Chicago Guide to Citing AI

Just like with other sources, you must cite any content you are using from an artificial intelligence generator like ChatGPT. Instructors will have different policies regarding the use of AI, so if it is allowed, you must cite the AI tool used. 

Just keep in mind if you are using AI text generators for writing help:

  • If AI is being used to help outline or draft a paper (and it is o.k. with your instructor to use AI for this purpose), you will need to acknowledge at the beginning or end of the paper the role AI played in its creation. For example, "This paper was produced with drafting support from Microsoft Co-Pilot." If AI was used extensively, you will want to explain how it was used. This can be included in the Methodology section of a more formal research paper.  
  • If you are citing a conversation with an AI tool as a source, or as part of your study, follow the Chicago style guidelines for citing artificial intelligence content. 

Chicago Style Guidelines for Citing Content Generated by Artificial Intelligence

  • Author - The AI tool is the author and if you are including it as part of a note, it could say, "Text generated by ChatGPT."
  • Date - Include the date the content was generated.
  • Publisher - Use the company that created the AI (e.g. OpenAI, Google).
  • Location - Provide the URL and if possible provide a URL for the specific content. Be aware of the link being publicly available as you should not include any links that require a login to access. A citation for AI content in a bibliography or reference list should ONLY be included if the URL is publicly available. 

Note - in Chicago, a prompt should be included, either within the text, or if it is not part of the text, it can be included in the note. 

Examples

For many types of writing it is sufficient to include the AI tool acknowledgement in the text:

The following recipe for pizza dough was generated by ChatGPT.

Footnote or Endnote for a formal citation:

1. Text generated by ChatGPT, OpenAI, March 7, 2023, https://chat.openai.com/chat.

Footnote or Endnote if the prompt is NOT included in the text:

1. ChatGPT, response to “Explain how to make pizza dough from common household ingredients,” OpenAI, March 7, 2023.

 

Citing AI-Generated Images:

Chicago recommends that you cite AI-generated images like any other image and include the name of the AI tool, the AI company, and the prompt that generated the image.  

Example:

“A modern office rendered as a cubist painting,” image generated by OpenAI’s DALL·E 2, March 5, 2023.
