How To Check If Code Is Generated By Chatgpt

How To Articles

Have you ever encountered a section of code and questioned if it was created by ChatGPT? As a language model powered by OpenAI, ChatGPT has gained significant recognition for its ability to generate text that resembles human writing. In this article, I will demonstrate how to verify if code is produced by ChatGPT and share some personal perspectives on the procedure.

1. Analyzing Code Structure

One way to determine if code is generated by ChatGPT is by analyzing its structure. ChatGPT tends to produce code that follows certain patterns and conventions. Look for unique identifiers or variable names that are commonly used by ChatGPT. Additionally, pay attention to the overall organization and indentation of the code, as ChatGPT often generates code with consistent formatting.

However, it’s important to note that analyzing code structure alone may not be sufficient to definitively identify if it was generated by ChatGPT. Other coding styles or frameworks may exhibit similar patterns, so it’s crucial to consider additional factors.

2. Identifying ChatGPT-Specific Language Patterns

ChatGPT has been trained on a wide variety of text sources, including code snippets. This training allows it to generate code that resembles human-written code in terms of syntax and API usage. However, there are certain language patterns and quirks that can sometimes give away its AI origins.

Pay attention to the use of comments within the code. ChatGPT tends to add comments that sound more conversational or explain the code in a verbose manner. While this is not definitive proof that the code is generated by ChatGPT, it can be a strong indicator.

3. Contextual Understanding

ChatGPT is designed to generate text based on the given context. When it comes to code generation, it can incorporate contextual understanding to some extent. If the code appears to be contextually aware and makes references to specific variables or functions mentioned earlier in a conversation, it is likely that ChatGPT was involved in its generation.

Consider the use of external libraries or frameworks in the code. ChatGPT might generate code that incorporates popular libraries or frameworks, even if they are not explicitly mentioned in the initial prompt. This is because ChatGPT has been trained on a wide range of code snippets that often include these libraries.

4. Comparing Against Known ChatGPT Outputs

One effective way to check if code is generated by ChatGPT is to compare it against known outputs. OpenAI has made some of ChatGPT’s outputs available for study and analysis. By comparing the code in question with these known outputs, you can look for similarities in code structure, language patterns, and contextual understanding.

OpenAI has also released a research paper detailing the development and capabilities of ChatGPT. This paper provides insights into the model’s training data and the techniques used to fine-tune it. By familiarizing yourself with the characteristics and limitations of ChatGPT, you’ll be better equipped to identify its generated code.


Identifying code generated by ChatGPT can be a challenging task, but by analyzing its structure, identifying specific language patterns, considering contextual understanding, and comparing against known ChatGPT outputs, you can increase your chances of recognizing its involvement.

It’s important to keep in mind that code generation by AI models like ChatGPT raises ethical and legal concerns. Proper attribution and understanding the limitations of AI-generated code are essential. As the field of AI continues to evolve, it’s crucial to remain cautious and responsible when working with AI-generated code.
