Citation Styles

The Chicago Manual of style has recommendations on how to cite AI tools. You need to credit ChatGPT when you reproduce its words within your own work, but that information should be put in the text or in a note—not in a bibliography or reference list. 

For most types of writing, you may acknowledge the AI tool in your text (e.g., “The following recipe for pizza dough was generated by ChatGPT”).

Author-date 

If you’re using author-date instead of notes, any information not in the text would be placed in a parenthetical text reference. 

Example:
“(ChatGPT, July 7, 2023).”

But do not cite ChatGPT in a bibliography or reference list. 

Notes and Bibliography 

If you need a more formal citation—for example, for a student paper or for a research article—a numbered footnote or endnote :

FOOTNOTE FORM

               1. Text generated by ChatGPT, July 7, 2023, Open AI, https://chat.openai.com/chat.

ChatGPT is the author of the content, and the date is the date the text was generated. OpenAI (the organization that developed ChatGPT) is then listed as the publisher or sponsor of the content. 

If the prompt hasn’t been included in the text, it can be included in the note:

                7. ChatGPT, response to “Explain how to make Shepherd's Pie,” July 7, 2023, Open AI.

IN-TEXT EXAMPLE

                The following recipe for Shepherd’s Pie was generated by OpenAI’s ChatGPT, July 7, 2023.

If you’ve edited the AI-generated text, you should say so in the text or at the end of the note (e.g., “edited for style and content”).
