How to Cite AI Models in Academic Papers (APA, MLA, IEEE)

Why AI Citation Matters

As AI models become integral to the research process — from literature reviews to data analysis — properly citing their contributions is both an ethical obligation and a practical necessity. Major style guides have now issued formal guidance on how to reference AI-generated content in academic papers.

Whether you used ChatGPT to brainstorm ideas, Claude to summarize papers, or Copilot to assist with code, your readers deserve transparency about which parts of your work involved AI assistance.

APA 7th Edition Format

The American Psychological Association updated its guidelines to address AI tools directly. The recommended format treats the AI as a software tool, not an author:

In-text citation: (OpenAI, 2024)

Reference list entry:

OpenAI. (2024). ChatGPT (Mar 14 version) [Large language model]. https://chat.openai.com/chat

APA Key Rules

• List the AI developer (OpenAI, Anthropic, Google) as the author
• Include the version or date of the model used
• Describe the tool type in square brackets: [Large language model]
• Provide the URL where the tool can be accessed
• Include the specific prompt in an appendix if the output is quoted directly

MLA 9th Edition Format

The Modern Language Association takes a slightly different approach, emphasizing the prompt as part of the citation:

Works Cited entry:

"Describe the role of perplexity in AI detection" prompt. ChatGPT, version GPT-4, OpenAI, 14 Mar. 2024, chat.openai.com/chat.

MLA Key Rules

• Begin with the prompt text in quotation marks, followed by the word "prompt"
• Italicize the AI tool name (ChatGPT)
• Include the version, developer, date of generation, and URL
• If the AI output is paraphrased rather than quoted, adjust the prompt description accordingly
• For multiple prompts, create separate entries or describe the conversation scope

IEEE Format

The Institute of Electrical and Electronics Engineers treats AI-generated content similarly to software documentation:

Reference format:

[1] OpenAI, "ChatGPT," https://chat.openai.com. Accessed: Mar. 14, 2024. Prompt: "Explain transformer architecture."

IEEE Key Rules

• Use numbered reference format consistent with IEEE style
• Include the developer name, tool name, URL, access date, and prompt
• Treat AI tools as electronic sources with access dates
• For code generation tools like GitHub Copilot, cite as software

Best Practices Across All Styles

Regardless of which citation style your journal or institution requires, several universal principles apply:

• Disclose AI usage in your methods section: Explain which tools you used and how they contributed to your research
• Save conversation logs: Many journals now require that AI interaction transcripts be available upon request
• Note the model version and date: AI models change frequently, and outputs are not reproducible across versions
• Do not list AI as a co-author: Major publishers including Springer Nature, Elsevier, and PNAS have explicitly stated that AI cannot meet authorship criteria

When Citation Is Not Enough

Some institutions and journals have specific AI use policies that go beyond citation requirements. Before submitting, check whether your target venue:

• Prohibits AI-generated text entirely
• Requires a separate AI disclosure statement
• Has specific rules about AI in figures, code, or data analysis
• Mandates institutional review board approval for AI-assisted research

Looking Ahead

Citation standards for AI tools are evolving rapidly. The guidance above reflects current best practices as of early 2025, but researchers should check the latest editions of their relevant style guides before submitting manuscripts. Transparency is the foundational principle — when in doubt, disclose more rather than less.
