On January 3, 2023, Edward Tian, who developed GPTZero as his thesis project, released the tool. After five months, the freemium AI-detection application had an astounding 1.2 million users; as of the posting, it had 2.5 million users. However, that isn’t why Tian was a 22-year-old Princeton computer science senior. It results from the tool’s goal and mission of identifying AI material.
The slogan “Humans Deserve the Truth” and the app’s name speak for themselves. Thus, to combat ChatGPT abuse, GPT Zero looks for text created using AI tools like ChatGPT, GPT-3, GPT-4, and LlaMA, a large language model (LLM) developed by Meta AI. Additionally, they have raised $3.5 million in capital funds.
GPTZero is an AI-generated content detection system that Edward Tian and GPTZero Technologies developed. It is specifically designed to identify and analyze artificially generated text, focusing on text produced by AI language models such as GPT-3, GPT-4, and ChatGPT.
GPT Zero works by analyzing text for two fundamental properties: perplexity and burstiness. Perplexity is a measure of how random or unpredictable a text is, while burstiness is a measure of how evenly distributed the randomness of a text is. AI-generated text typically has a higher burstiness score than human-written text, as language models tend to generate text in batches.
How Does GPTZero Work?
GPTZero works by analyzing text for two fundamental properties: perplexity and burstiness.
- Perplexity is a measure of how random or unpredictable a text is. A high perplexity score indicates that the text is more difficult for a language model to predict and is more likely to be human-written.
- Burstiness is a measure of how evenly distributed the randomness of a text is. A high burstiness score indicates that the text has large sections that are very random, followed by large sections that are very predictable. This is a characteristic of AI-generated text, as language models tend to generate text in batches.
- Complexity rating: Perplexity is a randomness metric, as was previously mentioned. It tests the predictive power of a language model (such as ChatGPT) to determine what will be said next. Higher scores suggest that a text is human-made since it shows unpredictability. Perplexity is currently based on the GPT-2 model in GPT Zero.
- Burstiness ranking: This measure assesses if there is consistency or pattern in the distribution of sentences. It is predicated on the notion that when people write, they frequently combine short and long sentences.
- AI writes highlighted text: The most recent version of GPT Zero has phrase detection. The app indicates which sentences were written by artificial intelligence within a manuscript. Moreover, GPTZero will display the sentence with the highest perplexity score.
- Integrating APIs: The API for GPT Zero was made easily accessible by the inventor for those wishing to include it in their systems. Email requests for customization support can also be sent to the app’s engineers.
- No cost to use
- able to recognize GPT-2 texts
- No need to register
- Currently in beta testing
- That is not true.
- Absent features
It would be unfair to point out the tool’s shortcomings, as it is currently in beta testing. Instead, we can concentrate on GPT Zero’s expected future direction. To begin with, teachers can efficiently utilize the app because it is now free. For those who make a request, the API is also accessible. This implies that other developers can expand and integrate it with other systems.
Unlike many AI content identification technologies on the market that are made for blog posts and marketing copy, Edward Tian stated from the start that the programme was created with academics in mind. The accuracy of GPTZero is expected to rise as the team evaluates it with more student work data. When used with internet plagiarism detectors, it can enhance the integrity of student theses and essays.
While the GPTZero is still being developed, educators should utilize it cautiously for the time being. AI detection is only “one of the many pieces of a holistic assessment of student work,” as the app tells users on its page. Moreover, plagiarism detection systems that check manuscripts against billions of publicly accessible web pages are available.
Who Creates the GPTZero?
These days, the amount of information produced by machines or artificial intelligence has grown thanks to models and technologies like GPT-2, GPT-3, and even ChatGPT. It’s getting harder to distinguish this artificial material from human creations.
Thus, to solve this issue, Princeton University computer science student Edward Tian created GPTZero, released on January 2, 2023. This tool aims to identify artificially generated essays and other written content.
How Is It Operated?
According to the creator of the GPTZero software, it can rapidly and accurately identify if an essay was authored by ChatGPT or by a person. The two characteristics, “burstiness” and “perplexity” in GPTZero, will assist you in distinguishing between content generated by ChatGPT and content written by humans.
Text complexity is quantified using a statistic called perplexity. GPT Zero measures perplexity using the GPT2 model. Reduced confusion suggests that the material is more machine-generated because it is easier to understand. On the other hand, text that humans have handwritten tends to be more confusing and unpredictable.
Conversely, burstiness quantifies the degree of randomness in the text’s writing. In this manner, GPT Zero can reliably determine whether a ChatGPT or a human author created a text.
Take note: Results from the app will be more accurate the more content you enter. Furthermore, remember that GPTZero is currently in beta, so you shouldn’t rely solely on it.
Perplexity: The degree to which your text deviates from predictability. Text is processed by the model using GPT-2 (345 million parameters). Although the exact range of perplexity is unknown, values near 0 are certainly produced artificially, while values near 100 are more likely to have been authored by humans.
Burstiness: The phenomenon of uncommon objects sporadically emerging in clusters throughout time (also known as creative variability). Regarding machine-generated content, confusion is uniformly distributed and constantly low. You’ll observe that human writing inherently contains more diversity, making it less predictable from patterns.
Can GPTZero be trusted?
It has been said that GPT Zero is susceptible to trickery. I requested ChatGPT to create a short story on the book The Old Man and the Sea as if it were a high school student after the recommendation of Reddit user Smellz_Of_Elderberry. It didn’t fool GPT Zero.
- ChatGPT writes as though it’s a student in high school.
- Picture used by permission of the owner of the copyright
- I gave it another go, changing a few little mistakes like the verb tense and placement of punctuation, but GPTZero still said, “Your text is likely to be written entirely by AI.”
- The word “likely” is crucial here, as the creator never claimed that GPTZero was flawless. Anecdotally, GPT Zero is functioning well for the majority of users. However, its accuracy is still being evaluated.
Constraints and Upcoming Improvements for GPTzero:
Although not flawless, GPTzero shows promise in identifying duplicate information in research publications produced by ChatGPT.
The detection algorithm’s accuracy still needs improvement, especially when identifying paraphrasing and rewording previously published information. Furthermore, since GPTzero is still a relatively new technology, there is still a lot of space for advancement and development.
Assistance and Society:
With over 4.3K members, GPTZero Educators is a Facebook community run by GPT Zero. As anticipated, the majority of them work in the field of education. Typically, the subjects cover how to use ChatGPT to prevent students from cheating. You can use their contact page to send them a note if you require technical support. Additionally, GPT Zero is open to feature requests.
One of the many benefits of GPTZero is its capacity to identify plagiarism produced by artificial intelligence (AI) due to the increased demand for ChatGPT. In addition, the tool’s website crashed from excessive usage, proving that GPT Zero is in high demand.
GPT Zero is an excellent resource for anyone wishing to avoid AI plagiarism brought on by ChatGPT. We will conclude this essay and hope you found it helpful and instructive. If you have any questions, you can post them in the section below the comments. We would be happy to address your questions.
