1 00:00:00,080 --> 00:00:00,320 Now. 2 00:00:00,320 --> 00:00:04,240 Steps three and four of the set of instructions are optional. 3 00:00:04,440 --> 00:00:10,320 I strongly recommend that you get an account with OpenAI if you don't have one already, so that we 4 00:00:10,320 --> 00:00:15,000 can use the most powerful models on the planet, and OpenAI is a good one to start with. 5 00:00:15,200 --> 00:00:16,440 But you don't need to. 6 00:00:16,600 --> 00:00:20,880 It requires a payment $5 up front, and you might not want to spend that. 7 00:00:20,880 --> 00:00:24,080 And you can use free models throughout this course. 8 00:00:24,080 --> 00:00:27,200 You can use Gemini or you can use llama. 9 00:00:27,200 --> 00:00:29,760 And there are detailed instructions for how to do it. 10 00:00:29,760 --> 00:00:33,080 And I will have an example lab as well. 11 00:00:33,240 --> 00:00:38,280 But assuming that you do want to go ahead and set up an OpenAI account, you may already have one as 12 00:00:38,280 --> 00:00:38,760 well. 13 00:00:38,760 --> 00:00:39,600 Let's do that. 14 00:00:39,600 --> 00:00:44,200 That is step three, and feel free to skip this or just watch what I do if you don't want to. 15 00:00:44,360 --> 00:00:46,000 So you go to a web browser. 16 00:00:46,000 --> 00:00:47,600 I've got an incognito tab here. 17 00:00:47,600 --> 00:00:55,400 So because I'm already logged into OpenAI, but you go to platform OpenAI, that is where you come to 18 00:00:55,440 --> 00:01:03,040 the kind of the API side of OpenAI, not to use ChatGPT, but to have your own account to use the API. 19 00:01:03,510 --> 00:01:05,070 and that's an important point. 20 00:01:05,110 --> 00:01:10,790 Some people are confused about the fact that there is ChatGPT the product which you can interact with 21 00:01:10,790 --> 00:01:15,750 and which has a paid plan for like $20 a month and an even higher tier paid plan. 22 00:01:15,990 --> 00:01:23,630 And then separate to that, there is an API, the OpenAI API, for connecting to the model directly. 23 00:01:23,630 --> 00:01:27,990 And people, some people are confused about that and say, hey, if I'm paying for one, why can't I 24 00:01:27,990 --> 00:01:28,630 have the other? 25 00:01:28,790 --> 00:01:31,710 Luckily, I've written a guide about exactly that. 26 00:01:31,750 --> 00:01:35,630 There's a guide called Technical Foundations, which you'll find in the guides folder. 27 00:01:35,630 --> 00:01:40,190 It takes you through some of the foundational information to help you navigate through some of these 28 00:01:40,190 --> 00:01:40,990 concepts. 29 00:01:40,990 --> 00:01:49,150 And I explain very clearly the difference between the product ChatGPT and using the API from an AI engineer's 30 00:01:49,190 --> 00:01:50,030 point of view. 31 00:01:50,030 --> 00:01:52,790 So do please read that if you've got any confusion. 32 00:01:52,990 --> 00:01:57,230 But assuming that that's that's obvious to you, then then great, come here. 33 00:01:57,270 --> 00:01:58,830 Come to platform OpenAI. 34 00:01:59,590 --> 00:02:01,950 And the first thing to do is to click sign up. 35 00:02:01,950 --> 00:02:08,340 And you can then come in and use like your your Google auth any or Microsoft account or an Apple account, 36 00:02:08,340 --> 00:02:10,540 or just create an account with an email address. 37 00:02:10,660 --> 00:02:15,140 I think people that are coming internationally outside the US, you might need to click a button like 38 00:02:15,140 --> 00:02:17,220 create organization or something first. 39 00:02:17,260 --> 00:02:20,980 You might need to click through some screen before you get to create your account, but it should be 40 00:02:20,980 --> 00:02:22,700 pretty obvious you should get here. 41 00:02:22,740 --> 00:02:24,020 Sign up for an account. 42 00:02:24,020 --> 00:02:25,660 So far, it's completely free. 43 00:02:25,860 --> 00:02:28,020 The money will come in just a second. 44 00:02:28,060 --> 00:02:29,660 The $5 spend. 45 00:02:29,900 --> 00:02:32,820 Uh, let's let's, uh, come back once you've set up your account. 