What it is#

Latency guardrails are budgets on how long the model may take to respond — service-level objectives (SLOs) that trigger an alert when serving gets too slow. They protect the user experience and any latency SLAs.

Tail, not average#

They track tail percentiles — p50, p95, p99 — not just the mean, because a few very slow requests ruin the experience even when the average looks fine. A typical rule fires when the current p99 exceeds, say, 1.5× a rolling baseline.

Setting the budget#

Acceptable latency is set by the use case — on the order of tens of milliseconds for ad serving or fraud scoring, more for heavier recommendations — and the system is designed and sized to stay under it, then measured continuously with alerts on breach.
