Metering, cost and limits

Quotas and budgets

Cap tokens, spend or requests per person, team or service, with warnings before anyone hits the limit.

What it is

Cap input tokens, output tokens, spend or request count per person, team or service token, optionally per model. Windows are daily, weekly, monthly, or rolling 24 hours, 7 days or 30 days.

Why you want it

A runaway script or a curious intern should hit a limit long before the invoice does.

The Data science team has a $1,500 monthly budget. A warning goes out at 80 percent and again at 95 percent. At 100 percent new requests are refused with a message saying when the budget resets, while the request already in flight is allowed to finish.

How it works

  • Warnings at configurable thresholds (default 80% and 95%) plus a breach alert
  • Breach behavior: let the in-flight request finish or cut it mid-stream
  • Refusals say when the limit resets
  • Team leads can manage their own team's quotas when an admin delegates it
