What it is

CostLens — definition

CostLens is a cost-observability tool for AI agents and LLM workflows that attributes spend per run, per tool, and per model, so teams can find the workflows burning the most token budget.

What this is NOT

  • Not a law firm, GRC platform, or ISO certification body.
  • Not a guarantee that drafted policies will satisfy every regulator or auditor.
  • Not a payment processor, cloud bill, or cost guarantee.

Controller / Processor — When packs mention privacy roles, we use GDPR Art.4 labels: Controller and Processor (decision-support only).
