Cannot use my custom API key

Bug Reports
1

Describe the Bug

When trying to enter my custom API key (with the api.openai.com pattern) in the appropriate field, the system does not accept the key, even though it is valid. The “enable” button does not work after the key is entered.

Steps to Reproduce

Steps to reproduce the issue:

Access the models menu.

Click to add a custom API key.

Enter a valid key with the domain OpenRouter.

Confirm the correct endpoint.

Try to activate the key — the “enable” button doesn’t work or the key is not validated.

OK thanks

Do you have any prediction? Because the error still remains

It seems like a bug. I’ve already forwarded this to our team, and I hope we can fix it soon.

I’m having the same issue trying custom model v0. I’m using the correct v0 api key and curstom api base v0 (from v0 in Cursor)

but api key step just switches back off just like in your video.

Let’s wait and hope it resolves I’m a pro but I use the custom API for shallow work to make requests more powerful for fast requests. I’m being forced to use the fast ones now Open router gives me 1000 free days

HELLO, HOW MUCH? UNFORTUNATELY, I UPDATED THE CURSOR AND IT STILL REMAINS THE SAME

IT IS NOT POSSIBLE TO USE MY OWN API KEY. DO YOU HAVE AN OPINION ON THIS MATTER?
