GPTinf Description
AI detection involves the use of advanced machine learning algorithms and model to identify AI-generated material. The primary goal of a text detector is to identify specific characteristics. A typical AI detector uses a language model that is similar to the models used by AI writing tools. Detectors look at two things: perplexity and the business. The lower the score, the more likely it is that the content was generated by AI. Perplexity is a measure of how unpredictable content can be, i.e. how likely it is for a reader to get confused. AI tools such as ChatGPT produce content that is low in perplexity. Texts are readable and make sense, but they're also predictable. Human writing is more perplexing.
