NEW! Citing Information Generated by ChatGPT/AI

Other AI-generated text can be cited similarly. For more details, visit CMOS FAQs.

Footnote or endnote Format:

1. Text generated by ChatGPT, March 31, 2023, OpenAI, https://chat.openai.com.

If the prompt has not been included in the body of the text, it can be included in the note:

Author-Date Format:

If you’re using author-date instead of footnotes or endnotes, any information not provided  in the body of the text would be placed in a parenthetical text reference. For example,
