description: >-
  FinOps view of OpenMeter. OpenMeter is itself a FinOps-enabling tool - it
  meters product/API usage and turns it into entitlements and invoices - so
  this artifact covers both the cost of running OpenMeter and the usage meters
  OpenMeter produces for your own products. OpenMeter Cloud is billed on metered
  event volume; the open-source deployment carries only self-hosted
  infrastructure cost (ingestion, ClickHouse, Kafka/streaming).
notes: >-
  Cloud tier prices and included event allowances are subject to change; verify
  against the OpenMeter pricing page during reconciliation. The meters listed
  below are representative of what OpenMeter itself emits and of what you would
  typically define for an AI/API product.
