually works because you're 00:06:01.266 --> 00:06:04.266 doing the same kind of problem solving that you do on the job. 00:06:04.266 --> 00:06:06.333 Now they also have an AI tutor called boots, 00:06:06.333 --> 00:06:10.200 which doesn't just dump answers on you, it asks follow up questions and helps 00:06:10.200 --> 00:06:14.833 you reason through problems when you get stuck, which is way closer to how you actually learn. 00:06:14.833 --> 00:06:19.066 Now, all of the content is free to read and watch, and if you want the interactive coding, 00:06:19.066 --> 00:06:22.933 the progress tracking, and the AI assistance, that's part of the paid plan. 00:06:23.000 --> 00:06:25.933 If you want to check it out, go to dev and use my code 00:06:25.933 --> 00:06:29.233 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 --> 00:06:43.433 Now from here if you go to model selector you're going to see that you have 00:06:43.433 --> 00:06:47.033 a reasoning level light medium high and extra high. 00:06:47.066 --> 00:06:50.633 Now of course you want to use the best reasoning whenever you possibly can, 00:06:50.666 --> 00:06:54.066 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 --> 00:07:02.833 Of course, the higher reasoning, the better responses and results that you're typically going to get, 00:07:02.833 --> 00:07:06.633 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 --> 00:07:13.433 If you're asking a quick question, 00:07:13.433 --> 00:07:17.333 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 --> 00:07:35.700 I would never use this one. GPT 5.4 mini. 00:07:35.733 --> 00:07:38.700 This can be used for small, fast, kind of efficient things 00:07:38.700 --> 00:07:42.400 where you're asking a question or you just want, you know, quick UI change or something. 00:07:42.400 --> 00:07:46.433 And then 5.3 Codec Spark is just an extremely fast model 00:07:46.433 --> 00:07:50.200 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 --> 00:08:06.933 I pretty much always leave that on, and then if you start running out of the usage, 00:08:06.933 --> 00:08:08.700 you can switch to some of these other models. 00:08:08.700 --> 00:08:10.500 You can change the speed back to default 00:08:10.500 --> 00:08:14.300 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 --> 00:08:16.500 And if you're doing something 00:08:16.500 --> 00:08:20.666 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 --> 00:08:43.266 And the fact that it can control your computer, control your browser, control spreadsheets, access 00:08:43.266 --> 00:08:47.066 Google Drive, and do this in a really interactive and intuitive way. 00:08:47.100 --> 00:08:50.500 Now, most of your tools like this like cloud code, they can do the same thing, 00:08:50.500 --> 00:08:54.866 but I find Codex performs a lot better and it's just way easier to understand. 00:08:54.866 --> 00:08:58.066 So what we're going to want to do here is go to plugins and start installing 00:08:58.066 --> 00:09:00.533 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 --> 00:09:36.300 It can search for something. 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 --> 00:09:55.233 You can store them in the clouds, 00:09:55.233 --> 00:09:58.333 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 --> 00:10:15.233 So it can automatically make what's called a repository, which is just storing 00:10:15.233 --> 00:10:18.933 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 --> 00:10:29.466 I'm not going to be teaching git in GitHub too much, but I do highly recommend 00:10:29.500 --> 00:10:31.300 that you set up that plugin and you can see 00:10:31.300 --> 00:10:35.533 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 --> 00:10:47.333 So if I go and I use this at symbol, you can see that I can actually reference 00:10:47.333 --> 00:10:50.666 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 --> 00:11:00.700 Open up notepad, close any of the existing windows that are there, 00:11:00.700 --> 00:11:05.266 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 --> 00:11:10.133 By the way, 00:11:10.133 --> 00:11:14.233 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 --> 00:11:19.133 I'll leave a link to it so you can check it out. 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 --> 00:11:39.066 So I can navigate into an application. I can close something. 00:11:39.066 --> 00:11:41.866 I don't need to have it kind of freely using the mouse, 00:11:41.866 --> 00:11:44.033 because it will actually use its own cursor. 00:11:44.033 --> 00:11:47.833 Okay, apologies, because it had a note there that I didn't want you guys to see, 00:11:47.833 --> 00:11:49.033 so I had to kind of rerun this. 00:11:49.033 --> 00:11:49.666 But you can see that 00:11:49.666 --> 00:11:54.600 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 --> 00:11:58.700 So now if I want to say something, can you continue this node and make it like double 00:11:58.700 --> 00:12:00.600 or triple the length? 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 --> 00:12:07.666 And it's able to take over 00:12:07.666 --> 00:12:12.433 and do anything that we want, which can be super useful, especially for automating, 00:12:12.466 --> 00:12:17.100 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 --> 00:12:20.433 So let's see how it works. 