Threshold
In AI detectors, the cutoff point that converts a continuous probability score into a binary judgment. Different tools set this value differently, so the same piece of text may be classified as AI-generated or human-written depending on the detector and its chosen threshold.

In content moderation, lowering the threshold increases recall but also increases false positives, while raising it does the opposite, and this parameter choice determines which types of political expression are more likely to be restricted.
The default 0.5 threshold is not the optimal solution for any metric; threshold choice should be based on the cost of misjudgment—when missing positive samples is costly, move the threshold left to raise recall, and when false positives are costly, move it right to raise precision.
Raising the confidence threshold lowers the error rate but increases misses, and lowering the threshold does the opposite; teams need to choose an acceptable operating point.
The author's generator output has a threshold that lands roughly between 140 and 160 on a 0-255 scale.
A threshold is the cutoff point at which a detector converts a continuous probability score into a binary AI-or-human judgment; different tools use different thresholds, some set at 50%, others at 70% or even 90%.
A higher threshold is not always better; setting it too high will push a large number of requests back to human agents, so an appropriate balance point needs to be found.
