WEBVTT 00:00.160 --> 00:01.800 Well, this might be a bit of an anti-climax. 00:01.840 --> 00:04.440 I'm just saying we have to write our crew function. 00:04.440 --> 00:07.400 We don't have to write our crew function because the default thing, there is all that we need. 00:07.400 --> 00:08.800 We don't need to do anything else. 00:08.800 --> 00:12.840 We've already got something which can do exactly what we want. 00:13.120 --> 00:17.000 What we do need to do still is come into main and rewrite this. 00:17.040 --> 00:19.440 And of course it's got all of the usual stuff. 00:19.440 --> 00:21.080 We don't need any of the stuff that's there. 00:21.120 --> 00:27.320 We'll just delete everything and come back here and write our own run function. 00:27.360 --> 00:28.680 Def run. 00:29.040 --> 00:30.920 This is the thing that's going to run the crew. 00:31.240 --> 00:37.320 And so we are going to say inputs equals assignment. 00:37.360 --> 00:38.640 How do I spell assignment. 00:38.680 --> 00:40.240 Assignment. 00:40.240 --> 00:42.040 There we go colon. 00:42.040 --> 00:44.880 Let's just give that a variable assignment for now. 00:45.240 --> 00:56.920 And then we're going to say results equals coder dot crew dot kickoff passing in those inputs. 00:57.200 --> 01:07.050 And then we want to print result Raw is how the result will come back and then we will indeed have. 01:07.290 --> 01:11.330 We don't need that main in there because it will automatically run that for us. 01:11.730 --> 01:12.210 Okay. 01:12.250 --> 01:15.730 And so what's left to do, of course, is to set the actual assignment. 01:15.850 --> 01:19.250 So let's come up with assignment assignment. 01:19.250 --> 01:25.570 And we're going to do something challenging here because I want to check if I said something like the 01:25.610 --> 01:27.370 default the cursor has got for us there. 01:27.410 --> 01:27.650 Right. 01:27.690 --> 01:30.170 A Python script that prints Hello world. 01:30.370 --> 01:36.690 Then we might not know for sure that it's actually running it, because Llms are perfectly capable of 01:36.690 --> 01:40.690 knowing what a script like that would yield would result in. 01:40.690 --> 01:44.650 So it could generate the Python code and then pretend it ran it. 01:44.650 --> 01:48.050 So we want something that it can't do any pretending for. 01:48.090 --> 01:53.130 And so I have one thing to show you, although knowing Llms, it probably could pretend this as well, 01:53.130 --> 01:54.850 but I certainly think this is a harder one. 01:55.210 --> 02:03.510 So I wanted to write a Python program to calculate the first 10,000 terms of this series, multiplying 02:03.510 --> 02:04.830 the total by four. 02:05.230 --> 02:07.030 So I put it in quite a complicated way. 02:07.350 --> 02:15.910 And here's the series one minus a third plus a fifth, minus a seventh plus dot dot dot. 02:16.550 --> 02:24.270 And so I'm just kind of it's a classic case of just sort of asking the LM to figure it out like a reasonable, 02:24.270 --> 02:26.310 intelligent human would. 02:26.470 --> 02:30.390 And who would have thought a few years ago that you could write software that would be able to take 02:30.390 --> 02:35.510 something like this with all of the nuance, all of the implications, and figure out that it needs 02:35.510 --> 02:42.070 to write code to put this into a loop, to keep it going for 10,000 terms, and then to take the total 02:42.070 --> 02:43.470 and multiply it by four. 02:43.950 --> 02:53.190 And the mathmos around will probably have already spotted this as being a very slow and very, uh, 02:53.190 --> 02:55.790 boring way to calculate pi. 02:56.150 --> 03:01.550 So if it does this right, and if it calculates the first 10,000 terms and multiplies by four, then 03:01.550 --> 03:02.960 it will be an approximation. 03:03.000 --> 03:05.120 A bad approximation of pi. 03:05.480 --> 03:11.440 And now the Llms are perfectly capable of recognizing this formula and knowing that the answer should 03:11.440 --> 03:12.120 be pi. 03:12.160 --> 03:17.680 But what's much harder is for them to realize that 10,000 terms would be approximately pi, and be wrong 03:17.720 --> 03:19.000 after a few decimal places. 