WEBVTT 00:00.160 --> 00:06.000 One of the things that's really nice about Cru is that it has a very flexible, lightweight approach 00:06.000 --> 00:08.680 to interacting with underlying LMS. 00:09.000 --> 00:16.640 It uses a framework called Lite LM under the hood, which it uses to interact with with the actual providers 00:16.640 --> 00:18.200 and with the LMS themselves. 00:18.240 --> 00:21.320 And I love Lite LM because it's so simple. 00:21.320 --> 00:22.560 It's so vanilla. 00:22.840 --> 00:27.200 You may know I have a somewhat love hate relationship with Lang Chain, which comes with with a fair 00:27.200 --> 00:30.000 amount of, of, uh, of structure to it. 00:30.040 --> 00:33.040 Lite LM is almost the other extreme where there's almost nothing there. 00:33.040 --> 00:37.040 You can just immediately connect with any LM you can imagine. 00:37.240 --> 00:40.640 And that really is reflected in the way it's used in Cru. 00:40.680 --> 00:46.520 Within Cru, you can just create an LM, you pass in a model name, and the structure is that it should 00:46.520 --> 00:49.520 have the provider's name followed by a slash followed by the model. 00:49.640 --> 00:55.520 And you can just use that to to be working with GPT four or mini with Claude through anthropic you can 00:55.520 --> 01:00.240 use three, five, three, seven, whatever you want Gemini flash, grok with a Q. 01:00.400 --> 01:03.000 And you could also use grok with a K in the same way. 01:03.280 --> 01:07.960 Olama if you're running the model locally, that's how you'd set it up and supply a base URL. 01:08.440 --> 01:16.100 And if you wanted to use Open Router, which itself is a kind of abstraction onto other LMS, but it's 01:16.100 --> 01:17.540 an actual service running. 01:17.540 --> 01:21.500 Then this is how you would configure Open Router as an example. 01:21.660 --> 01:28.780 But really the idea is very lightweight, very flexible, allows you to to really connect and switch 01:28.820 --> 01:33.060 around whichever models are running underneath your crew. 01:33.300 --> 01:39.380 And I would argue that in this way, crew really has an edge over open AI agents SDK, that this is 01:39.380 --> 01:41.540 really flexible and simple and I love it. 01:42.180 --> 01:49.740 And so the final topic before we get to do some coding and some crew making is to talk about crew AI 01:49.980 --> 01:50.940 projects. 01:51.340 --> 01:58.340 So in previous weeks we have just been coding within Python notebooks within cursor. 01:58.380 --> 02:01.180 And then occasionally we've gone to to real Python modules. 02:01.340 --> 02:03.820 Crew AI doesn't work that way with QR. 02:03.860 --> 02:11.980 You do need to work with Python code, and in fact cry builds an entire project and directory structure 02:11.980 --> 02:13.660 for each of your crews. 02:13.820 --> 02:18.380 So it comes with a bit more scaffolding than than we're used to. 02:18.580 --> 02:21.940 And there's a particular way that you need to use it. 02:21.980 --> 02:27.400 Now, the crew AI framework itself is already actually installed because I typed this command here you've 02:27.440 --> 02:28.760 tool install crew I. 02:28.880 --> 02:34.200 And that means that when you've cloned the repo you've already got the crew AI framework right there. 02:34.360 --> 02:38.280 But when you want to create a new project, you actually want a crew of your own. 02:38.320 --> 02:46.800 You type this command crew, I create crew, my crew or my project or whatever to create that project. 02:47.400 --> 02:53.760 And by the way, as a side note, you could say crew, I create flow, my project if you wanted to use 02:53.760 --> 02:58.640 the flow idea, the workflows, the more fixed workflows rather than a crew. 02:58.760 --> 03:00.480 But we're going to be sticking with crews. 03:00.520 --> 03:03.440 So crew I create crew my crew. 03:03.800 --> 03:10.400 And what that does is it's going to create a whole directory structure that's going to appear immediately. 03:10.560 --> 03:14.640 There's there's going to be at the top, my crew or my project, whatever you call it. 03:15.000 --> 03:21.880 And then a subdirectory source src and within that subdirectory will be the name of your project again, 03:21.920 --> 03:23.160 my crew or whatever. 03:23.680 --> 03:26.120 And then under that it's a bit nested. 03:26.160 --> 03:31.640 Under that will be a directory called config which is where you put your YAML files. 03:31.640 --> 03:32.240 And we'll see. 03:32.240 --> 03:38.420 In particular by default there'll be an agent's YAML and a task's YAML, which is where we can put our 03:38.420 --> 03:40.780 configuration for our agents and tasks. 03:41.260 --> 03:43.700 And then there's a module crew.py. 03:44.100 --> 03:49.180 And that module is the one I just showed you, which is where it all comes together with the decorators 03:49.340 --> 03:52.340 and the way the place we actually create our crew. 03:52.780 --> 03:55.100 And then there's a module called main. 03:55.260 --> 03:57.860 And that module is where we actually kick off. 03:57.860 --> 03:59.500 We initiate the run. 03:59.780 --> 04:03.860 And when we actually want to run it we just type create run. 04:03.980 --> 04:05.300 And that will actually do that. 04:05.300 --> 04:09.540 It will execute main I think behind the scenes it just simply does. 04:09.580 --> 04:16.300 You've run Main.py and that does bring up a good point that this whole thing, when you do this, when 04:16.300 --> 04:22.260 you when you type create, create crew, my crew, it sets up a you've project crew uses you've which 04:22.260 --> 04:25.420 which makes which is great for us since we're using UV as well. 04:25.580 --> 04:26.780 But it makes a project. 04:26.780 --> 04:32.660 So you'll also see in this micro directory you'll see some of the the UV project configuration files 04:32.660 --> 04:33.340 as well. 04:33.340 --> 04:39.220 So we're going to be having these UV projects within our bigger UV project for the whole course. 04:39.300 --> 04:41.940 And that will make more sense when you see it in action. 04:42.220 --> 04:44.820 And what better time to see it in action than right now. 04:44.860 --> 04:46.100 Let's go and give this a try.
