Sebastian Raschka published a tutorial demonstrating how to build an AI text detector by fine-tuning a DistilBERT classifier, framed as an educational project for studying the limitations of AI detectors1. The tutorial also covers training a small language model to produce text that avoids detection using a verifier-based approach. Raschka noted that Substack recently launched a built-in AI detector feature in its UI, citing it as motivation for the project. The project includes an AI-detector API and a user-friendly UI.
