SynthID Text Provenance Verification & Grounded Rules
Evaluates keyed g-function pseudo-random signals across token contexts under authorized deployment configurations. Strictly decoupled from editorial authoring.
- SynthID Text is a keyed logits watermark, NOT a universal AI writing detector.
- No watermark detected does NOT establish human authorship.
- Never infer "XX% AI written" from a Bayesian posterior probability.
- Detection results must never be used as sole disciplinary evidence.