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 --> 00:12:36.633 I'm going to say computer, open up Spotify, find Drake's 00:12:36.633 --> 00:12:40.133 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 --> 00:12:54.300 So we can see it opened this, it actually started playing the song, I just paused, 00:12:54.300 --> 00:12:56.833 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 --> 00:13:11.266 So if we're done with the current chat 00:13:11.266 --> 00:13:14.533 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 --> 00:14:07.600 We can work locally, which just means we're working on our own computer, 00:14:07.600 --> 00:14:09.033 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 --> 00:14:16.033 Now we're going to look at work trees later, but essentially this is a clone of this kind of project 00:14:16.033 --> 00:14:19.500 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 --> 00:14:46.400 I want to have a back end which is using WebSockets and kind of keeping 00:14:46.433 --> 00:14:50.200 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 --> 00:15:14.733 It's making multiple files. 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 --> 00:15:31.000 But we will be able to see all of the different files, code changes and all this stuff 00:15:31.000 --> 00:15:32.400 going on here in one second. 00:15:32.400 --> 00:15:35.666 And then if I go here to this kind of little, 00:15:35.700 --> 00:15:39.266 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 --> 00:15:59.000 And then I can also toggle open the terminal. 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 --> 00:16:15.300 To finish writing this code, you can see that it's starting to show me some of the files 00:16:15.300 --> 00:16:19.600 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 --> 00:16:58.100 Okay. 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 --> 00:17:08.033 So let's make a move like that 00:17:08.033 --> 00:17:12.100 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 --> 00:17:14.700 We have a track of all the moves. We have some leaderboard. 00:17:14.700 --> 00:17:19.933 And then maybe if I resign, you can see now the ELO has updated and I want so says 00:17:20.000 --> 00:17:24.233 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 --> 00:17:37.233 And then you can copy that screenshot or paste it sorry, into the chat 00:17:37.233 --> 00:17:41.066 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 --> 00:17:56.233 So for example maybe I'm going to select this and I can say something like 00:17:56.266 --> 00:17:57.866 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 --> 00:18:18.300 So maybe I'm going to say can we change the color of the board 00:18:18.300 --> 00:18:22.600 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 --> 00:18:32.033 And now it's going to have the annotations that we made in the browser, 00:18:32.033 --> 00:18:35.066 and it's going to make those changes which are a lot more targeted. 00:18:35.100 --> 00:18:37.833 Okay. 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 --> 00:18:44.633 Obviously we've disconnected. 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 --> 00:19:42.533 It won't give you a detailed breakdown, but you'll be able to see 00:19:42.533 --> 00:19:45.866 how much you've used, how much is left, and how many tokens are there. 00:19:45.900 --> 00:19:49.700 Now, depending on the models you're using, the context size can change, but this is something 00:19:49.700 --> 00:19:54.500 that's useful to be aware of because if the context gets too large, which means you have too many, 00:19:54.500 --> 00:19:59.933 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 --> 00:20:06.000 Now what slash compact will do 00:20:06.000 --> 00:20:09.800 is it will take everything that you have in your current conversation history. 00:20:09.800 --> 00:20:13.233 So all of the tool calls, all of the code, anything that it's understood 00:20:13.233 --> 00:20:17.266 in this whole conversation that we've had, and it will generate a summary of that 00:20:17.266 --> 00:20:21.133 and then add that to kind of a new, fresh conversation that you'll start. 00:20:21.133 --> 00:20:24.300 So you'll notice that after I did that, we now if we look at the 00:20:24.333 --> 00:20:27.200 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 --> 00:20:42.466 But as soon as you start getting to 70%, 80%, 90% context, 00:20:42.500 --> 00:20:46.133 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 --> 00:21:12.233 Now you can see that if we type slash fork, it will allow us to fork this chat 00:21:12.233 --> 00:21:16.533 into a local or new work tree, which we're going to look at effectively. 00:21:16.533 --> 00:21:20.666 What this will do is take everything that we've done and just create a complete copy of it, 00:21:20.666 --> 00:21:26.033 so we can work in multiple agents at the same time without them having any conflict. 