fix: OpenAI API key support

[LordBounty]

Description
There is no response after copying the API key at the input API window.

I tried doing this:
It seems that I will only enter the main page after entering: "sk-" + the specified number of characters in the input API key window.
However when I get a new API key from "get a key" link, the key was too long to be recognized that I was stuck in the input window.

It's a nice tool! If it's convenient, can check it? let's see what the problem is.

Many thanks.

I'm not sure if this is ok to share on this project. But I built a project called spaice that is a more user friendly version of this with a lot more features. Its free to use and no signup
