Pangram is a tool positioned for AI content detection, covering the identification of both text and image content.
Pangram's discussion heat on Hacker News was limited, receiving 7 upvotes and 0 comments.
The AI detection tool Pangram gave Druckenmiller's op-ed a 100% probability of being AI-generated.
NeurIPS's Position Paper Track used the third-party proprietary AI detector Pangram to desk-reject 18.4% of all submissions—178 papers in total—without human review or an appeals process.
NeurIPS did not publish any demographic calibration data when deploying the Pangram system.
Independent researchers fed recently published papers by three chairs of that track into the Pangram detector, and the results showed AI-generation probabilities ranging from 24% to 69%.
Pangram's default settings initially flagged 42.7% of submissions as 90%–100% AI-generated.
The organizers reduced Pangram's AI-generation flagging rate from 42.7% to 12.7% by narrowing the text detection window.
