OpenAI calls its new tool a “fine-tuned GPT model that predicts how likely it is that a piece of text was generated by AI from a variety of sources, such as ChatGPT.”
It has some limitations – most notably the results may be inaccurate. OpenAI primarily trained the tool on English content written by adults so it’s entirely likely there will be false positives. Also, as OpenAI pointed out, it’s easy to edit AI-generated text to pass as human-generated. As noted in its FAQ section:
“The results may help, but should not be the sole piece of evidence, when deciding whether a document was generated with AI. The model is trained on human-written text from a variety of sources, which may not be representative of all kinds of human-written text.”
The results of the classifier. After you paste your text into tool (Open AI says you need a minimum of 1,000 characters, which is roughly 150-250 words) the AI Text Classifier will evaluate whether the text was generated using AI. You will see one of five labels:
Very unlikely.
Unlikely.
Unclear if it is.
Possibly.
Likely.
