Struct Model 

pub struct Model {
    pub billing: Option<ModelBilling>,
    pub capabilities: ModelCapabilities,
    pub default_reasoning_effort: Option<String>,
    pub id: String,
    pub model_picker_category: Option<ModelPickerCategory>,
    pub model_picker_price_category: Option<ModelPickerPriceCategory>,
    pub name: String,
    pub policy: Option<ModelPolicy>,
    pub supported_context_tiers: Option<Vec<String>>,
    pub supported_reasoning_efforts: Option<Vec<String>>,
}

Copilot model metadata, including identifier, display name, capabilities, policy, billing, reasoning efforts, and picker categories.

Experimental. This type is part of an experimental wire-protocol surface and may change or be removed in future SDK or CLI releases.

Fields

billing: Option<ModelBilling>

Billing information

capabilities: ModelCapabilities

Model capabilities and limits

default_reasoning_effort: Option<String>

Default reasoning effort level (only present if model supports reasoning effort)

id: String

Model identifier (e.g., “claude-sonnet-4.5”)

model_picker_category: Option<ModelPickerCategory>

Model capability category for grouping in the model picker

model_picker_price_category: Option<ModelPickerPriceCategory>

Relative cost tier for token-based billing users

name: String

Display name

policy: Option<ModelPolicy>

Policy state (if applicable)

supported_context_tiers: Option<Vec<String>>

Context-window tiers this model offers, when the provider advertises them independently of tiered token pricing. Copilot models carry their tiers in billing.tokenPrices; a provider that has no pricing to publish (an agent host reached over AHP, for example) declares them here instead, so the model picker can still offer the tier toggle.

supported_reasoning_efforts: Option<Vec<String>>

Supported reasoning effort levels (only present if model supports reasoning effort)
