WEBVTT 1 00:00:02.340 --> 00:00:07.460 With introductions, hello world, and a bit of 2 00:00:07.460 --> 00:00:12.800 basic information behind us, we now are ready 3 00:00:12.800 --> 00:00:16.060 to tackle the four main AI concepts to 4 00:00:16.060 --> 00:00:17.080 learn as a developer. 5 00:00:18.000 --> 00:00:20.760 And this is what will be the main 6 00:00:20.760 --> 00:00:22.980 part of the rest of this course. 7 00:00:22.980 --> 00:00:28.440 As I've mentioned before, there's, in my opinion, 8 00:00:28.660 --> 00:00:33.040 four main AI concepts, those being chat, tool 9 00:00:33.040 --> 00:00:35.760 calling, structured output, and rack. 10 00:00:37.180 --> 00:00:40.220 In this video, I will just briefly mention 11 00:00:40.220 --> 00:00:43.180 what they are, so you are aware, and 12 00:00:43.180 --> 00:00:47.940 then there will be different sections dedicated for 13 00:00:47.940 --> 00:00:51.080 going deeper into all four of these. 14 00:00:52.700 --> 00:00:55.300 So the first one being chat, and you 15 00:00:55.300 --> 00:00:58.480 might think, well, I'm not building a chatbot 16 00:00:58.480 --> 00:00:59.400 or anything. 17 00:00:59.880 --> 00:01:05.460 Chat is just a common word for a 18 00:01:05.460 --> 00:01:07.520 request response capability. 19 00:01:08.440 --> 00:01:10.780 It doesn't need to be question and answer, 20 00:01:10.780 --> 00:01:15.540 it can also be action and response back 21 00:01:15.540 --> 00:01:16.820 to that action, and so on. 22 00:01:17.380 --> 00:01:19.760 So you could make a chatbot, but it 23 00:01:19.760 --> 00:01:21.760 could also just run behind the scenes every 24 00:01:21.760 --> 00:01:25.940 time some webhook is being triggered in your 25 00:01:25.940 --> 00:01:26.500 system. 26 00:01:26.960 --> 00:01:29.540 You need to get some data out from 27 00:01:29.540 --> 00:01:33.380 a system and paste it into another system. 28 00:01:34.900 --> 00:01:39.100 So chat is the bare bones of what 29 00:01:39.100 --> 00:01:40.220 we're going to do here. 30 00:01:40.300 --> 00:01:43.200 We're going to talk about conversations, where we 31 00:01:43.200 --> 00:01:48.140 have back and forwards, instructions, and prompt engineering 32 00:01:48.140 --> 00:01:49.260 in that section. 33 00:01:52.420 --> 00:01:56.640 The next concept is tool calling, and that's 34 00:01:56.640 --> 00:01:59.180 the ability to call user code. 35 00:02:00.100 --> 00:02:02.700 So we can have live interactions with other 36 00:02:02.700 --> 00:02:05.240 systems, or we can ask for more data. 37 00:02:05.240 --> 00:02:09.460 So tools can either be informational, meaning I 38 00:02:09.460 --> 00:02:12.140 need to go up and grab some data, 39 00:02:12.380 --> 00:02:14.500 like a web search, or it can be 40 00:02:14.500 --> 00:02:17.340 an action tool that can go in and 41 00:02:17.340 --> 00:02:22.860 make, for example, some kind of order in 42 00:02:22.860 --> 00:02:25.400 an invoice system, or in a back end 43 00:02:25.400 --> 00:02:27.840 of a webshop, or something for that. 44 00:02:28.620 --> 00:02:30.000 We can make them ourselves. 45 00:02:30.480 --> 00:02:35.300 We can use the MCP protocol to use 46 00:02:35.300 --> 00:02:35.800 tools. 47 00:02:36.200 --> 00:02:39.940 We can use other agents as tools. 48 00:02:40.500 --> 00:02:44.460 So it's a very, very important concept, so 49 00:02:44.460 --> 00:02:46.180 it has its own section with a lot 50 00:02:46.180 --> 00:02:47.120 of details in it. 51 00:02:48.360 --> 00:02:51.100 The third concept is structured output. 52 00:02:51.760 --> 00:02:54.340 Some people put that in together with chat. 53 00:02:54.760 --> 00:02:57.220 I find it so important and one of 54 00:02:57.220 --> 00:03:01.380 the most used of the features, so I 55 00:03:01.380 --> 00:03:02.960 put it in its own section. 56 00:03:03.660 --> 00:03:06.820 So structured output is more about whenever we 57 00:03:06.820 --> 00:03:11.040 saw hello world, we saw that sometimes it 58 00:03:11.040 --> 00:03:13.660 said the capital of France is Paris, other 59 00:03:13.660 --> 00:03:15.480 times it just said the word Paris, and 60 00:03:15.480 --> 00:03:15.940 so on. 61 00:03:16.240 --> 00:03:18.580 So we need to steer the model even 62 00:03:18.580 --> 00:03:20.300 more when we get data back. 63 00:03:20.960 --> 00:03:23.760 So we often don't just want text or 64 00:03:23.760 --> 00:03:24.560 markdown back. 65 00:03:24.680 --> 00:03:27.340 We actually want some structure in it, and 66 00:03:27.340 --> 00:03:29.620 that is what structured output gives, in that 67 00:03:29.620 --> 00:03:30.920 it can give it back as JSON. 68 00:03:32.140 --> 00:03:34.840 There's not much more to it, but it's 69 00:03:34.840 --> 00:03:37.920 very important that it's being learned, and also 70 00:03:37.920 --> 00:03:40.040 how you steer structured output. 71 00:03:42.400 --> 00:03:45.980 The final concept is the biggest one, meaning 72 00:03:45.980 --> 00:03:48.880 that while it's one of the first that 73 00:03:48.880 --> 00:03:53.380 came along, being Retrieval Augmented Generation, or RAC 74 00:03:53.380 --> 00:03:57.180 for short, is that we can give our 75 00:03:57.180 --> 00:03:57.760 own data. 76 00:03:58.360 --> 00:04:00.780 So AIs know a lot. 77 00:04:01.180 --> 00:04:03.140 They can know capital of France. 78 00:04:03.280 --> 00:04:05.860 They can know every little detail around the 79 00:04:05.860 --> 00:04:10.380 world, but they cannot talk with your company 80 00:04:10.380 --> 00:04:14.140 data, your personal data, and so on, without 81 00:04:14.140 --> 00:04:16.800 us giving it the data up front. 82 00:04:17.640 --> 00:04:20.459 And that is what RAC is, that we 83 00:04:20.459 --> 00:04:23.360 begin to take our own data, put them 84 00:04:23.360 --> 00:04:27.680 into vector stores, do similarity searches on them, 85 00:04:27.880 --> 00:04:28.720 and so on. 86 00:04:30.360 --> 00:04:32.600 There's a lot of concept in that area, 87 00:04:32.660 --> 00:04:35.360 so it's one of the bigger sections, but 88 00:04:35.360 --> 00:04:39.360 we will go into every single little detail 89 00:04:39.360 --> 00:04:41.400 so you can be successful with RAC as 90 00:04:41.400 --> 00:04:41.640 well. 91 00:04:42.660 --> 00:04:46.280 So that's the four main concepts which we'll 92 00:04:46.280 --> 00:04:47.200 now dive into.
