Uh hello guys, welcome to this live
0:02
stream. So in this live stream, I'll
0:03
show you how to get a Gemini 2.5 claude
0:07
4 API key for completely free and there
0:11
are two websites which are offering this
0:13
functionality. The first one is uh if
0:16
you go to the browser simply type this
0:18
address a4f.co.
0:21
So this is the address. I've also given
0:23
the link in the description of this live
0:25
stream. So this is a single unified
0:28
place where you can access any a AI
0:31
provider
0:33
from a single subscription. So you don't
0:35
need multiple subscriptions. So in this
0:37
website if you go to the model section
0:40
you can access a wide range of AI models
0:43
in a single platform. And right here you
0:45
can search for your favorite AI model.
0:47
So it has all the AI models free and
0:50
paid as well. You can basically filter
0:53
out the free models which are there by
0:55
simply clicking on this and uh these are
0:59
all models which are free. You can even
1:01
filter out by company as well DC Google.
1:04
So all these AI models are there. Simply
1:07
click on individual model and it
1:10
basically provides you with the name of
1:12
the model everything and this option
1:14
lets you try the model completely free.
1:17
You click on tribe and right it has a
1:20
playground section. So simply create
1:23
account here if you are new to the
1:25
website.
1:27
So currently it is in beta phase.
1:31
And the second website is most popular
1:33
which is open router.ai. So this is
1:36
similar to this website. It has a
1:39
unified
1:40
interface for accessing different AI
1:43
providers. You can check out the model
1:45
section. Currently it has almost 530
1:48
models and it also has free models as
1:52
well. So you can filter out in the left
1:54
section.
1:56
So all these models it's completely
1:58
free. You can click on individual model
2:01
and it has a chat button as well. You
2:03
can click on this and you can try the
2:06
model directly by typing a message and
2:08
the model will respond. And once you
2:11
loging in with your Google account
2:14
right here in the profile picture, go to
2:16
the key section to create an API key.
2:19
So once you click this,
2:23
you click this button create API key.
2:25
And this will let you just give it a
2:28
name and click on create API key. So in
2:31
this easy way you can create an API key
2:33
for any AI provider such as Gemini,
2:36
Claude, Deep Sea, Croc anything.
2:42
And this is
2:45
this next website.
2:48
These are the two websites which
2:50
provides you with API keys. So once you
2:52
log in using this again you go to the
2:56
profile picture go to API keys right
2:59
here itself the process is simple you
3:02
click on create API key just give it a
3:04
name and click generate API key. So now
3:06
it will generate that API key and
3:09
through this API key you can access any
3:11
model. So simply copy to clipboard
3:15
and uh
3:18
you can even access inside the
3:20
playground section. Simply paste this
3:22
API key and once you paste it this chat
3:25
interface will open and right here from
3:27
the drop-down you can access any model
3:29

3:34
are free models and the pro models are
3:36
also there. You can see that you can

3:47
and you can access it for completely
3:49

3:59

can simply select the free models right
4:09
here. Simply

so once you you can see the speed of
4:23
generating the response. So once you get
4:25
the API key, you can even use it inside
4:27
VS code. Simply install any extension.
4:31
One such extension is clin and you
4:34

4:36
API key. So these are two free ways by
4:40
which you can get API keys of any AI
4:42
provider. First one website is open
