The official APA Style website has guidelines for citing content generated by AI: Citing Generative AI in APA Style

General Format for Chats

(AI Company Name, year)

References

In APA Style, the four elements of the reference list entry are:

• Author: The company who developed the AI tool. For example, the company, "OpenAI," is considered the author (not "ChatGPT")
• Date: Reference the specific year, month, and day on which the chat occurred or concluded.
• Title: The title is the title of the chat, formatted in italic sentence case, followed by a bracketed description about the nature of the source. For example, "[Generative AI chat]." The wording within the square brackets is flexible so choose the wording that "best convey[s] the information readers need" (per Section 9.21 of the Publication Manual; APA, 2020, p. 292). The title of the chat, in most cases, can also be edited so consider editing the title within the AI tool to be as helpful and descriptive to your readers as possible.
• Source: The URL of the chat.

AI Company Name. (year, month day). Title of chat in italics [Description, such as Generative AI chat]. Tool Name/Model. URL of the chat.

Example

(OpenAI, 2025).

OpenAI. (2025, September 19). Post-secondary history topics [Generative AI chat]. ChatGPT. https://chatgpt.com/share/68cdb46c-4254-8001-9bb9-e024036dbaac  

Citing an AI tool in general can also be done. According to the APA Style Blog, you should "[c]ite an AI tool generally when it would be unhelpful, unethical, or otherwise inappropriate to cite a specific chat - as well as when you want to point to the existence of the AI tool but not necessarily cite specific information from it."