03:19.040 --> 03:23.000 And so that's how we can tell that it's really doing its thing. 03:23.280 --> 03:25.440 So I hope that all makes sense. 03:25.440 --> 03:27.160 It's time for us to actually run this. 03:27.600 --> 03:29.400 All right, everyone, this is exciting. 03:29.440 --> 03:30.240 The drum roll. 03:30.240 --> 03:33.680 We're going to try and have our coder do its thing. 03:33.680 --> 03:35.280 So let's bring up a terminal. 03:35.640 --> 03:37.680 Let's go into the third directory. 03:37.680 --> 03:42.360 Let's go into coder and let's type crew I run to kick this off. 03:42.480 --> 03:46.920 And remember the challenge is now being set to our agent. 03:46.960 --> 03:48.320 You can see it started. 03:48.360 --> 03:51.920 There's the command and it's now going to be thinking about it. 03:52.160 --> 03:56.040 And something just ran and failed in the code interpreter. 03:56.040 --> 04:00.480 So it's that one means it's its first try and it's trying again. 04:00.880 --> 04:02.640 So it's not like it always works. 04:02.730 --> 04:07.050 At least it shows us that something is trying to run in an interpreter. 04:07.090 --> 04:07.410 Okay. 04:07.450 --> 04:08.290 It's done some code. 04:08.290 --> 04:09.010 It's got an answer. 04:09.050 --> 04:10.570 It just all happened really fast. 04:10.850 --> 04:15.970 So, um, this is the code that it's got, that it's written, and this is the output. 04:15.970 --> 04:21.690 It's used an interesting technique I can see it's it's obviously, uh, it's, it's going through the 04:21.690 --> 04:23.370 number of terms as it should do. 04:23.770 --> 04:26.250 It's a number of terms it sets down below. 04:26.250 --> 04:27.330 That's nicely done. 04:27.570 --> 04:33.210 And then it's using this idea of take minus one to the power of the index, which is either going to 04:33.210 --> 04:34.690 be minus one or plus one. 04:34.730 --> 04:36.010 It's a clever trick. 04:36.330 --> 04:39.410 And dividing by that which looks right to me. 04:39.450 --> 04:43.490 And then where do we see it multiplying the result by four. 04:44.370 --> 04:45.050 There, right there. 04:45.090 --> 04:47.290 I was going to say that would be suspicious. 04:47.330 --> 04:50.210 It does indeed multiply the result by four. 04:50.330 --> 04:58.250 And that's why we get 3.14149, not 3.14159, because it is just an approximation of pi. 04:58.450 --> 05:00.330 And it seems to have worked. 05:00.330 --> 05:04.230 And indeed, if also we see that it's created an output file. 05:04.270 --> 05:05.190 Yes it has. 05:05.390 --> 05:11.110 And here in the output file we will find the same output which has got the code. 05:11.230 --> 05:13.190 The output below it. 05:13.430 --> 05:18.310 And I gotta tell you, I'm blown away by how easy it is to do this. 05:18.470 --> 05:24.150 And all of the machinery that's happening behind behind the scenes to be able to start a Docker container, 05:24.190 --> 05:29.110 come up with the code, run the code, come up with the answer to the way that I expressed it. 05:29.110 --> 05:30.630 In quite a simplistic way. 05:30.750 --> 05:32.710 It just figured the whole thing out. 05:32.830 --> 05:35.350 And I think that's that's really cool. 05:35.870 --> 05:36.790 And there you have it. 05:36.830 --> 05:39.310 We just gave coding skills to an agent. 05:39.350 --> 05:42.630 We have our coder agent and it was so simple. 05:42.630 --> 05:44.910 And I hope you enjoyed it as much as I did. 05:45.110 --> 05:45.670 All right. 05:45.670 --> 05:47.470 Well, it ain't over yet. 05:47.470 --> 05:53.110 We've got more to go because the natural extension, now that we've got a coder, we can build an entire 05:53.110 --> 05:54.590 engineering team. 05:54.630 --> 05:56.830 It's really the goes to the meaning of crew. 05:56.870 --> 06:01.590 We're going to build a crew, an engineering crew, to be able to solve problems front to back. 06:01.590 --> 06:03.350 And it's going to be so great. 06:03.390 --> 06:04.190 I'll see you then.
