Overview

Package pricing prices token usage deterministically. It is the basis of the dollar budget the governor enforces and the cost ledger records. Prices are static, defensible list prices (USD per 1M tokens) and are overridable via config — RiskKernel never asks an LLM what something costs.

Types

type Rate 

type Rate struct {
	InputPerM  float64
	OutputPerM float64
}

Rate is a model's price in USD per 1,000,000 tokens.

type Table 

type Table struct {
	// contains filtered or unexported fields
}

Table prices models. The zero value is usable (built-in rates only); use NewTable to layer config overrides on top.

func NewTable 

func NewTable(overrides map[string]Rate) *Table

NewTable returns a Table seeded with the built-in rates, with overrides applied on top (override keys are matched by the same prefix rule).

func (*Table) Cost 

func (t *Table) Cost(model string, promptTokens, completionTokens int64) (usd float64, ok bool)

Cost returns the USD cost of the given token counts for a model, and whether the model was priced. When ok is false the cost is 0 — the caller decides whether to treat an unpriced model as a dollar-budget enforcement gap.

func (*Table) Rate 

func (t *Table) Rate(model string) (Rate, bool)

Rate returns the rate for a model and whether it was found. Matching is by longest case-insensitive prefix so dated snapshots resolve to their family.
