Retry churn turns one user action into multiple paid model calls because of timeouts, malformed outputs, rate-limit recovery, tool errors, or agent loops.
What to check first
Retry churn turns one user action into multiple paid model calls because of timeouts, malformed outputs, rate-limit recovery, tool errors, or agent loops.
Measure paid attempts per successful user action.
Break out failed-call cost from successful request cost.
Fix unstable prompts, parsers, tools, and timeout policies before scaling traffic.
