Can Teachers Detect GPT4?

Teachers can detect GPT-4 content that is generated using simple prompts. However, if the GPT-4 generated content is produced using advanced prompts or rephrasing techniques such as Quillbot or extensive manual rewriting, it becomes significantly more challenging for teachers to detect GPT-4 content.

Situations In Which Teachers Can Detect GPT4 Content

There are situations where teachers can easily detect if a student has used GPT-4 to generate their content. Let’s explore some of these cases:

1. When You Simply Generate GPT4 Content And Paste:

If you directly go to GPT-4 and ask it to explain a simple concept, such as “What is gravitational force?” or any other topic, it will generate high-quality content. However, developers of AI content detectors are well aware of these AI models and keep updating their detection methods accordingly.

AI content detectors now have access to databases that can identify the latest GPT models. So, if a student simply copies and pastes GPT-4 generated content without any modifications, it can be easily recognized by teachers using those tools.

Moreover, Teachers have the experience and knowledge to recognize when students rely on AI-generated content rather than their own comprehension of the subject matter. 

Suppose a student has to write an essay about photosynthesis. Instead of researching and understanding the topic, they decide to use GPT-4 to generate the content.

If the teacher notices that the essay contains advanced vocabulary, complex sentence structures, and accurate explanations beyond the student’s usual level of proficiency, it can raise suspicions that the content was not written by the student.

In such cases, teachers may compare the student’s previous work and writing style with the GPT-4 generated content. They can identify discrepancies and inconsistencies that indicate the usage of AI-generated content.

2. When You And Other Students Have Very Similar Answers:

Another case where teachers can detect GPT-4 content is when multiple students have very similar answers. Let’s delve into this scenario:

Teachers often assign the same tasks to a group of students. If several students submit assignments with remarkably similar answers, it raises suspicion that they might have used GPT-4 or other AI models to generate their content.

For example, let’s say the teacher asks the class to write a short story about a magical adventure. If several students’ stories have identical plotlines, characters, and even specific phrases, it suggests that they might have relied on AI-generated content.

Teachers can easily spot this pattern when they compare the submissions side by side. They may notice that the language, ideas, and structure of the stories are strikingly alike. 

This similarity is highly unlikely if each student genuinely created their story without relying on AI assistance.

To further validate their suspicions, teachers may engage in discussions or ask questions about specific elements in the students’ work.

If students struggle to explain or elaborate on their stories, it indicates that they may not have a deep understanding of the content, further supporting the possibility of AI usage.

Situations In Which It Can Be Challenging For Teachers To Detect GPT4

1. When You Rephrase The Content Using Tools Like QuillBot

Using tools like QuillBot, which can paraphrase the text, can make it challenging for teachers to detect GPT-4 generated content.

These tools rephrase the original text, changing the sentence structure and wording while preserving the core meaning.

As a result, the content may appear more authentic and less likely to be flagged by AI content detectors.

2. When You Write The Content In Your Own Words Or Use Advanced Prompts

If students manually rewrite or paraphrase GPT-4 generated content using their own words, it can make detection more challenging. 

By incorporating their unique writing style, vocabulary, and sentence construction, students can make the content appear as if it is their original work. 

Additionally, using advanced prompts can guide GPT-4 to produce content that aligns more closely with a student’s thoughts and ideas, making it harder for teachers to detect the AI-generated nature of the content.

Why Is GPT4 Detected By AI Content Detectors?

If you’ve been using ChatGPT or even the more advanced ChatGPT-4 to generate content, you may have noticed a pattern in the word choices it produces. This pattern is what allows AI content detectors to identify when ChatGPT-4 has been used.

AI content detectors rely on predicting word choices in the generated text. They analyze the language patterns and compare them to known patterns of AI-generated content.

One tool that demonstrates this is GPTZero. By pasting any GPT-generated content into GPTZero, you will receive scores for perplexity and burstiness.

Perplexity measures the level of randomness or unpredictability in the text. A lower perplexity score means the text is more predictable and less random.

Burstiness, on the other hand, measures the variation in perplexity throughout the text.

In simple terms, both scores indicate how random the word choices are in a given text. AI-generated content, including ChatGPT-4, tends to have lower perplexity and randomness scores because the word choices are more predictable.

You may have observed that ChatGPT-4 often generates specific text in a certain way, using predictable phrases or structures.

In contrast, when a human writes, they tend to use more varied word choices, making the text feel more natural and resulting in higher perplexity and burstiness scores.

However, it’s important to note that AI tools like ChatGPT-4 can learn specific writing styles. With advanced prompts, they can generate content that becomes harder to detect by AI content detectors.

This means that as AI models advance, the detection methods employed by AI tools also need to evolve to keep up with the changing patterns.

Why Can Teachers Detect GPT4?

Even if you rephrase GPT-4 generated content, the essential facts will still remain the same. This becomes noticeable when multiple students use GPT-4 or any ChatGPT model to generate their content.

Let’s consider an example where the class is given an essay writing assignment.

If the core facts in the essays of several students match up, it raises suspicion for the teacher whether the content has been generated by an AI.

Only when you input your own unique thoughts and ideas about the essay topic and use advanced prompts to generate the content, can you potentially bypass AI detection or the teacher’s detection. Otherwise, there is always a risk of being detected by AI.

To illustrate this further, let’s imagine the class is asked to write an essay on climate change.

If multiple students end up with essays that contain the exact same arguments, examples, and evidence, it suggests that the content may have been generated using an AI model like GPT-4.

This similarity among the essays would be highly unlikely if each student had independently researched and written their own assignments.