46 00:02:32,820 --> 00:02:33,180 Okay. 47 00:02:33,220 --> 00:02:39,980 So this is what you see once you come to platform and once you've signed in with an account, and the 48 00:02:39,980 --> 00:02:45,460 navigation is just a little bit confusing, but you have to be aware that at the top here there's dashboard. 49 00:02:45,460 --> 00:02:47,820 And over on the right there's settings. 50 00:02:48,060 --> 00:02:53,700 And the first thing to do is to go over to settings, which is where the billing information is, and 51 00:02:53,700 --> 00:02:57,380 go to settings and then come down to billing right here. 52 00:02:57,780 --> 00:03:02,220 And this is where you get to put a balance on OpenAI. 53 00:03:02,580 --> 00:03:08,570 OpenAI is a pay as you go model, which means you put down an amount of money and then you draw down 54 00:03:08,570 --> 00:03:11,210 against that over time and you only spend. 55 00:03:11,250 --> 00:03:13,410 Tiny amounts of money on this course. 56 00:03:13,410 --> 00:03:17,370 We will spend fractions of a cent, typically for each of our projects. 57 00:03:17,370 --> 00:03:23,450 Except where I tell you otherwise, you should always track your your spend always come back here. 58 00:03:23,450 --> 00:03:28,570 The nice thing about this is that because it's a pay as you go model, you're always paying up front. 59 00:03:28,570 --> 00:03:33,050 You're not likely to get some kind of surprise as long as you only top up with a small amount. 60 00:03:33,050 --> 00:03:37,090 There are some some other services like AWS where it doesn't work that way, which I don't like. 61 00:03:37,130 --> 00:03:41,130 This one is better because you get to be in complete control of your spend. 62 00:03:41,170 --> 00:03:43,210 Nonetheless, you should come back and have a look at it. 63 00:03:43,450 --> 00:03:45,890 You should always have auto recharge off. 64 00:03:45,930 --> 00:03:47,850 You don't want it to automatically recharge. 65 00:03:47,850 --> 00:03:48,530 Don't press that. 66 00:03:48,530 --> 00:03:50,170 Enable auto recharge button. 67 00:03:50,170 --> 00:03:54,650 You don't want it automatically billing to your credit card, unless this is something that you're in 68 00:03:54,650 --> 00:03:56,610 production and you know exactly what you're doing. 69 00:03:56,850 --> 00:04:00,930 So the first thing you do when you come in here, you should see zero credit balance. 70 00:04:00,930 --> 00:04:03,970 And you will want to press the Add to credit balance button. 71 00:04:03,970 --> 00:04:06,210 And you'll want to to type in an amount there. 72 00:04:06,210 --> 00:04:08,370 And you'll want to select a payment method. 73 00:04:08,530 --> 00:04:14,270 And then once you've done that, you would then add that amount and sorry, $5 is the minimum. 74 00:04:14,270 --> 00:04:15,550 You don't need to spend $10. 75 00:04:15,590 --> 00:04:17,750 $5 is the minimum payment amount. 76 00:04:17,790 --> 00:04:19,950 You will then draw down and that lasts a year. 77 00:04:20,270 --> 00:04:23,990 So you've got you've got plenty of time to spend that $5. 78 00:04:23,990 --> 00:04:29,870 You need to make sure that your payment methods includes a valid credit card that you can charge against. 79 00:04:29,910 --> 00:04:32,230 Otherwise, OpenAI will throw various errors. 80 00:04:32,230 --> 00:04:35,390 So make sure that you add a proper payment method which it can use. 81 00:04:35,670 --> 00:04:41,310 And I should mention a lot of students do have problems with payments not being accepted, getting declined 82 00:04:41,670 --> 00:04:42,830 through through OpenAI. 83 00:04:42,950 --> 00:04:48,150 And it's worth pointing out that almost always most of the time, any time that I've been aware of that 84 00:04:48,150 --> 00:04:55,390 problem is with your credit card not accepting OpenAI's charge as an international vendor, OpenAI is 85 00:04:55,390 --> 00:04:57,270 happy to take your money if you let it. 86 00:04:57,310 --> 00:04:59,630 It's unlikely to be a problem with OpenAI. 