Template for Reference Page
Corporate Name. (year model created). Name of model in italics (date of access or version number) [type of AI, "Large Language Model" is most likely the answer]. URL to the start page of the model or tool.
Indent the second line as usual.
NOTE - This template is based on a late 2023 understanding of AI models. Tools and Agents weren't even a thing at that time. Look for future advice that will require you to mention the "tool" and the underlying "model". Models are things like Anthropic's Claude, Google's Gemini, Meta's LLaMa, or OpenAi's ChatGPT. Tools are things like Perplexity, NotebookLM, Elicit, etc. Tools are built upon, or a specific use of a model. Most current (5/25) models are LLMs (Large Language Models).
NOTE - There may be a time when we will stop viewing the AI as a source and view it as a collaborator, like another student in a group project. If that happens, expect the citations to change to something like a multi-author article or a communication like an email chain.

Requirement
If you are using an AI you need to cite its use. The tricky part is what to include. Because no other person can see the prompt you entered and the entire text generated by the AI, it is helpful to give a part of the generated text and part of what you entered in the prompt. As prompt engineering and natural language prompting become more and more complex, don't try to paste your entire prompt. That would be a waste. Nor should we expect the entire text response, as that can be a 40-page executive summary. No matter what you include, you still must cite the AI.
One a tangent, keep in mind that AI was trained to write fluently not accurately. You must verify the output of the AI. To just accept the output as fact would academically irresponsible. You must still do research.
