opencode Can users customize the relay API server and model?

Question

Why hasn't this important feature been developed yet? There are many casual users who need custom API interface services!

I've checked, and the problem remains unresolved! I especially want to mention that I suggest adding this feature to the desktop version; I know many people are using the API relay service! Please add a provider compatible with OpenAI!!! The user script configuration is too cumbersome!

The key is to specify baseURL in options and models. You can always follow instruction on https://opencode.ai/docs/providers/#custom-provider and do this

{
  "$schema": "https://opencode.ai/config.json",
  "provider": {
    "myprovider": {
      "npm": "@ai-sdk/openai-compatible",
      "name": "My AI ProviderDisplay Name",
      "options": {
        "baseURL": "https://api.myprovider.com/v1"
      },
      "models": {
        "my-model-name": {
          "name": "My Model Display Name"
        }
      }
    }
  }
}

Completely agree. You only need to change the baseURL for the appropriate provider - I am using this for Anthropic over Azure on daily basis. Works like a charm.
