WEBVTT 00:00.540 --> 00:02.580 -: The first principle is giving direction, 00:02.580 --> 00:04.410 describing the desired style in detail 00:04.410 --> 00:06.723 or referencing a relevant persona. 00:07.560 --> 00:09.963 So, let's walk through this with text models. 00:11.010 --> 00:13.680 This is an example of a naive prompt. 00:13.680 --> 00:16.410 So, if we were looking for a pair of shoes 00:16.410 --> 00:17.970 that could fit any foot size, 00:17.970 --> 00:20.040 we want to brainstorm with ChatGPT, 00:20.040 --> 00:20.887 we could just write that out. 00:20.887 --> 00:23.137 "Can I have a list of 10 product names 00:23.137 --> 00:25.647 "for a pair of shoes that can fit any foot size?" 00:26.760 --> 00:28.770 And this does a reasonable job. 00:28.770 --> 00:30.360 You know, these names are pretty good. 00:30.360 --> 00:32.760 If you're just brainstorming, that's no big deal. 00:32.760 --> 00:35.250 You don't actually need prompt engineering. 00:35.250 --> 00:38.280 Now, if you were building a product 00:38.280 --> 00:40.770 that helped people brainstorm names, 00:40.770 --> 00:42.540 you need to work a little bit more on the prompt 00:42.540 --> 00:44.670 because that prompt is gonna be run hundreds 00:44.670 --> 00:46.650 or maybe thousands of times. 00:46.650 --> 00:48.504 So, this is prompt engineering, 00:48.504 --> 00:51.510 when you're working on the prompt to make it more reliable 00:51.510 --> 00:54.900 or to get it to give you more desired outputs. 00:54.900 --> 00:57.360 And this is an example of a prompt template 00:57.360 --> 01:00.360 that we came up with where we've really optimized it. 01:00.360 --> 01:02.910 We've used all of the five principles of prompt engineering, 01:02.910 --> 01:06.093 and we're gonna go through just the first principle today. 01:07.728 --> 01:10.980 This is the prompt template if you guys want to use that, 01:10.980 --> 01:13.020 and you can learn a lot from this prompt template 01:13.020 --> 01:14.730 to create your own prompt templates. 01:14.730 --> 01:16.650 But the main things to call out here 01:16.650 --> 01:18.300 is that this is reusable. 01:18.300 --> 01:20.430 So, no matter what type of product 01:20.430 --> 01:22.860 we're trying to generate names for, 01:22.860 --> 01:25.710 we can insert that product description in this template 01:25.710 --> 01:27.270 in these curly brackets. 01:27.270 --> 01:28.957 We also have this section where we say 01:28.957 --> 01:30.690 "in the style of a famous inventor," 01:30.690 --> 01:32.730 and that's a variable we can change. 01:32.730 --> 01:35.310 But there's also the rest of the template as well. 01:35.310 --> 01:37.200 And we can test different parts of this template, 01:37.200 --> 01:38.430 and I think that's really the key 01:38.430 --> 01:40.260 to understanding prompt engineering, 01:40.260 --> 01:43.620 which is to actually change some parts of this template 01:43.620 --> 01:46.593 and see how it responds to performance. 01:47.940 --> 01:49.680 Okay, so the first principle 01:49.680 --> 01:52.230 I promised to cover was giving direction. 01:52.230 --> 01:56.340 So, in this case, we have a specific part of the prompt 01:56.340 --> 01:58.530 that says, "In the style of," 01:58.530 --> 02:01.080 and then we have in this case Steve Jobs. 02:01.080 --> 02:02.400 And it doesn't have to be Steve Jobs. 02:02.400 --> 02:05.460 It could be anyone that we want to emulate the style of. 02:05.460 --> 02:07.207 But you can see here that when we say, 02:07.207 --> 02:10.740 "in the style of Steve Jobs," we get Steve Jobs-like names. 02:10.740 --> 02:14.220 So we have the iFitShoe, iAdapt, iUniversalStep, 02:14.220 --> 02:16.500 just like the iPod or iPhone. 02:16.500 --> 02:19.890 So again, we're describing the desired style in detail 02:19.890 --> 02:22.830 and we're referencing a relevant persona. 02:22.830 --> 02:25.620 The key is knowing what style to put in here. 02:25.620 --> 02:28.560 If you're a student of history or business or art, 02:28.560 --> 02:31.800 you can know who are the famous product namers in the past 02:31.800 --> 02:33.360 or you could do that research. 02:33.360 --> 02:36.570 You don't have to use someone as obvious as Steve Jobs, 02:36.570 --> 02:38.940 and I think that's where you get the key insight 02:38.940 --> 02:40.320 into this principle. 