How verdicts are scored

Every piece of content gets one score between 0 and 1 and a label: ai at 0.7 or above, uncertain from 0.4, and human below that. The card shows the score as a percentage with a ten-segment bar.

The order of precedence

1. Provenance first. If any provenance detector ran and asserted that the content is AI-generated, the score is at least 0.9. A trusted Content Credentials signature declaring "trained algorithmic media" scores 0.97, IPTC "trained algorithmic media" 0.95, a matching EXIF generator tag 0.9, and a composite that includes AI media 0.8 (which then rises to the 0.9 floor). These are cryptographic or declared facts, so they win. See Content Credentials and EXIF and IPTC metadata.
2. Then the generator classifier. With no provenance signal, a pixel classifier's probability is the score. When a model recheck also exists the two are blended: 60% classifier, 40% recheck.
3. Then the recheck alone. If only a model recheck exists, its probability is the score.
4. Then writing patterns and the community. For text with none of the above, the on-device writing-pattern score is used; once three or more community reports exist it is blended 75% pattern, 25% report ratio.

Text under 40 characters is scored 0.1 and noted as too short.

What the circle uses

The circle appears when the score is at or above your sensitivity preset (95%, 90% or 70%), which is separate from the 0.7 verdict line. See Sensitivity presets.