87 00:04:59,910 --> 00:05:05,310 It's more likely that your credit card company, for whatever reason, is refusing an international 88 00:05:05,310 --> 00:05:05,910 charge. 89 00:05:05,910 --> 00:05:10,470 And so you might need to go into your to your bank account and select something which enables that kind 90 00:05:10,470 --> 00:05:11,070 of charge. 91 00:05:11,110 --> 00:05:13,260 Perhaps something to look out for. 92 00:05:13,420 --> 00:05:17,740 Otherwise, if you if you really can't get past this and can't get a balance on there, then you can 93 00:05:17,740 --> 00:05:19,100 contact OpenAI support. 94 00:05:19,100 --> 00:05:20,700 They're actually really responsive. 95 00:05:21,140 --> 00:05:21,660 Okay. 96 00:05:21,700 --> 00:05:23,060 But let me assume you've done this. 97 00:05:23,060 --> 00:05:26,060 This is now showing $5 and it's looking great. 98 00:05:26,060 --> 00:05:29,540 You've got a good payment method associated with your account. 99 00:05:29,580 --> 00:05:31,900 We're ready to set up an API key. 100 00:05:32,060 --> 00:05:32,500 Okay. 101 00:05:32,540 --> 00:05:34,180 So you're still in settings. 102 00:05:34,220 --> 00:05:36,420 You're still seeing this menu up here. 103 00:05:36,420 --> 00:05:42,500 And the first thing to do is to select API keys up here making sure you're under the organization heading. 104 00:05:42,500 --> 00:05:44,740 You're right up here API keys. 105 00:05:44,900 --> 00:05:45,780 And here you go. 106 00:05:45,820 --> 00:05:48,660 You can see that that I have some API keys. 107 00:05:48,820 --> 00:05:50,740 And you're going to make one yourself. 108 00:05:50,780 --> 00:05:53,500 Right now these are your API keys. 109 00:05:53,500 --> 00:05:57,780 And it's super important to be careful about what you do next. 110 00:05:58,060 --> 00:06:02,500 You're going to press the Create new Secret key button like so. 111 00:06:03,020 --> 00:06:05,300 You're going to want to create a new secret key. 112 00:06:05,340 --> 00:06:08,900 It is owned by you not service account. 113 00:06:09,060 --> 00:06:15,170 You can give it whatever name you want, but something that you remember, like, uh, LM engineering 114 00:06:16,090 --> 00:06:16,650 key. 115 00:06:17,130 --> 00:06:20,450 And now be careful with this for the project. 116 00:06:20,450 --> 00:06:26,010 Select default project because you don't want to have any extra constraints. 117 00:06:26,010 --> 00:06:31,050 If people if you do anything clever here that that constrains it in some way, then you might get errors 118 00:06:31,050 --> 00:06:31,690 later. 119 00:06:31,690 --> 00:06:38,050 So just have default project, which means any project can access this and leave permissions at all. 120 00:06:38,170 --> 00:06:41,410 And then you're going to press the Create secret key button. 121 00:06:41,690 --> 00:06:46,410 And when you do that which I will do it now it will come up with a key like this. 122 00:06:46,650 --> 00:06:49,090 And fear not I'm going to delete this key right afterwards. 123 00:06:49,370 --> 00:06:49,610 Aha. 124 00:06:49,930 --> 00:06:54,090 Uh this key is your key with OpenAI. 125 00:06:54,130 --> 00:06:57,610 It's your way to link your code to using OpenAI. 126 00:06:57,930 --> 00:07:03,010 And it begins ESC hyphen, hyphen. 127 00:07:03,010 --> 00:07:05,490 And then this long thing right here. 128 00:07:05,730 --> 00:07:07,290 And that is your secret key. 129 00:07:07,450 --> 00:07:10,210 And that's something which we're going to be using in our code. 130 00:07:10,410 --> 00:07:14,930 And if you get this wrong, if you type, if you, if you change one of these numbers or one of these 131 00:07:14,930 --> 00:07:17,000 letters, it's like a password. 132 00:07:17,160 --> 00:07:18,440 Everything has to be right. 133 00:07:18,440 --> 00:07:20,880 If something's wrong, it's not going to work. 134 00:07:21,280 --> 00:07:23,880 So copy it into your clipboard by pressing copy. 135 00:07:23,920 --> 00:07:24,600 It's now copied. 136 00:07:24,600 --> 00:07:26,520 So when you press paste, it's going to paste. 