latency targets are now product promises not infra metrics

Interactive AI workflows are making latency an explicit user contract; long or volatile responses now feel like broken behavior rather than technical variance (Google web vitals).

expectation reset

Users compare assistants to real-time interfaces, so perceived delay now influences trust as much as output quality.

operating consequences

  • Product teams set latency SLOs by workflow criticality.
  • Routing and cache policy are now UX levers.
  • Tail latency failures drive churn in recurring tasks.

my take

Latency discipline is now part of product truthfulness.
