# benchmark

> The Token Value Benchmark (contract 1.16): your own runs and the league table per task class — cost per successful task, quality at the bar, tokens in, out, cached and reasoning, value per unit cost, relative token value, cache effect, latency and escalation cost — with the plain sentence for each class.

The Token Value Benchmark (contract 1.16): your own runs and the league table per task class — cost per successful task, quality at the bar, tokens in, out, cached and reasoning, value per unit cost, relative token value, cache effect, latency and escalation cost — with the plain sentence for each class. Read-only: starting a run is a person’s action in LightHouse, because it spends money on models.

**Role:** viewer and above (any person, AAL staff, machine key).

**Acts:** no. It only reads; nothing an AI agent calls through MCP approves, pays, or changes a limit.
