What Did the Researchers Find?
Using screening technology and three AI classifiers, the CopyLeaks team studied texts from Claude, Gemini, Llama, and OpenAI.
The classifiers identified what the company call “subtle stylistic features” like sentence structure, vocabulary, and phrasing. For a classification to be made, all three classifiers had to “agree,” delivering what CopyLeaks says was a “99.88% precision rate and just a 0.04% false-positive rate, accurately identifying texts from both known and unknown AI models.”
