This depends on if you are using the artificial intelligence (like ChatGPT) as a tool or as a content creator. Think of the item created by the artificial intelligence (AI) as if it were an author, in this entire guide we have been discussing how one needs to quote or paraphrase an authors work. If you were to take the work of the AI and use it as your own, you are plagiarising.
Even ChatGPT knows that using it as an assignment is cheating. When a professor prompted ChatGPT to "write a warning to a university class about what happens when they get caught using GPT-3 to write essays" the system responded with this:
Attention students: If you are caught using GPT-3 or any other AI tool to write essays or other academic assignments, it is considered a serious violation of academic integrity. This kind of behavior is considered cheating and can result in serious consequences, including failing the assignment or the course, or even being expelled from the university. It is important to remember that the purpose of education is to learn and demonstrate your own knowledge and understanding of the subject matter. Using AI tools to complete assignments defeats the purpose of the assignment and undermines the value of your degree. Please be advised that instructors and professors have access to tools and resources that can detect the use of AI in written work, and they are trained to identify and investigate such incidents. Do not risk your academic and professional future by using AI to complete your assignments. Instead, take the time to learn and understand the material, and complete your assignments honestly and to the best of your ability.
