What happened
NeurIPS partnered with the AI-text detector Pangram to enforce a human-authorship rule on its position-paper track and published the numbers.
Why it matters
It was the first major ML venue to desk-reject papers at scale based on an AI-text detector. That is a precedent for detector-based enforcement, with the usual false-positive risks.
