Students should learn how to cite Chat GPT sources they come across during the research for many reasons:

  • Providing credible sources. This activity allows professors and others interested in the research to find the original study and check its credibility. Thus, it’s essential to verify the authenticity of the sources so that you’re not accused of irresponsible usage of ChatGPT.
  • Showing due diligence. Giving credit to other researchers and scholars who previously worked on this topic demonstrates that you take academic assignments seriously and didn’t use fake citations in the work.

There are four steps to cite ChatGPT properly.
  1. Save chat transcripts. When engaging with the AI chat, ensure that readers can access a copy of your conversation, either through an appendix or an online supplement.
  2. Describe your prompts. Always include the prompt used to elicit a specific response from the chatbot. This information will show the evaluators how well you’ve researched material with ChatGPT and formulated the request for a successful outcome.
  3. Add the date of response generation. As the tool has regular version updates, it’s essential to list the time and date when the answer was generated.
  4. Tell how you use the tool. Students should be transparent about using the platform in their research. Don’t forget this, even if you only asked the chatbot to make a paper outline. To be sure not to get into an unpleasant situation, we advise you to use an AI essay checker.

Let’s Start

Without further ado, let’s cover all the nuances.

This image shows the eight different citation styles.

MLA Style ChatGPT Citation

This style is popular among writers and students working on papers in English, literature, cultural studies, and other humanities disciplines. You can use the MLA reference maker to create a proper reference list. Guidelines for MLA citations recommend researchers cite the chatbot whenever paraphrasing, quoting, or referring to the generated content. Students should acknowledge what they used the tool for so they are not accused of AI cheating.

In the MLA format, it’s vital to check the sources quoted by the platform. In MLA, in-text ChatGPT quotes include reduced versions of the prompts used in quotation marks with parentheses. Begin with the text in quotes, then “ChatGPT,” its version, “OpenAI,” the date of the generated response, and its URL.

MLA citation template“Exact prompt you used.” ChatGPT, Version number, OpenAI, Date of response. URL.
MLA citation example“Is green energy more effective than fossil fuel?”. ChatGPT, Version 3.5, OpenAI, 15 December. 2024,
MLA format in-text citation(OpenAI)

APA Style ChatGPT Citation

Researchers mostly use this style when writing papers on social sciences, such as sociology, psychology, and anthropology. The format was introduced by the American Psychological Association and requires more detailed citation rules for ChatGPT. We recommend using our APA reference generator for your bibliography.

APA citation guidelines recommend mentioning how you used the chatbot in the method section or other appropriate parts. Provide the used prompt and a piece of the generated response. The full conversation can be added in the appendix.

APA citation exampleOpenAI. (2024). ChatGPT (Nov 21 version) [Large language model].
APA format in-text citation(OpenAI, 2024)

Harvard Style ChatGPT Citation

When referencing the AI chatbot under these guidelines, include the author’s name, publication year, title of the work, and the date of accessing the source. If you use direct quotes or paragraphs from ChatGPT, include the page or paragraph number where it can be found. You can try our Harvard citation generator to create an accurate reference list.

Harvard citation exampleChatGPT, 2024 “How to Cite ChatGPT in Different Writing Styles.” [Message number 1234] (personal communication, January 22nd).
Harvard format in-text citation(OpenAI ChatGPT, 2024)

Chicago Style ChatGPT Citation

The Chicago citation style is widely used by publishers of academic journals and books. More specifically, for works regarding social sciences and humanities. Students use this style when writing history, religion, and social science papers. You can try our Chicago reference generator or learn about the Turabian citation style, a subtype of the Chicago style, and generate your bibliographies.

In the Chicago manual, numbered footnotes list ChatGPT as the author, followed by the date of response generation. Next, one lists OpenAI as the publisher, with an optional URL. This style doesn’t advise students to add chat logs to the list of cited works. However, they should mention this whenever editing AI-generated content directly or at the end of the note.

There are four steps to make footnotes for your paper.

Add the phrase “Text generated by ChatGPT, date of generation, “OpenAI,” and the general URL in the footnote when providing a prompt. When citing the same chatbot text multiple times, you can shorten the note to “ChatGPT.” Add a prompt to the footnote if it isn’t mentioned in the text. Finally, if you’re using author-date format instead of notes, put information not present in the text in parentheses.

ACS Style ChatGPT Citation

The American Chemical Society developed these niche guidelines. In the college environment, it’s used in academic papers on chemistry. While the ACS style doesn’t provide rules for citing AI-based texts, there are some suggestions you can use in your research assignments. Instead of citing ChatGPT as a data source, refer to it as a tool.

Vancouver Style ChatGPT Citation

The Vancouver style is popular in scientific research papers in the medical field. It uses a numerical approach that provides additional information about sources. These guidelines don’t offer concrete instructions for citing generative AI tools.

At the end of your text, list the ChatGPT source in the reference list, providing as much information as possible. This might include the title of the conversation, the date it was accessed, and the URL.

Oxford Style ChatGPT Citation

Oxford doesn’t directly tell how to cite Chat GPT content like many styles on this list. Students should use the same system for making footnotes in this style as other content types. The style has them add superscript numbers in the text and notes at the bottom of pages. The latter are numbered sequentially, starting with 1 and continuing throughout the paper. Direct quotes are enclosed with single quotation marks.

Oxford footnote citation templateChatGPT, “Prompt” Accessed Date, [URL]

Oxford reference listDon’t include ChatGPT entries in the reference list.

IEEE Style ChatGPT Citation

Students use these guidelines when working on papers in technology and engineering. Here, they must add the author’s name, the publication date, and the webpage URL. Use “n.d.” in the citations when there’s no publication date. This style has no special rules for citing ChatGPT and related generative AI products, so follow the general guidelines.

IEEE footnote citation template[#] Author (Program Name), response to author query. OpenAI [Online]. URL (Accessed date).
IEEE footnote citation example[2] ChatGPT, response to author query. OpenAI [Online]. (accessed February 7, 2024).
IEEE reference listDo not include it in the reference list.

📜 Can ChatGPT Cite Sources?

Yes, but…

The free version of the OpenAI tool doesn’t have access to the Internet; it works with a restricted amount of data uploaded before January 2022, which messes with the responses. Such limitations cause ChatGPT to give wrong answers, which can be disastrous, especially in fields where new things are discovered daily.

Therefore, you risk obtaining incorrect sources whenever you ask the chatbot for references. The reason is simple: ChatGPT doesn’t address these sources itself; it can only provide the ones it was trained on.

Not having access to the Internet, ChatGPT can even make up some sources. The study about ChatGPT fabrications and citing errors shows that the tool produced over half of the fabricated citations (55%) for the GPT-3.5 and 18% for the GPT-4. At the same time, 43% of the authentic sources included substantive citation errors for the GPT-3.5 and 24% for the GPT-4.

Although it might seem that ChatGPT formulates truthful responses, we recommend checking all the resources the bot gives. After all, because of its limited access to information, it may hallucinate and give inaccurate answers to specific questions. Pay attention to these matters:

⚠️ Authenticity of sources. Double-check every article or other material in credible scientific databases, for example, Google Scholar, Web of Science, JSTOR, PubMed, and others.

⚠️Correctness of citations. Revise the citations provided by ChatGPT according to each style’s requirements. We recommend referring to the official guidelines or using the Free Reference Generator for Students.

However, if you want to avoid double work, there are AI chatbots that make thorough lists of used resources. Check them out in the next section.
