Latency is a feature

Latency Is a Feature, Not Just a Metric

In a demo, a 10-second wait feels fine. Everyone’s watching something new and remarkable. In production, those same 10 seconds feel like an eternity. Users start wondering if it’s broken, refreshing the page, or walking away.

Latency isn’t just about technical performance; it’s part of the user experience. Every extra second can reduce trust and engagement.

Making AI fast enough for production means:

  • Caching frequent queries.
  • Precomputing common responses.
  • Streaming results so users see progress.
  • Optimizing your model and prompt for speed.

The truth is, latency is invisible in a demo but front-and-center in real use. Treat it as a feature from day one, and you’ll keep more users engaged when the novelty wears off… and keep your project running in production.
