Uh, hello guys. In this video, I will
0:02
actually show you a free way by which
0:05
you can get this uh
0:07
Deepseek API key through OpenRouter and
0:10
create unlimited applications inside VS
0:12
Code. So, for this you require an
0:14
extension which is called as RooCode. I
0:17
am just sharing this secret way by which
0:20
So, you need this extension RooCode. I
0:22
have already installed it. So, directly
0:24
install this and activate this
0:25
extension. So, once you activate this
0:27
extension,
0:29
the extension will show right here. So,
0:32
simply activate this.
0:34
So, once you are using it for the very
0:36
first time, you need to go to the
0:37
settings of this. And from there, you
0:40
select the API provider.
0:42
And for this, we will be using
0:44
OpenRouter. OpenRouter is a very special
0:47
website which contains all the AI models
0:49
in a single place.
0:51
And you just need to create a free
0:53
account right here. I've already created
0:55
a free account. I've logged in directly
0:57
with my Google account. So, once you
0:59
sign up,
1:00
you simply create the API key. You go to
1:03
the API key section. Click click on new
1:06
key. Uh, simply copy paste your own API
1:09
key. So, I've already done that.
1:12
You just simply paste your API key from
1:14
here.
1:15
After that, inside the model, you
1:18
specifically select the free models. So,
1:21
inside, we will use the Deepseek free
1:24
model.
1:27
So, we are using this free model of
1:29
Deepseek right here. So, we selected
1:30
this Deepseek API from here,
1:34
the free model,
1:35
and click on save. After you do that,
1:38
now you simply ask any sort of question
1:40
right here in the chat box.
1:43
So, now the API will definitely work. It
1:45
will make this API request and
1:48
I'm using this
1:50
free API
1:51
through OpenRouter inside uh RooCode to
1:54
build out uh unlimited applications.
1:58
So, if you're using it for the very
2:00
first time, then it will just take some
2:02
time to configure.
2:05
And then it will respond to you. You can
2:07
see that now it is responding
2:08
successfully.
2:10
So, right here you can actually ask any
2:12
sort of question to it. You can
2:17
So, it's completely free because it's a
2:19
free model that we configured.
2:22
So, OpenRouter does contains all these
2:24
free models free.
2:25
So, if you simply search for it,
2:30
so these are all the free models that
2:31
you see
2:33
from different AI companies. They do
2:36
provide their free models directly in
2:37
OpenRouter. So, this is a secret way by
2:40
which you can do that.
2:41
And
2:43
now let's suppose I simply want to
2:45
create an application, so I will simply
2:47
say build image to PDF web app in
2:49
browser.
2:50
And create
2:53
the index.html file in
3:00
directory. Create that.
3:03
And write
3:05
all the code.
3:07
So, you simply write the prompt here,
3:09
and after that now the API will actually
3:12
create this application for you.
3:15
First of all, it will create that
3:16
directory, then it will create that
3:18
actual application for you. So, you
3:21
simply grant the permission right here.
3:22
Click on run.
3:25
So, it will create that directory for
3:26
you.
3:30
Automatically, it can create
3:32
directories, create files for you
3:34
automatically. So, in this easy way you
3:37
can
3:38
on autopilot create auto unlimited
3:41
applications using this technique that I
3:43
shared with you.
3:45
So, you just require a free account on
3:47
this website openrouter.ai.
3:49
Definitely visit this website and create
3:51
a free account, and then use this Deep
3:53
Seek API to create
4:02
So, you can see that the directory was
4:04
created.
4:07
So,
4:31
you can ask any sort of question here.
4:33
Let's suppose top
4:35
Node.js frameworks in 2026.
4:39
So, you can ask any kind of question.
4:41
So, this will not give you any warning
4:43
right here. Automatically, this will
4:47
give you the response back.
4:50
So, you just need to wait for the
4:53
model to completely respond. So, it will
4:55
take some time because it's a free
4:57
model. So, automatically, it gives you
4:59
the response back as well. So,
5:02
the top 10 Node.js frameworks as you
5:05
can see.
5:26
So, you can ask any kind of question
5:28
right here.
5:31
So, the extension is Row Code. You first
5:33
of all install this, then create account
5:35
on OpenAI router, and create an API key
5:38
directly. Configure that API key, and
5:40
use this free model of Deep Seek. So, in
5:43
this easy way, this is the secret
5:45
formula of using this approach and
5:48
creating applications.
5:50
So,
5:54
>> [clears throat]
6:03
>> So, [snorts] you can just see here it is
6:05
thinking about this. So, it's exactly
6:07
tells you what it is thinking about.
6:26
So, [snorts] this is a thing. Definitely
6:29
create this we using this secret
6:31
approach. If you like the video, please
