[BUG] "Connection Failed" when adding OpenAI provider that has a $0 balance

[pbarney]

Bug Description
When setting up the OpenAI provider, after pasting in the API key and pressing the Check button, the Chatbox will display a Connection Failed message if the account balance is zero ($0.00). This may be the case with other providers, but I have not tested this.

Steps to Reproduce

1. Have a $0.00 balance in your OpenAI API account
2. Go to Settings → Model Provider → OpenAI → Enter your API key → press Check
3. See the Connection Failed error

Expected Results
I would expect a more helpful message such as Insufficient Quota. OpenAI returns an HTTP 429 error with an insufficient_quota message:

{
  "error": {
    "message": "You exceeded your current quota, please check your plan and billing details.",
    "type": "insufficient_quota",
    "param": null,
    "code": "insufficient_quota"
  }
}

Desktop:

• Operating System: Windows
• Application Version: 1.13.1
