AI feature appeared functional due to metric error, but was dead for a day

A developer encountered a critical issue where their AI feature appeared to be functioning correctly based on metrics, but was actually dead for an entire day. The problem stemmed from a mislabeled counter that conflated two distinct outcomes: the AI's output being rejected by a safety gate, and the AI model failing to respond entirely due to a slow reload time. This misinterpretation led to the false conclusion that the safety mechanism was working, when in reality, the AI feature was inert. The fix involved keeping the model resident in memory, increasing the timeout, and crucially, splitting the counter to accurately distinguish between accepted, rejected, and unanswered AI outputs.

    My AI Feature Was Dead for a Day. The Metric Said It Was Working.

    <p>Yesterday my drone early-warning demonstrator recorded four AI-generated explanations. All four were discarded by the validation gate that sits in front of them.</p> <p>I looked at that number and felt good about it. A gate that rejects four out of four is a gate doing hard wo…
