Despite careful review, it may still contain mistakes, omissions, or out-of-date information. Whether you are new to the topic, a team lead, or a senior practitioner, treat it as a starting point rather than an authoritative reference: read it critically and independently verify anything you act on (code, commands, figures, and factual claims) against official documentation and primary sources before relying on it.
What it is#
Manual review minutes measure the human time spent checking model outputs in a human-in-the-loop pipeline — analysts working a review queue of flagged or low-confidence predictions, confirming or correcting each. It is the labor cost of keeping a model’s decisions trustworthy.
Why it matters#
Human review is expensive — expert annotation runs to tens of dollars per hour, and for some systems this labeling / review cost dwarfs the compute cost. It is a real budget line, not a rounding error, and it scales with how many cases the model sends to a person.
The lever#
Fewer needless escalations means fewer review minutes, so precision and a well-tuned selection rate (the share of cases flagged) directly control the cost. The design trade-off is automation vs assurance — routing more to humans is safer but slower and pricier; routing less is cheaper but riskier.
