Pangram AI image detector flags an AI image as "No AI" with high confidence

amplifiedamp · x · 2026-10-10

A user posted a clearly AI-generated image that Pangram's image detector classified as "No AI" with high confidence, quipping that he would have interwoven AI and human creativity if he'd had time.

Pangram claims 99.5% accuracy on an internal benchmark, correctly classified all 2,000 human artworks in a WikiArt subset, and reports a 0.16% false positive rate on ReLAION. The tool supports detection of outputs from GPT Image, Gemini's Nano Banana, Midjourney, FLUX, Grok Imagine, plus video models like Kling and Veo. The public misclassification undercuts those numbers and highlights how unreliable AI-image detection remains in practice.
