Documentation

Overview

Package cost estimates per-model pricing for prompt tokens.

Prices are per 1M input tokens, in USD, approximate list prices as of this project's v1. The map is used for README-style "cost impact per 100k runs" projections; it is not a substitute for live billing data.

Functions

func EstimateBulk 

func EstimateBulk(model string, count, invocations int64) float64

EstimateBulk computes the cost to run each model's tokens n times.

func Lookup 

func Lookup(model string) float64

Lookup returns the USD per-1M-token price for a model. Unlisted models fall back to a neutral default so projections never crash.

func SetOverride added in v1.3.0 

func SetOverride(model string, per1M float64)

SetOverride pins model's price, overriding the built-in list.
