1
00:00:05,590 --> 00:00:14,530
In this lesson, we are going to talk about the main challenges on each phase in the full cycle of developing

2
00:00:14,530 --> 00:00:20,530
professional LLM applications and the lessons learned about them.

3
00:00:22,520 --> 00:00:29,780
We are going to see these challenges in detail in the next practical lesson.

4
00:00:30,140 --> 00:00:34,820
But now let's talk about them quickly.

5
00:00:34,820 --> 00:00:37,190
So in the prototyping.

6
00:00:38,050 --> 00:00:51,820
Face of the cycle we are well launching told us that LM app Development teams are finding these four

7
00:00:51,820 --> 00:00:53,920
main challenges.

8
00:00:54,560 --> 00:01:02,420
How to identify what fails, how to iterate an experiment, how to make comparisons between different

9
00:01:02,420 --> 00:01:05,990
versions, and how to evaluate a prototype.

10
00:01:06,830 --> 00:01:12,470
We will talk about this in detail later in the beta testing stage.

11
00:01:12,920 --> 00:01:22,160
The chain is telling us that they observe that LM app development teams are facing one main challenge

12
00:01:22,160 --> 00:01:26,630
how to process and analyze the user feedback.

13
00:01:26,630 --> 00:01:35,870
And finally, in the production phase, Land Chain team are telling us that the developers of LM Applications

14
00:01:35,870 --> 00:01:45,200
professional LM applications are finding mostly two big challenges regarding performance and improvement.

15
00:01:45,200 --> 00:01:47,510
We will talk about them later.

16
00:01:47,510 --> 00:01:55,160
So these are the four challenges we are going to be focusing on in the prototyping phase.

17
00:01:55,160 --> 00:02:02,780
How to identify what is failing, how to iterate and experiment, how to compare the performance and

18
00:02:02,780 --> 00:02:04,940
how to test the performance.

19
00:02:05,360 --> 00:02:07,850
We will see this in detail.

20
00:02:07,850 --> 00:02:09,740
We will see the challenge.

21
00:02:09,740 --> 00:02:14,060
We will see how to solve this challenge using Lang Smith.

22
00:02:14,060 --> 00:02:22,730
And then we will see Lang Chain uh, at work solving it in a real application for the beta testing phase.

23
00:02:23,240 --> 00:02:31,460
We are going to see this challenge how to process and analyze the feedback of the initial users.

24
00:02:31,460 --> 00:02:32,990
We will see the challenge.

25
00:02:33,140 --> 00:02:41,390
We will see how Lang Smith solves it and how Lang Smith at work, uh, does it.

26
00:02:41,660 --> 00:02:49,130
And in the production phase, we are going to see these three main challenges how to keep processing

27
00:02:49,130 --> 00:02:56,720
and analyzing the user feedback, how to measure the performance of the application and how to keep

28
00:02:56,720 --> 00:02:58,670
improving the app.

29
00:02:58,670 --> 00:03:03,500
So we are going to see these challenges in detail.

30
00:03:03,500 --> 00:03:12,830
Uh, we are going to go to the practical lesson in order to see a deeper explanation of these challenges.

31
00:03:12,830 --> 00:03:17,690
And it will be I'm telling you, it will be super interesting for you.

32
00:03:17,960 --> 00:03:27,950
And once we finish the description of the challenges, we will go to see how Lang Smith solves the challenges

33
00:03:27,950 --> 00:03:31,880
in the in each of the, uh, phases.

34
00:03:31,880 --> 00:03:32,210
Okay.

35
00:03:32,210 --> 00:03:36,710
So we will go to the prototyping, then the beta testing and then the production phase.
