Heuristic signals
Results are evidence scores, not proof of origin. The model is optimized to prefer UNCERTAIN over false accusations when evidence is weak.
- Format conversion alters noise and frequency signatures and may increase false-positive rate.
- Messenger compression (WhatsApp, Telegram, etc.) re-encodes and strips metadata — photos saved from chats may show AI evidence even when real.
Model Card
v5.9.0
- Decision bands
- AI evidence >= 64%, real-photo evidence <= 55%, otherwise UNCERTAIN.
- Runtime
- Browser-only. A deep EfficientNet-B0 classifier (ONNX, WASM) is the primary signal, weighted above the heuristic + k-NN mini-ML and safety caps. If the model fails to load, the detector falls back to the heuristic + k-NN ensemble.
- Limits
- Small, heavily compressed, screenshot-like and converted files should be treated as low evidence.
