- What happened
- Researchers developed a machine learning classifier using stylometric features to detect ChatGPT-assisted student writing, achieving 0.87 ROC-AUC on held-out test data.
- Why it matters
- Educators and academic integrity teams evaluating submissions need detection tools, particularly when manual review is impractical at scale.
- Watch out
- The model shows 22.2% false positive rate, meaning legitimate student writing gets flagged as AI-assisted, risking unfair accusations without human verification.

- Machine Learning Model-Based Routing
- Memory Reading/Writing Operations
Each one covers how the technique works, when it earns its cost, and where it breaks.
