Introduction

As the usage of tools like ChatGPT increases, there is a significant outbreak of AI-generated content available on the internet. Whether you are a university professor or someone who doesn't like seeing AI-generated content on your feed, a major challenge you face is distinguishing between human-written content and AI-generated content. This is a problem everyone has been grappling with. A new solution has emerged: GPT detector, specifically called GPT-0.

GPT-0 is a service that can help you detect content generated by GPT models. Unfortunately, it is not open source, and the creator is likely developing a paid version for academia. However, the current version of GPT-0 is free and promised to remain permanently free. GPT-0 is a Streamlit application hosted on Streamlit Cloud. Although the code isn't public, it utilizes several techniques to detect whether text was written using GPT.

This tool can be used not just for ChatGPT but for any AI-generated content using the GPT family of models, including GPT-2, GPT-3, GPT-3.5, and InstructGPT. If you have text generated from any GPT model, GPT-0 should be able to classify it as AI-generated.

I’ve tested various texts, and I found GPT-0 to be quite effective. Here’s how it works and how you can use it:

How GPT-0 Works

  1. Text Analysis: You paste your text into the application.
  2. Perplexity Measurement: The tool calculates "perplexity" which measures the randomness and coherence of the text. AI-generated text usually has a lower perplexity compared to human-written text.
  3. Burstiness Analysis: This is the variation in perplexity among sentences. Human-written content tends to have a varied perplexity while AI-generated content shows more uniformity.

Example

Human-Generated Text: I went to the Microsoft blog, copied a text, and pasted it into GPT-0. The average perplexity was 26, indicating it was likely human-generated because the perplexity was too high for it to be AI-generated.

**AI-Generated Text:** I used text generated by ChatGPT and pasted it into GPT-0. The perplexity was 12, significantly lower than the human-generated text, and the burstiness was uniformly distributed. The result confirmed that the text was AI-generated.

GPT-0 uses perplexity and burstiness to detect AI-generated content effectively. Although the code for GPT-0 isn't available, the formula used is straightforward and should be easy to replicate. While Open Source alternatives might be scant, this application remains a robust solution.

FAQ

Q1: What is GPT-0? A1: GPT-0 is a service that helps detect AI-generated content, particularly those created using GPT models like GPT-2, GPT-3, GPT-3.5, and InstructGPT.

Q2: Is GPT-0 free to use? A2: Yes, the current version of GPT-0 is free and is promised to remain permanently free by its creator.

Q3: How does GPT-0 detect AI-generated content? A3: GPT-0 uses two main techniques: perplexity and burstiness. Perplexity measures the randomness and coherence of the text, while burstiness looks at the variation in perplexity among sentences. AI-generated content tends to have lower perplexity and more uniform burstiness.

Q4: Where is GPT-0 hosted? A4: GPT-0 is a Streamlit application hosted on Streamlit Cloud.

Q5: Can GPT-0 detect content generated by all GPT models? A5: Yes, GPT-0 can classify text generated by any model in the GPT family, including GPT-2, GPT-3, GPT-3.5, and InstructGPT.

Q6: Is the code for GPT-0 open source? A6: No, the code for GPT-0 is not publicly available. However, the techniques it uses are well-documented and could be replicated.
