Artificial intelligence platforms (such as ChatGPT)
Massey has a reputation for high academic standards which means people value our teaching and research and future employers value your qualification.
Artificial intelligence (AI) platforms (such as ChatGPT) can be useful learning tools but often use of them may be considered dishonest academic behaviour. You must not use AI tools in an assessment unless your course coordinator or lecturer has given you clear and explicit permission to do so. Using AI tools without permission is likely to result in an academic integrity investigation and being found guilty of an academic integrity breach can have serious consequences such as failing the assessment or even the course.
You can read more about academic integrity at Massey here.
If you have been given permission to use AI platforms, you must still ensure you comply with the Massey Use of Artificial Intelligence in Assessment Policy .
If you have permission to use AI in assessments (such as for developing initial ideas for the purposes of critical examination, or generating text, images or data), this use must be acknowledged.
Note: Be very cautious citing sources generated by AI as sometimes it can create sources that do not exist. It is recommended you personally check all sources generated by AI tools.
The Chicago Manual of Style recommends simply acknowledging in your text that you have used an AI tool to generate content. E.g., The haiku Koru was generated by ChatGPT.
As content generated by AI platforms can only be accessed after logging in, you generally do not include a reference in the bibliography or reference list and it sufficient to simply provide details in a footnote if the use of AI has not been included in your text. The tool is cited in the author position:
1 Text generated by ChatGPT, OpenAI, Feb. 7, 2024, https://chat.openai.com/chat.
1 ChatGPT, response to “Create a Van Gogh style painting of a sunny day”, OpenAI, Feb. 7, 2024, https://chat.openai.com/chat.
The Chicago Manual of Style Online has more guidance and examples about citing generative AI here.