00:21:26.033 --> 00:21:29.233 So they both will kind of work in their own copy of the code base, 00:21:29.233 --> 00:21:33.066 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 --> 00:21:36.466 When we get to the final version again, 00:21:36.466 --> 00:21:39.266 we'll look at fork in a minute, but that is a command to be aware of. 00:21:39.266 --> 00:21:42.100 You have the fast mode feedback. 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 --> 00:21:57.933 And we can decide how we want to work and just have another agent either 00:21:57.933 --> 00:22:00.033 running at the same time or in a new chat. 00:22:00.033 --> 00:22:04.133 If we want to ask for something different and kind of forget the previous conversation history 00:22:04.200 --> 00:22:07.333 we had here. 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 --> 00:22:26.400 And Codex will prompt us with different questions 00:22:26.400 --> 00:22:30.233 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 --> 00:22:47.200 I want to have puzzles. 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 --> 00:22:59.266 I want to have a better landing page so that a user can see their stats, 00:22:59.266 --> 00:23:03.900 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 --> 00:23:05.800 I want to generate a few different game modes, 00:23:05.800 --> 00:23:09.833 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 --> 00:23:36.066 We can have add bot game, add 00:23:36.066 --> 00:23:40.066 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 --> 00:23:46.433 Username. Profiles okay. 00:23:46.433 --> 00:23:49.833 Username. Login. Expand stats. 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 --> 00:23:55.233 Yes. Small 00:23:55.233 --> 00:23:58.500 bundled puzzled library that looks good and that we continue. 00:23:58.533 --> 00:24:00.300 Now while it's doing this, also mention 00:24:00.300 --> 00:24:03.333 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 --> 00:24:25.400 So if I want to look at the plan here, 00:24:25.400 --> 00:24:29.466 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 --> 00:24:37.700 But what I want to show you now is another mode that's super useful, 00:24:37.733 --> 00:24:41.300 that is going to get things done a lot more efficiently for us without us 00:24:41.300 --> 00:24:45.100 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 --> 00:25:00.666 Now this is kind of 00:25:00.666 --> 00:25:04.733 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 --> 00:25:28.033 Now, in order to use this effectively, 00:25:28.033 --> 00:25:32.000 you need to set a good goal and the conditions for the goal to be achieved. 00:25:32.033 --> 00:25:35.066 Now, in our case, we already have the plan so we can effectively 00:25:35.066 --> 00:25:38.300 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 --> 00:25:52.466 So for the goal I'm going to say okay, keep running 00:25:52.466 --> 00:25:55.666 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 --> 00:26:44.400 Now I want to really briefly discuss what a work tree is, 00:26:44.400 --> 00:26:48.233 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 --> 00:26:58.033 Okay, so I want new chat. 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 --> 00:27:10.266 Now the reason this is important is that if you want to run parallel agents at the same time, 00:27:10.266 --> 00:27:15.466 they should be working in their own copy of the repository or the project that you have. 00:27:15.533 --> 00:27:18.733 If they work on the same files, there can be conflicts 00:27:18.733 --> 00:27:22.633 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 --> 00:27:36.933 But if you do want to run parallel agents at the same time, 00:27:36.933 --> 00:27:39.933 you have multiple tasks going, this is what you would use. 00:27:39.933 --> 00:27:43.800 You have to configure the environment first, which you can ask Codex to help you do, 00:27:43.800 --> 00:27:47.800 and then you can change the branches and stuff in order to work on the different features. 00:27:47.800 --> 00:27:51.300 And now you'll have different agents because you can run multiple at the same time, 00:27:51.700 --> 00:27:54.633 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 --> 00:28:08.833 Now this is a code review that can automatically compare 00:28:08.833 --> 00:28:13.733 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 --> 00:28:18.800 So if I go to maybe this right now and I go slash review, 00:28:18.833 --> 00:28:22.000 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 --> 00:28:30.133 So if I go slash review right and then uncommitted changes 00:28:30.233 --> 00:28:34.633 it's going to start looking at all of the changes that it made here and automatically review 00:28:34.633 --> 00:28:39.300 them to make sure that they're good before we push them to get or before we commit them. 00:28:39.300 --> 00:28:43.333 This is a pretty useful feature that Codex has, and this is something you should always do 00:28:43.400 --> 00:28:47.600 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 --> 00:28:51.100 But if you're a developer, you'll understand the value 00:28:51.100 --> 00:28:55.400 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 --> 00:29:04.266 Right. 