Struct SetModelOptions 

pub struct SetModelOptions {
    pub reasoning_effort: Option<String>,
    pub reasoning_summary: Option<ReasoningSummary>,
    pub context_tier: Option<ContextTier>,
    pub model_capabilities: Option<ModelCapabilitiesOverride>,
    pub auto_tier: Option<AutoTierPreference>,
}

Options for Session::set_model.

Pass None to set_model to switch model without any overrides.

Fields

reasoning_effort: Option<String>

Reasoning effort for the new model (e.g. "low", "medium", "high", "xhigh", "max").

reasoning_summary: Option<ReasoningSummary>

Reasoning summary mode for the new model. Use ReasoningSummary::None to suppress summary output regardless of whether reasoning is enabled.

context_tier: Option<ContextTier>

Explicit context window tier for the new model. Leave unset to use normal model behavior with no explicit tier.

model_capabilities: Option<ModelCapabilitiesOverride>

Override individual model capabilities resolved by the runtime. Only fields set on the override are applied; the rest fall back to the runtime-resolved values for the model.

auto_tier: Option<AutoTierPreference>

Auto routing preference to stage atomically with selecting the auto model.

Leave as None to leave the current preference alone. The runtime rejects this option when the model is anything other than auto; use Session::set_auto_tier to change the preference without changing the selected model.
