live stream I will show you uh the open
0:02
AAI actually terminal coding agent it's
0:07
called as codeex and if you simply type
0:10
open AI codeex on Google the very first
0:13
uh
0:15
uh the first website comes right here
0:18
this is the official website openai.com
0:21
and this is their terminal agent codeex
0:25
so right here uh
0:28
let me just Open the zoom it tool.
0:32
So with the help of this agent, you can
0:34
use the chat GPT latest models on your
0:37
terminal
0:39
GPD5.
0:42
So this is the agent name codeex. This
0:44
is developed by this company OpenAI
0:46
which has chat GPT GPT5. So this is the
0:48
terminal agent. And now to install this
0:51
it's very simple. You execute this
0:53
command npmi-g
0:55
for installing it globally at the rate
0:58
open/codeex
1:01
and for installing this you should have
1:03
nodejs installed uh the latest version
1:05
of nodejs so I have already installed it
1:08
so I have the latest version which is
1:10
22.17.0 zero and now you can install
1:14
this by executing this command npmi-g
1:19
at the rate open ai/codex.
1:22
So this is the command here. You simply
1:24
execute this command to install this. So
1:27
this will hardly take 5 to 10 seconds to
1:29
install it. So once it is installed,
1:33
you go to the documentation. It's also
1:35
available as a extension as well in
1:37
various of these editors as well.
1:43
And it's also available on their website
1:45
as well. Uh unfortunately it's not
1:47
available for the free users. You do
1:49
need to upgrade. And this is the
1:51
screenshot where you exactly tell what
1:53
sort of application you want to develop
1:55
and it actually develops your
1:57
application. So now to try this you do
1:59
need to upgrade to their plus and the
2:02
pro plan which basically comes with all
2:05
the features that they are offering.
2:08
Unfortunately, in the free plan, it
2:10
doesn't show you. You do need to upgrade
2:12
to plus and pro plan and they also have
2:16
the extension for VS code as well. So,
2:19
you simply search for this extension
2:21
which is codeex.
2:23
This extension will come right here and
2:25
you can install this extension. This is
2:27
the extension right here.
2:29
It's basically by OpenAI. So, once is in
2:33
it is installed right here. You can
2:35
basically
2:37
login right here
2:41
and for the AI terminal right here uh
2:44
after you install this.
2:48
So now you can see it is automatically
2:50
installed. So you simply write here
2:52
codeex on the terminal and basically
2:55
after you write this it will
2:57
authenticate yourself automatically. The
2:59
window will open open AI's command line
3:03
coding agent. So as you can see right
3:05
here, this is a great alternative to
3:06
tools like clot and uh Gemini. So here
3:11
there are two types of authentication.
3:13
If you have an API key,
3:16
you can provide that or you can sign in
3:18
with the chat GPT. So you can click on
3:21
continue.
3:23
So this will authenticate the access. So
3:26
that's all that we need to do right
3:28
here. Uh after that
3:34
you again do this process once again.
3:44
So now you are successfully signed in.
3:46
So now it will show this message to you.
3:49
Welcome to Codeex.
3:55
Just wait here.
3:58
So this you all only need to do for the
4:00
very first time after you are signed in.
4:37
So here you will basically type whatever
4:40
thing that you want to do.
4:46
So now you can see you are using the
4:48
open AI codeex. So after this
4:50
authentication you can basically choose
4:52
what sort of model you want to use.
4:56
So you will simply write /mod and we
4:59
have these four models which are
5:00
available. GPT5, GPT5 low, medium, high.
5:05
So here you can select any of these
5:07
models and right here you can simply say
5:10
what is you can ask any sort of question
5:12
right here.
5:16
So yeah, so there is a restriction out
5:18
there. It's not available for the free
5:19
users. So now to use this inside your
5:22
charge GPT plan, you need to upgrade to
5:25
plus.
5:26
And once you do this
5:35
so just go to chat GPT and on their
5:38
account here you will see this section
5:40
upgrade plan and yeah so do need a
5:44
minimum of plus plan it's not available
5:46
in the go plan also you do need to
5:49
upgrade to plus plan and pro plan after
5:52
that once it it detects it will
5:55
automatically work. So these are the
5:57
option right here.
6:00
So
6:02
you also have the init command which
6:04
will generate a
6:07
documentation file for this agent to
6:09
work for generating your applications.
6:12
So these are the four commands which are
6:14
there to create a new chat. You simply
6:17
write new init compact difference
6:21
mention status. So all these commands
6:24
are there.
6:26
So definitely try this OpenAI uh
6:29
terminal agent for spec specifically
6:32
building coding applications and
6:34
debugging it.
6:40
So it's available right inside your
6:42
command line.