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 --> 00:29:10.866 Now this is less maybe, I don't know demo 00:29:10.866 --> 00:29:13.900 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 --> 00:29:29.433 Now, the reason why I'm going to run this prompt and show you the result, is that you need 00:29:29.433 --> 00:29:32.433 to understand that by default, 00:29:32.466 --> 00:29:36.433 Codex doesn't remember things that you worked on in the past. 00:29:36.433 --> 00:29:41.433 Anytime you create a new chat, what it's doing is reviewing anything that you have 00:29:41.433 --> 00:29:44.466 in your current repo, kind of trying to load in information 00:29:44.466 --> 00:29:47.866 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 --> 00:29:55.066 It won't know maybe preferences 00:29:55.066 --> 00:29:59.066 that you told it, and it can forget things because it doesn't remember by default. 00:29:59.100 --> 00:30:02.900 The only reason this actually just gave me a response is because it looked inside 00:30:02.900 --> 00:30:07.433 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 --> 00:30:23.833 The reason why I'm mentioning this is that you need to understand that 00:30:23.833 --> 00:30:27.800 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 --> 00:30:42.933 And it has to actually go and look through the different conversation history 00:30:42.933 --> 00:30:46.233 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 --> 00:30:57.333 The reason why I'm mentioning this is that you can fix this problem 00:30:57.333 --> 00:31:01.233 by creating something called an agent dot file. 00:31:01.233 --> 00:31:06.133 Now this is something that's common in all of your code base tools, CLI based tools, 00:31:06.166 --> 00:31:10.066 whatever AI agents where you can make effectively a memory file 00:31:10.066 --> 00:31:15.800 that will always be loaded into the prompt or into the model before you start working with it. 00:31:15.800 --> 00:31:17.533 Now this is a really good file to create, 00:31:17.533 --> 00:31:20.600 especially when you're working on larger projects with multiple people, 00:31:20.600 --> 00:31:25.133 because you can store preferences, different tools or stacks that you want to use. 00:31:25.200 --> 00:31:28.333 I wouldn't say credentials, but you can store just important 00:31:28.333 --> 00:31:31.400 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 --> 00:31:37.200 I would like you to create an agent file with all of the conventions 00:31:37.400 --> 00:31:39.666 for this project, specifically the tech stack 00:31:39.666 --> 00:31:43.266 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 --> 00:32:00.300 Now we're never going to forget or Codex will never forget because this is by default 00:32:00.300 --> 00:32:04.066 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 --> 00:32:09.900 So let's open this up and you can see that it gives us 00:32:09.900 --> 00:32:13.400 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 --> 00:32:39.000 If we look at the context, you can see the context is slightly 00:32:39.000 --> 00:32:42.333 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 --> 00:32:48.100 I know that's not the best explanation possible, but anything that you want to be kind of long 00:32:48.133 --> 00:32:51.100 term, persistent info that's going to be used all of the time, 00:32:51.100 --> 00:32:56.100 you want to put it in this agents MD file and tell Codex to create that for you. 00:32:56.100 --> 00:32:58.100 And you can continually update this 00:32:58.100 --> 00:33:02.466 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 --> 00:33:12.333 Now I'm not going to actually create these, but I'm just going to mention that they exist 00:33:12.400 --> 00:33:16.200 just like cloud code or other tools that you may have used, you can create scheduled 00:33:16.233 --> 00:33:19.933 tasks that run automatically for you, assuming your computer is on. 00:33:19.933 --> 00:33:24.500 So you can make a daily brief where every morning it opens your computer, searches 00:33:24.500 --> 00:33:26.000 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 --> 00:33:36.100 So if I do create via chat, for example, I can make it to set up a scheduled 00:33:36.133 --> 00:33:39.466 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 --> 00:33:52.400 Okay. So again you can make these. 00:33:52.400 --> 00:33:56.000 You can have them set to run and you can set this up to kind of automatically 00:33:56.000 --> 00:33:59.133 do things for you, which is useful if you want some automations. 00:33:59.133 --> 00:34:01.833 But for me I don't really need any. So I don't have those setup as of now. 00:34:01.833 --> 00:34:05.500 And then of course, you can search through all of your chats and a bunch of other stuff, 00:34:05.500 --> 00:34:10.733 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 --> 00:34:23.466 If you guys let me know in the comments that you want to see an advanced version of this 00:34:23.500 --> 00:34:27.900 that is going to wrap up this video, that was a pretty comprehensive overview of Codex, 00:34:27.933 --> 00:34:32.700 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.
