Discover the OFFICIAL OpenAI AI Classifier for Detecting AI Text such as ChatGPT” – A Must-Read for AI Enthusiasts!

Artificial Intelligence (AI) has taken the world by storm, and it is challenging to differentiate between human and AI-generated text. But the problem has been solved! Open AI, the San Francisco-based organization founded by Elon Musk, has released its official AI Classifier, and it is creating a buzz in the entire AI industry. In this article, we will walk you through the essentials of the OpenAI AI Classifier and how it can help distinguish between human-written text and text produced by AI.


The AI text generation Landscape has been advancing, and we can no longer depend on just our intuition to detect whether a text has been generated by AI. However, OpenAI has augmented our ability to differentiate between AI text and words produced by humans. The classifier uses Machine Learning (ML) to recognize whether text has been produced by GPT-2 or a human.

The Official OpenAI AI Classifier

Recently OpenAI launched its own AI Classifier, “GPT 2.5B,” that can differentiate between machine-generated text, such as GPT-2, and text written by a human. The tool offers people with the means to identify information or misinformation campaigns intended to influence public opinion or detect academic dishonesty. The model is trained using a fine-tuning procedure on top of the GPT generator to predict the likelihood of text being generated by AI or a human.

How the classifier works

The classifier analyzes the wording, phrasing, and syntax of text provided by the user and identifies whether it was created by a human or generated by GPT-2. The classifier works by comparing the input with a large set of texts generated by the GPT-2 model and human-written text using Linear Support Vector Machines (SVMs) to discriminate one type of text from another.

Potential uses of the tool

The OpenAI classifier has the potential to be invaluable in identifying misinformation campaigns and instances of academic dishonesty by recognizing where text has been plagiarized. It can also be useful for screening chatbots claiming to be humans in potential fraud cases. For instance, the tool could analyze the customer support chat to identify where a chatbot is pretending to be human.

Other potential uses include:

  • Online Media outlets can use the tool to prevent the spread of misinformation that might have come from bots and not humans.
  • Chatbot developers can use the classifier to identify the words and phrases that make a sentence sound natural.


The classifier isn’t perfect and has its limitations. It can detect texts composed of a minimum of 1000 characters, such that shorter strings of text cannot be analyzed. Also, the classifier is not consistently reliable and favors English, so it can mislabel both human and AI-generated text.


The OpenAI AI Classifier is publicly available on the for feedback, and OpenAI welcomes feedback on its model. It welcomes constructive criticism for better optimization of its model, and that is what makes it one of the best AI model providers in the industry.


As we continue to create more sophisticated machines that generate texts with human-like accuracy, detecting whether text has been generated by AI or a human is becoming increasingly critical. Thanks to OpenAI, we now have a tool that can help us distinguish between the two. There is no denying that the OpenAI AI Classifier has a long way to go before it can be entirely reliable. Nonetheless, it marks a significant step towards achieving a world where we can differentiate between natural language and AI-generated text.


  1. How reliable is the OpenAI AI Classifier?
    The classifier is not 100% accurate, and it has a true positive rate of only 26%.

  2. What is the function of the OpenAI AI Classifier?
    The classifier can differentiate between text written by a human and machine-generated text, such as GPT-2.

  3. Is the OpenAI AI classifier accessible to the public?
    Yes, the tool is publicly available on the for feedback.

  4. Does the OpenAI AI Classifier recognize all languages?
    No, currently, the classifier favors the English language.

  5. What character limit is required for the OpenAI AI classifier to analyze the text?
    The AI text generated should contain a minimum of 1000 characters for the tool to analyze.
