How to read this result
The meter shows which way the model's visual evidence leans. It is a useful signal, not proof of how an image was made.
What ran
The released PE-Core-L checkpoint checked an orientation-corrected, consistently prepared copy of this image on ModelScope's free CPU service. This application does not retain your upload. ModelScope processes the image under its own service policies. Free hosting may sleep or be unavailable.
Where it can fail
Heavy edits, unusual real photographs, partial AI edits, and generators unlike the training data can move the signal in the wrong direction.
A real image can lean AI-generated, and an AI-generated image can lean authentic. Review the image and its source together.
Image ready
Ready for the released checkpoint.
