Hey there.

00:00.800 --> 00:01.480
Ethan here.

00:01.880 --> 00:07.000
And up until now, we saw how to use the link chain create agent.

00:07.000 --> 00:10.560
And we saw the interface and how we can use it.

00:10.680 --> 00:16.040
We still don't really understand what all this magic and how it's working under the hood.

00:16.440 --> 00:23.560
And the goal of this section is to help us with the intuition of understanding how it's working.

00:23.560 --> 00:25.480
And what is this algorithm?

00:25.480 --> 00:28.400
What is this react algorithm which is happening under the hood?

00:28.720 --> 00:33.720
And in this section, we're going to be taking a couple of steps back in time.

00:33.920 --> 00:40.200
And we are going to review how to use the original link chain react agent.

00:40.320 --> 00:47.600
So this is the first version of the agent which was introduced by Lang Chain back a couple of years

00:47.600 --> 00:48.040
ago.

00:48.320 --> 00:51.000
And this was really what started it all.

00:51.040 --> 00:57.120
Now it's important to note that today it is not a recommended way to create agents.

00:57.120 --> 01:02.840
The recommended way is to use the Lang chain create agent function, which we already reviewed.

01:03.280 --> 01:09.280
By the way, I've been working with many customers, implementing agents, and in reality lots of companies

01:09.280 --> 01:14.860
didn't upgrade their versions and they still have those react agents in production.

01:15.660 --> 01:19.620
Now this section is super, super important.

01:19.620 --> 01:24.020
And we're going to review the OG create React agent.

01:24.140 --> 01:28.260
And we're going to see how everything originated.

01:28.300 --> 01:33.140
Now in this section we're going to be learning the interface in the section afterwards we're going to

01:33.180 --> 01:35.060
really implement it under the hood.

01:35.100 --> 01:38.980
And we're going to understand the react algorithm in depth.

01:39.220 --> 01:44.540
Now you might be thinking, why are we jumping back in time and learning about this?

01:44.780 --> 01:51.660
And trust me, if you want to get a deep understanding of AI agents, this and the next sections are

01:51.780 --> 01:52.660
a must.

01:53.060 --> 01:57.900
To learn how to use a technology is one thing, and we did it in the previous section.

01:58.140 --> 02:04.220
However, to really understand in depth how this technology is built and what was the motivation for

02:04.220 --> 02:07.740
the current implementation, what has become better over the years?

02:07.980 --> 02:10.660
How this technology evolved to what it is today?

02:11.020 --> 02:17.940
It is the deepest layer of depth you can gain in my job here is to dive deep into this because if you

02:17.940 --> 02:22.020
want, you can simply check out the docs and you would understand how to use this technology.

02:22.060 --> 02:25.060
If you want to learn more, then this is the place for you.
