The most important number an agent produces isn’t its answer — it’s how sure it is. Compose that number from independent signals, check it’s calibrated, grade the high-stakes calls with a second model, and route the rest to humans well.

This is Level 3 of a six-level maturity model for running LLM systems in production. Levels 1 and 2 got you to where the system works and you can see it working. Level 3 is confidence : the system acts on its own only when its calibrated confidence is high, grades the decisions that matter with an independent judge, and routes everything it’s unsure about to a human in a way that actually catches errors.

These three things are one mechanism. Confidence is the dial that decides what runs automatically. A judge is one of the signals that dial is built from — and the trigger that pulls a decision off the automated path. The human handoff is where the dial sends everything below the line.…
