professor here. i set up a website to host openwebui to use in my b-school courses (UG and grad). the only way i've found to get students to stop using it to cheat is to push them to use it until they learn for themselves that it doesn't answer everything correctly. this requires careful thoughtful assignment redesign. everytime i grade a submission with the hallmarks of ai-generation, i always find that it fails to cite content from the course and shows a lack of depth. so, i give them the grade they earn. so much hand wringing about using ai to cheat... just uphold the standards. if they are so low that ai can easily game them, that's on the instructor.
