Struct ModelConfig 

pub struct ModelConfig {
    pub family: String,
    pub model: String,
    pub api_base: String,
    pub api_key: String,
    pub labels: Vec<String>,
    pub context_window: usize,
    pub max_output: usize,
    pub effort: Option<ModelEffort>,
    pub disabled: bool,
    pub bearer_auth: bool,
    pub stream: bool,
}

Serializable configuration for constructing a model adapter.

Debug is implemented manually so the api_key is redacted and never leaks through {:?} logging.

Fields

family: String

Provider family, such as gemini, anthropic, openai-response or openai.

model: String

Provider-specific model name.

api_base: String

Base URL for the provider API.

api_key: String

API key used by the provider adapter.

labels: Vec<String>

Optional labels for selecting this model in the engine.

If omitted, the provider model name is used as the only label. Common labels include primary, pro, flash, lite, audio, video, image, memory.

context_window: usize

Provider context window in input tokens; 0 means unknown.

max_output: usize

Provider maximum output tokens; 0 means unknown.

When known, it caps each request’s explicit output budget (see Model::completion) and replaces the default budget of adapters that always send one (Anthropic max_tokens, Gemini maxOutputTokens).

effort: Option<ModelEffort>

Optional reasoning/thinking effort for providers and models that support it.

Supported config values are minimal, low, medium, high, and max. The effective set depends on the selected provider and model.

disabled: bool

Skips this model when loading a list of configs.

bearer_auth: bool

Sends Anthropic credentials with bearer authentication instead of the provider-specific API-key header.

stream: bool

Whether to request streaming completions from this model. The OpenAI Responses adapter always streams and aggregates the result, regardless of this setting.
