func Stale(t Table, asOf time.Time, maxAge time.Duration) []string

Stale returns a sorted list of model IDs whose UpdatedOn is empty, unparseable, or older than maxAge relative to asOf.

Types ¶

type Breakdown ¶

type Breakdown struct{ Input, Output, CacheRead, CacheWrite int }

Breakdown is NORMALIZED token counts: Input EXCLUDES cached.

type Cost ¶

type Cost struct {
	Currency             string
	Input, Output, Total float64
}

type Rates ¶

type Rates struct {
	Currency       string  `json:"currency"`
	InputPerM      float64 `json:"input_per_m"`
	OutputPerM     float64 `json:"output_per_m"`
	CacheReadPerM  float64 `json:"cache_read_per_m"`
	CacheWritePerM float64 `json:"cache_write_per_m"`
	UpdatedOn      string  `json:"updated_on,omitempty"`
	Source         string  `json:"source,omitempty"`
}

type Table ¶

type Table map[string]Rates

func Default ¶

func Default() Table

Default returns embedded rates ⊕ $AWF_PRICING_FILE (whole-entry replace), loaded once.

func (Table) Derive ¶

func (t Table) Derive(model string, b Breakdown) (Cost, bool)
