Activity Aim & Talk

In this activity, Guangsheng Bao will talk about Fast-DetectGPT. Large language models like ChatGPT and GPT-4 have brought convenience to people’s work and lives across various sectors. However, concerns about their misuse, including issues like fake news, malicious product reviews, and plagiarism, have also arisen. This paper introduces a novel text detection method Fast-DetectGPT that operates without training and utilizes open-source small language models to detect text generated by various large language models. Fast-DetectGPT increases the detection speed by 340 times and improves the detection accuracy by 75% relative to previous methods, establishing it as the new state-of-the-art (SOTA). In the detection of text generated by widely used models such as ChatGPT and GPT-4, it surpasses the accuracy of the commercial system GPTZero. Fast-DetectGPT achieves high accuracy, high speed, low cost, and versatility, clearing the hurdles for practical application.