02:40.320 --> 02:41.610 Based on your domain knowledge, 02:41.610 --> 02:43.593 you can give it better direction. 02:45.370 --> 02:47.880 Okay, so let's look at the impact on results 02:47.880 --> 02:49.650 of changing one of these variables. 02:49.650 --> 02:52.110 If we change it from Steve Jobs to Elon Musk, 02:52.110 --> 02:53.520 we're gonna get different names. 02:53.520 --> 02:56.340 We get ShoeX, MarsFit, The Shoe Company, 02:56.340 --> 02:58.020 just like the Boring Company. 02:58.020 --> 02:59.310 If we change it to Walt Disney, 02:59.310 --> 03:01.680 it's Enchanted Slippers, Magic Step, Whimsoles, 03:01.680 --> 03:03.810 which is one I particularly like. 03:03.810 --> 03:06.120 And then Marc Jacobs in the fashion space, 03:06.120 --> 03:09.540 Morph by Marc, the Marc Jacobs Flexible Shoe, 03:09.540 --> 03:10.773 FlexForm Oxfords. 03:12.450 --> 03:14.970 The really interesting thing about the principles 03:14.970 --> 03:16.800 of prompt engineering is that they apply 03:16.800 --> 03:18.900 no matter what AI model you're prompting. 03:18.900 --> 03:21.720 So, if you look at image models, in this case, 03:21.720 --> 03:24.390 Stable Diffusion, we can do the same thing. 03:24.390 --> 03:26.730 So again, we're just prompting Stable Diffusion 03:26.730 --> 03:30.870 in this case, looking for a shoe that can fit any foot size. 03:30.870 --> 03:33.540 So we have our idea, 03:33.540 --> 03:34.830 we have our name, 03:34.830 --> 03:36.930 but now we're gonna enter an image of that product, 03:36.930 --> 03:38.790 and it does a pretty decent job. 03:38.790 --> 03:41.130 Some of these are kind of ugly, to be honest, 03:41.130 --> 03:43.770 but I kind of like the one in the bottom right. 03:43.770 --> 03:45.360 It looks like an astronaut shoe. 03:45.360 --> 03:48.210 It does look like it could fit any foot size. 03:48.210 --> 03:52.080 Now, here it is an example that's been prompt engineered, 03:52.080 --> 03:54.690 as we've applied all of the five principles to it 03:54.690 --> 03:56.340 and we're gonna specifically call out 03:56.340 --> 03:57.933 where we gave direction. 03:59.460 --> 04:00.960 This is the prompt template. 04:00.960 --> 04:02.910 We have the prototype, we have style details, 04:02.910 --> 04:04.230 and then we have designed by artists. 04:04.230 --> 04:07.230 Again, we're using the role playing section again. 04:07.230 --> 04:11.640 And then we have a few aspects related to format. 04:11.640 --> 04:13.830 So we have product photography, extremely details, 04:13.830 --> 04:15.360 studio light, et cetera. 04:15.360 --> 04:16.260 If you use this template, 04:16.260 --> 04:18.160 you will get a pretty reliable result. 04:19.530 --> 04:21.630 Now, the part where we're giving direction 04:21.630 --> 04:22.950 is in this part here. 04:22.950 --> 04:26.070 We've said we want it to be scary, beautiful, 04:26.070 --> 04:28.350 platemail armor, sleek iridescent detail, 04:28.350 --> 04:30.450 designed by Ridley Scott, "Alien," 04:30.450 --> 04:32.520 as in from the "Alien" movies. 04:32.520 --> 04:33.600 You can see it kind of looks 04:33.600 --> 04:36.120 like the Xenomorph's exterior hide, 04:36.120 --> 04:38.100 but it's neon pink and blue. 04:38.100 --> 04:39.750 And that's really exciting 04:39.750 --> 04:41.820 because we can change this variable. 04:41.820 --> 04:43.800 We can get different results. 04:43.800 --> 04:45.750 And again, we're giving it some direction. 04:45.750 --> 04:49.050 In this case, we're actually changing the style details. 04:49.050 --> 04:51.780 Now, you don't have to go with what I went with. 04:51.780 --> 04:53.340 You could change that to anything else. 04:53.340 --> 04:55.877 Like, here is a shoe designed by Salvador Dali. 04:55.877 --> 04:58.350 Here's a shoe designed by Van Gogh. 04:58.350 --> 05:00.840 And then this last one, which is my favorite, 05:00.840 --> 05:03.847 is based on the famous Japanese block painting, 05:03.847 --> 05:05.040 "The Great Wave." 05:05.040 --> 05:06.720 Whatever it is you decide to do, 05:06.720 --> 05:09.541 giving direction is the first thing you should try, 05:09.541 --> 05:13.230 'cause if you can steer the model towards something 05:13.230 --> 05:15.420 that's unique and original and create it, 05:15.420 --> 05:17.790 then you're gonna get much better results 05:17.790 --> 05:20.703 that are specific to your use case.
