The detector will be built by fine-tuning a DistilBERT classifier, a method similar to Pangram models, which are believed to power Substack's AI detection feature.

Here, we are going to develop a method similar to Pangram models, which, as far as I know, are behind Substack AI detection feature. ... For this, we are going to fine-tune a DistilBERT classifier (similar to what I described in one of my early Substack articles, Finetuning Large Language Models), but more details on that later when we get to that stage.
