Calculates LLM costs from token counts and model pricing data.

Summary

Functions

calculate(arg1, model_id, input_tokens, output_tokens)

Calculate cost in USD from token counts and model pricing.

lookup_pricing(model_id)

Look up pricing for a model. Returns {input_rate, output_rate} or nil.

lookup_pricing_table()

Returns the hardcoded fallback pricing table as a map of %{model_id => {input_rate, output_rate}}.

Functions

calculate(arg1, model_id, input_tokens, output_tokens)

@spec calculate(
  String.t() | nil,
  String.t() | nil,
  non_neg_integer(),
  non_neg_integer()
) :: float()

Calculate cost in USD from token counts and model pricing.

Returns 0.0 if pricing cannot be determined.

lookup_pricing(model_id)

@spec lookup_pricing(String.t() | nil) :: {float(), float()} | nil

Look up pricing for a model. Returns {input_rate, output_rate} or nil.

lookup_pricing_table()

@spec lookup_pricing_table() :: %{required(String.t()) => {float(), float()}}

Returns the hardcoded fallback pricing table as a map of %{model_id => {input_rate, output_rate}}.
