The LLMOps loop

The lifecycle that closes the reliability gap: evaluate, deploy, observe, improve — and why it's a loop, not a launch.

Traditional software ships on a line: build → test → deploy → done. AI features run on a loop, because the four gap-sources from the last lesson never stop operating. LLMOps is that loop, and the whole course is one turn around it.

   Every real failure in OBSERVE becomes a case in EVALUATE.
   The loop tightens over time — or the feature rots.

The four stations

  • Evaluate — measure quality against a golden set before shipping. You know this from three courses; LLMOps makes it continuous and automated (Module 2).
  • Deploy — ship a specific, versioned configuration behind a gate, with the ability to roll back. Not 'update the prompt in production' — a controlled release (Module 4).
  • Observe — capture what actually happens on real traffic: traces, metrics, failures. Not 'is it up' but 'is it right, fast, and affordable' (Module 3).
  • Improve — feed real failures back into the eval set, fix, re-evaluate, redeploy. The failures you find in production are the test cases you were missing.

Why it must be a loop

A launch is a snapshot; the reliability gap is a moving target. Model updates, corpus growth, and shifting user behavior guarantee that a system correct at launch drifts out of correctness — silently. The loop is what converts that inevitability from 'we found out when a customer complained' into 'our Tuesday eval run caught it and the gate held.' Teams with the loop improve every week and know they're improving; teams without it ship once and slowly degrade in the dark.

You've been doing turns of this loop already

Every 'run the golden set, read the flips, ship or revert' cycle from the prior courses was one hand-cranked turn of this loop. LLMOps is the discipline and tooling that makes it turn automatically, continuously, and across a whole team — so it keeps turning after you've moved on to the next feature.
