Sliced, rotated, emoji-covered: AI image detector Pangram easily fooled

goodside · x · 2026-11-14

goodside tested the Pangram AI-image detector by slicing a ChatGPT-generated image into four pieces, randomly transforming and rotating each with a different color filter, then layering them over a real nature photo partially covered by garish text and emojis. The detector failed — in the screenshot it only marks three dashed regions and the overall score leans toward "No AI signal".

A concrete demonstration that mainstream AI-image detection has poor robustness to trivial adversarial edits, undermining confidence in detector-based AI content moderation.
