How do experimental model providers work on intellij plugin?

I have intellij and I want to connect to an azure model provider.
I have edited .idea/.sourcegraph/cody_settings.json to read

{
  "cody.dev.models": [
    {
      "provider": "openai",
      "apiEndpoint": "https:/REDACTED.openai.azure.com/openai/deployments/gpt-4o/chat/completions?api-version=2024-10-21",
      "apiKey": "REDACTED",
      "model": "gpt-4o",
      "inputTokens": 32000,
      "outputTokens": 4000,
      "options": {
        "temperature": 0.0,
      },
    },
  ],
}

This seems to be all I should need to do but my model fails to load nor do I get any errors.

What am I missing?
