Software:GPTZero

GPTZero is an AI-generated content detection system designed to identify and analyze artificially generated text, specifically focusing on text produced by AI language models like GPT-3. As the prevalence of AI-generated content increases, GPTZero aims to help maintain trust and accuracy in the digital domain by distinguishing between authentic and human-generated material.

Development

GPTZero was developed by Edward Tian, a Princeton University undergraduate student, in response to concerns about AI-generated content in academia and its potential impact on plagiarism. Leveraging machine learning techniques and NLP algorithms, GPTZero is capable of analyzing and classifying content with high accuracy.

The development process involved collaboration with AI experts and extensive testing on various datasets, including AI-generated content from GPT-3 and human-generated content. GPTZero has received attention from academic institutions, news outlets, and the broader AI community for its ability to detect AI-generated content, which is essential for ensuring the integrity of academic work and other text-based content.

Functionality

GPTZero uses «perplexity» and «burstiness» to determine if a passage was written by a bot.

In order to properly understand what constitutes "perplexity" and "burstiness," artificial intelligence has been trained through the analysis of an incredibly large amount of human work.

Perplexity is how random the text in the sentence is, and whether the way the sentence is constructed is unusual or “surprising” for the application. It relies on language models, and the more such models, the higher the chance that the text was not written by a person.

Burstiness compares sentences with each other, determining their similarity. Human text is more discontinuous, meaning we tend to write with more sentence variation than AI. Thus, if this variability does not correspond to the needed level, there is a high probability that the text is artificially composed.

GPTZero is functional at several levels, starting from documentary (general text analysis) and ending with a narrower one, when you can check the likelihood of using AI at the sentence level. This, in turn, does not always indicate directly that the amount of artificially created text prevails over human writing, but, nevertheless, it indicates the area in which an attempt to apply GPTZero should be sought.

GPTZero Case Study: Models and Exploits:

On 1^st February(2023), the team of GPTZero found one possible GPTZero exploit 'GPTZero By-passer' software through tiktok. Key letters in the essay text were changed by the by-passer program to Cyrillic, which appears the same to humans but is radically different to computers.The team decided to look into GPTZero by-passer .

First, they used ChatGPT to create a few paragraphs of AI text and then ran it through the  GPTZero by-passer software. The text generated, was then copied and inserted into GPTZero.

Initially, The GPTZero by-passer exploit succeeded in tricking GPTZero because the results said that the text is generated by a human and not an AI.

On February 2, the by-passer exploit was fixed as part of one of their routine model upgrades. The update altered the by-passer's character token changing mechanism.

GPTZero now recognizes the texts as AI produced, even with the by-passer update.
