Citing Artificial Intelligence (AI)

The use of ChatGPT or other AI tools in assignments should be discussed with your instructor. As a general rule, if you are incorporating any information from an AI tool into your research assignments, you must cite the AI tool or the information that the tool is directing you to.

For more information about ChatGPT and AI, please visit the Libraries' Artificial Intelligence guide.

For faculty/instructors looking for further teaching support and development around ChatGPT and AI, contact CTLE at CTLE@syr.edu
