Struct ModelInfo 

pub struct ModelInfo {
    pub context_length: Option<u32>,
    pub pricing: Option<PricingConfig>,
    pub vision: Option<bool>,
}

Per-model metadata: context window and token pricing.

Every field is Option so partial overrides work — a config entry that sets only context_length can leave pricing unset.

Fields

context_length: Option<u32>

Maximum context window in tokens.

pricing: Option<PricingConfig>

Token pricing (per-axis costs per million tokens).

vision: Option<bool>

Whether the model accepts image/video input.

Implementations

impl ModelInfo

pub fn cost(&self, u: &Usage) -> f64

Compute cost in USD for the given usage. Returns 0.0 when pricing is unset.

Each axis is priced independently. Secondary rates fall back to the next-coarser bucket when unset:

• cache_read, cache_write, audio_input → input_cost_per_million
• reasoning, audio_output → output_cost_per_million

None never means “free” — that would silently zero out billing on any axis where pricing data is incomplete.