137 00:07:26,520 --> 00:07:28,560 And in a minute we're going to paste it somewhere. 138 00:07:28,600 --> 00:07:34,520 And please now don't don't paste it somewhere else first and then copy it again or anything that might 139 00:07:34,520 --> 00:07:35,480 mess with the key. 140 00:07:35,640 --> 00:07:38,880 Let it be in your clipboard in pristine shape. 141 00:07:38,880 --> 00:07:39,920 We're not going to change it. 142 00:07:39,920 --> 00:07:45,000 We're going to paste it exactly as it is into our actual inter cursor. 143 00:07:45,000 --> 00:07:46,680 So keep it like this. 144 00:07:46,720 --> 00:07:48,600 In fact, you don't even need to press the done button yet. 145 00:07:48,600 --> 00:07:50,200 You can keep this screen up here. 146 00:07:50,200 --> 00:07:54,120 We're going to go back to cursor and put this in cursor right away. 147 00:07:54,240 --> 00:07:55,240 Let's go do that. 148 00:07:55,240 --> 00:07:57,480 So here I am back in cursor. 149 00:07:57,520 --> 00:08:02,280 By the way if you have one of your terminal screens appearing like this, you can close it just by pressing 150 00:08:02,280 --> 00:08:03,240 the X button there. 151 00:08:03,240 --> 00:08:05,320 So you've got nice clean screen. 152 00:08:06,000 --> 00:08:06,600 Okay. 153 00:08:06,960 --> 00:08:14,440 What we're going to do now is create a file called the file, which is a file that contains your secrets. 154 00:08:14,680 --> 00:08:17,680 And it's super important that you do this carefully. 155 00:08:17,680 --> 00:08:20,350 It's got to be right or things ain't going to work. 156 00:08:20,590 --> 00:08:20,910 So? 157 00:08:20,910 --> 00:08:22,110 So this needs to be right. 158 00:08:22,310 --> 00:08:26,950 The EMV file is a new file we're going to create, which has to be at the top level. 159 00:08:26,950 --> 00:08:32,230 It has to be a file within LM engineering not inside any of these directories. 160 00:08:32,390 --> 00:08:37,590 So what we can do is we can get this little blank space just here underneath the bottom of this list 161 00:08:37,590 --> 00:08:38,390 of files. 162 00:08:38,390 --> 00:08:41,550 You can right click there and say new file. 163 00:08:41,670 --> 00:08:43,670 And you can see it's now giving me a new file. 164 00:08:43,670 --> 00:08:44,790 And you can just double check. 165 00:08:44,790 --> 00:08:48,790 It's at the same top level as all these other top level files. 166 00:08:48,790 --> 00:08:54,790 And I'm going to call it it's going to be called exactly a period dot like that. 167 00:08:55,030 --> 00:09:04,030 And then the letter E and the letter n and the letter v e v and it can't be called dot EMV dot txt. 168 00:09:04,070 --> 00:09:06,750 It can't be called EMV in your name. 169 00:09:06,790 --> 00:09:09,710 It can't be called EMV dot it. 170 00:09:10,150 --> 00:09:14,750 In case you didn't get the message, it's got to be called EMV and only that and it's got to be in the 171 00:09:14,750 --> 00:09:16,550 project root in this top folder. 172 00:09:16,550 --> 00:09:17,670 And there it is. 173 00:09:17,990 --> 00:09:21,340 That is the right place to be Okay. 174 00:09:21,900 --> 00:09:25,580 And now what I'm going to put in here is going to be my open AI key. 175 00:09:25,700 --> 00:09:27,180 And here's how you do it. 176 00:09:27,180 --> 00:09:33,260 You have to type open AI underscore API underscore key. 177 00:09:34,300 --> 00:09:40,740 And it's got to be exactly this open AI underscore API underscore key. 178 00:09:41,100 --> 00:09:43,180 It's got to be in block capitals. 179 00:09:43,340 --> 00:09:47,260 It's not this it's not open API key. 180 00:09:47,420 --> 00:09:49,860 It's open AI API key. 181 00:09:50,140 --> 00:09:52,180 Now you wonder why I'm going on about this. 182 00:09:52,180 --> 00:09:57,380 I get more than a thousand emails every couple of during every few weeks. 183 00:09:57,380 --> 00:10:01,500 I get that many emails from people that have mistyped these words. 