APA has published a page tells you how to approach citing AI.
APA notes that their examples are meant to cover the use of generative AI tools like ChatGPT for functions such as creating some text, or facilitating research, not to write the full text of a paper. They also note that the use of generative AI should be described in the methods section of your paper. APA does not list generative AI tools as an author, but the creator of the generative AI tool may be listed as an author, such as OpenAI for ChatGPT in the example below.
Here is an example of a reference:
OpenAI. (2023). ChatGPT (Mar 14 version) [Large language model]. https://chat.openai.com/chat
Note that this example does not include the formatting required for your paper such as hanging indents.
Go to APA's How to cite ChatGPT to get all the details.
Meanwhile, as a student you should know that your instructor or institution may have different or additional criteria for the use of generative AI in your class.
