Struct ModelCosts 

pub struct ModelCosts {
    pub version: u16,
    pub models: HashMap<Pattern, ModelCostV2>,
}

A mapping of AI model types (like GPT-4) to their respective costs.

This struct uses a dictionary-based cost structure with exact model ID keys and granular token pricing.

Example JSON:

{
  "version": 2,
  "models": {
    "gpt-4": {
      "inputPerToken": 0.03,
      "outputPerToken": 0.06,
      "outputReasoningPerToken": 0.12,
      "inputCachedPerToken": 0.015
    }
  }
}

Fields

version: u16

The version of the model cost struct

models: HashMap<Pattern, ModelCostV2>

The mappings of model ID => cost as a dictionary

Implementations

impl ModelCosts

pub fn is_empty(&self) -> bool

true if the model costs are empty and the version is supported.

pub fn is_enabled(&self) -> bool

false if measurement and metrics extraction should be skipped.

pub fn cost_per_token(&self, model_id: &str) -> Option<&ModelCostV2>

Gets the cost per token, if defined for the given model.