184 00:10:01,500 --> 00:10:03,420 So don't do that. 185 00:10:03,540 --> 00:10:06,900 Spell it open AI API key exactly like this. 186 00:10:07,420 --> 00:10:11,980 Uh, then equals it's open ai API key equals. 187 00:10:11,980 --> 00:10:14,620 And then you're going to press paste. 188 00:10:14,780 --> 00:10:21,180 And when you do paste it's going to paste in that key that you copied from the open AI screen. 189 00:10:21,180 --> 00:10:22,220 Let's check it out. 190 00:10:22,260 --> 00:10:23,600 Look it's open OpenAI. 191 00:10:23,720 --> 00:10:26,360 API key equals sq. 192 00:10:26,680 --> 00:10:27,880 Proj dash. 193 00:10:28,080 --> 00:10:30,280 And then this long funny thing. 194 00:10:30,680 --> 00:10:32,960 And there's nothing crazy at the end of it. 195 00:10:33,000 --> 00:10:35,360 We haven't pasted in an extra space. 196 00:10:35,400 --> 00:10:36,280 An extra empty. 197 00:10:36,320 --> 00:10:37,320 We've been careful. 198 00:10:37,400 --> 00:10:39,360 It is exactly this. 199 00:10:39,840 --> 00:10:45,040 Now, that white blob just to the right there means that I haven't yet saved this file. 200 00:10:45,160 --> 00:10:46,120 It's not been saved. 201 00:10:46,120 --> 00:10:50,120 It's not on the disk, which means it's empty as far as my computer is concerned. 202 00:10:50,200 --> 00:10:57,680 So I have to press command S Ctrl s on a PC, command S on a mac or file save to save it, and the white 203 00:10:57,720 --> 00:10:59,200 blob goes away. 204 00:10:59,200 --> 00:11:01,080 And that means it's now saved. 205 00:11:01,200 --> 00:11:05,880 This is now in the file I get, I get, I get hundreds of emails from people that haven't saved the 206 00:11:05,880 --> 00:11:06,240 files. 207 00:11:06,320 --> 00:11:07,000 Saved the file. 208 00:11:07,400 --> 00:11:10,720 You'll see that there is a little stop sign next to it. 209 00:11:10,720 --> 00:11:14,520 I also get hundreds of emails from people that are worried about that stop sign. 210 00:11:14,520 --> 00:11:17,120 But that stop sign is actually good news. 211 00:11:17,120 --> 00:11:21,280 That stop sign is cursor telling you if you hover over it, it will tell you. 212 00:11:21,320 --> 00:11:25,400 It's telling you that AI features are disabled for this file. 213 00:11:25,750 --> 00:11:29,310 And the reason for that is that this file contains your secrets. 214 00:11:29,310 --> 00:11:34,430 This contains your precious key that connects you to OpenAI and to your credit card. 215 00:11:34,670 --> 00:11:36,910 And we don't want that leaking out. 216 00:11:36,950 --> 00:11:42,510 And particularly we don't want cursor sending this off to different AI to get some sort of information 217 00:11:42,510 --> 00:11:43,030 on it. 218 00:11:43,150 --> 00:11:45,750 So as a result, cursor is saying, hey, hands off. 219 00:11:45,790 --> 00:11:47,550 I'm I'm not going to touch this file. 220 00:11:47,550 --> 00:11:50,750 I'm not going to do AI suggestions for this file. 221 00:11:50,750 --> 00:11:53,110 This file is secretly just for you. 222 00:11:53,110 --> 00:11:54,910 So we like to see that stop sign. 223 00:11:54,910 --> 00:11:56,110 That is good news. 224 00:11:56,150 --> 00:11:58,670 Look out for it in anything with secrets in it. 225 00:11:58,670 --> 00:12:00,310 Like the EMV file. 226 00:12:00,630 --> 00:12:02,790 All right I think I belabored this one enough. 227 00:12:02,830 --> 00:12:04,270 You've got a EMV file. 228 00:12:04,270 --> 00:12:06,190 It's called exactly EMV. 229 00:12:06,350 --> 00:12:07,870 It's in your project root. 230 00:12:07,870 --> 00:12:08,950 In the top level. 231 00:12:09,070 --> 00:12:13,110 It says OpenAI API key in block capitals equals. 232 00:12:13,110 --> 00:12:19,950 And then it's got this key right here that you have taken from your your actual API key that you took 233 00:12:19,950 --> 00:12:20,710 from OpenAI. 234 00:12:20,710 --> 00:12:22,030 And you pasted it in here. 235 00:12:22,070 --> 00:12:23,430 Congratulations. 236 00:12:23,430 --> 00:12:27,550 You've got through the hardest part of the whole course getting the API key in there. 237 00:12:27,590 --> 00:12:28,630 Let's move on.
