How to cite using APA in the Health Sciences

Elements for AI-Generative Material

Developer Name. (Year). AI Model (version) [Large language model]. Publisher [omit if developer and publisher are the same]. URL

Example

OpenAI. (2024). ChatGPT (Version 3.5) [Large language model]. https://chat.openai.com/

• AI references are based on the APA reference template for software and are suitable for large language models such as ChatCPT or Google Gemini, etc.
• Author: Use the developer of the tool as the author.
• Date: Use the year of the version you used.
• Title: Treat the model (the name of the AI product) as the title. Make sure it is italicized and in title case. Do not include version numbers in the model name (e.g. use ChatGPT instead of ChatGPT-4). Instead, include the version number after the model in parentheses. Different large language models or software might use different version numbering; use the version number in the format the author or publisher provides, which may be a numbering system (e.g., Version 2.0), a date system (e.e., Apr 4 version) or other methods.
• Bracketed text is used in references for brief additional descriptions when they are needed to help a reader understand what’s being cited.  In the case of a reference for ChatGPT, provide the descriptor “Large language model” in square brackets. OpenAI describes ChatGPT-4 as a “large multimodal model,” so that description may be provided instead if you are using ChatGPT-4. Later versions and software or models from other companies may need different descriptions, based on how the publishers describe the model.
• Source: When the publisher name and the author name are the same, do not repeat the publisher name in the source element of the reference, and move directly to the URL.
• Use the URL that links as directly as possible to the source (i.e., the page where you can access the model, not the publisher’s homepage).
