Struct ModelPrice 

pub struct ModelPrice {
    pub input_per_1m: f64,
    pub output_per_1m: f64,
    pub cached_per_1m: f64,
    pub reasoning_per_1m: f64,
}

One model’s price, in USD per 1,000,000 tokens (input and output billed separately, matching provider pricing). Compiled to integer micro-dollars at load (see crate::llm).

cached_per_1m prices the cached-prompt subset (prompt_tokens_details.cached_tokens, usually a steep discount) and reasoning_per_1m the reasoning subset (completion_tokens_details. reasoning_tokens). Both default to 0.0, which means inherit the base input/output rate — so an existing book prices exactly as before; set them only to apply a provider’s separate cached/reasoning rate.

Fields

input_per_1m: f64

output_per_1m: f64

cached_per_1m: f64

USD per 1M cached prompt tokens. 0.0 = inherit input_per_1m.

reasoning_per_1m: f64

USD per 1M reasoning tokens. 0.0 = inherit output_per_1m.
