What this gate checks
The receipt image must not be generated by an AI image model.
Under the hood: A vision model (Gemini) scores the image for AI-generation probability on a 0–1 scale. Scores at or above 0.65 fail. Lower is better.
Common failure reasons
- Image was generated by Midjourney, DALL-E, or another AI image model
- Heavily filtered or stylized photo that triggers the detector
- Photo of a screen displaying a receipt
How to pass this gate
Photograph a real physical gas receipt with your phone camera. Do not use any AI image tools. Avoid heavy filters or post-processing.
