LLM engine configuration.

Fields

default_model: String

Default model in “provider/model” format. Empty string means no model configured — onboarding required.

api_key: Option<String>

Explicit API key override (highest priority). If empty/None, falls back to oxi auth store, then env vars. Masked when serialized to API responses.

provider_options: Option<ProviderOptions>

Per-provider options for fine-grained control (thinking mode, etc.). Passed through to AgentLoopConfig::provider_options.

routing_enabled: bool

Enable complexity-based model routing. When enabled, the engine can route simple tasks to cheaper models and complex tasks to more capable ones.

prefer_cost_efficient: bool

Prefer cost-efficient models when routing.

fallback_models: Vec<String>

Fallback models to try when the primary model fails.

excluded_models: Vec<String>

Models excluded from automatic routing.

role_routing: RoleRoutingConfig

Role-based model routing (RFC-032). Maps role names (e.g. “coder”, “writer”) to model IDs. When present, messages with a matching role will use the mapped model.

quick_ask_model: Option<String>

Default model for one-shot (QuickAsk) requests in “provider/model” format. When None, one-shot falls back to default_model. Lets the user point throwaway questions at a cheaper/faster model.
