LLM text detectors fail to reliably identify AI-assisted student writing

A new paper from researchers including Lukas Gehring explores the limitations of current Large Language Model (LLM) text detectors in educational settings. The study highlights that these detectors often fail to accurately distinguish between human-written text and text generated with varying degrees of AI assistance, particularly at intermediate contribution levels. To address this, the researchers propose a contribution-aware evaluation framework and introduce GEDE, a new benchmark dataset with over 12,500 generated essays, to better model realistic human-AI collaboration scenarios and assess detection systems across different policies and models. AI

IMPACT Current LLM text detectors are unsuitable for reliably enforcing academic integrity policies due to their inability to accurately classify AI-assisted writing.

    Limits of LLM Text Detectors in Education

    arXiv:2508.08096v2 Announce Type: replace Abstract: Students increasingly use the assistance of large language models (LLMs) in their academic writing. While slight assistance (e.g., grammar and style correction, as well as feedback) is permitted under most institutional policies…
