Struct ProviderOverrideConfig 

pub struct ProviderOverrideConfig {
    pub models: Vec<String>,
    pub base_url: Option<String>,
    pub api_key_env: Option<String>,
}

Configuration for overriding a built-in provider’s model list.

Allows users to extend built-in providers (e.g., opencode-zen, opencode-go) with additional custom models, and optionally override the provider’s base URL or API key environment variable.

Example

[providers.opencode-zen]
models = [
    "opencode/gpt-5.4",
    "opencode/gpt-5.4-mini",
    "my-custom-model",
]
base_url = "https://custom-endpoint.example.com"
api_key_env = "MY_CUSTOM_KEY"

Fields

models: Vec<String>

Additional model identifiers to offer for this built-in provider.

These models are appended to the provider’s hardcoded model list and appear in the /model picker alongside built-in entries.

base_url: Option<String>

Optional base URL override for the provider endpoint.

When set, custom models from this override are routed to the specified endpoint instead of the provider’s default. Values from repository-controlled workspace/project layers are rejected.

api_key_env: Option<String>

Optional environment variable name for the API key.

When set, overrides the provider’s default API key environment variable for models from this override. Values from repository-controlled workspace/project layers are rejected.
