I have a custom LLM configuration that I'd like to configure using only an API key & not the optional OAuth2 configuration. It seems like it is currently bugged in that `authenticationPlan` object is required when saving and I'm unable to move forward with updating my implementation.

<@253448380313763840>
I'm sorry to hear that you're experiencing issues with configuring your custom LLM. It sounds like there might be a bug with the `authenticationPlan` requirement. To assist you better, could you please provide me with the specific error message you're receiving, or any additional details about the steps you're taking that lead to the issue? This will help me understand the problem more clearly and guide you towards a solution.

You can continue this conversation by mentioning me in the message.

`Error in Saving Credentials - "authenticationPlan" must be an object` in the UI

Got it. Tagging <@&1231325148079194222> for additional help.

<@865531204849500190> if this is a bug, it's quite critical, thought you might want to be pinged directly given recency of feature - I've sniffed the API call and can replicate it via the direct API call too

<@253448380313763840> can you share the associated call id?

There's no associated call ID? I'm just trying to configure the custom LLM...

<@253448380313763840> apology for the overlook, reporting to the team.

<@253448380313763840> A issue has been created for it https://linear.app/vapi/issue/VAP-1841/customllm-api-key-bug

<@865531204849500190> Is there any update on this, when will we be able to use custom LLMs without authentication?

<@742302893385842739> Sorry for the late response. You cannot use Custom LLM without authentication because authentication is required for API requests from almost every provider.

<@865531204849500190> But for Open AI, they provide only the API key, no other authentication

I meant without OAuth, that is now mandatory, even if it says optional

Yes you can use API key we have both methods available API key and OAuth2.

No you can use either, you can give it a try now.
