New AI tools are released daily, and university technology teams evaluate these tools to ensure they are accessible, secure and effective. Faculty and staff should ensure they are logged in with their university credentials if they plan to enter institutional data that is above S1-classified data into an approved AI tool. Learn more about institutional data classifications as they relate to AI in the Security and Privacy Statement on Artificial Intelligence statement.

Students should use GenAI tools for coursework only with the explicit permission of each instructor, in the ways allowed by that instructor. For an overview of all available AI tools, visit Ohio State’s AI Tools webpage.

AI "hallucination" is a term used when a Generative AI tool, like Copilot, generates information that is plausible sounding but factually incorrect or completely made up. It's not the same as a human hallucination. The AI isn't "seeing" or "imagining" things in a conscious way. AI's directive is to provide an answer, any answer, to make the user happy. That is why you must take a Use but Verify approach with any AI generated content or answers. It is up to the user to verify the accuracy of the results. Copilot's goal is to be helpful and provide a complete-sounding answer, but in doing so, it can sometimes confidently present a fabrication as a fact.

Microsoft has provided information to assist in the ethical and transparent use of AI.

Responsible AI at Microsoft

Microsoft Copilot is a digital assistant that uses AI to help you with your work. It is available in two versions: Copilot and Microsoft 365 Copilot.

Copilot (formerly known as Copilot with data protection) is a chatbot that uses public online data to provide you with information. It does not have access to your organization’s data or content within Microsoft 365, such as documents in OneDrive, SharePoint, emails, or other data in Microsoft 365.

Microsoft 365 Copilot,  Microsoft 365 Copilot | Administrative Resource Center, is a paid version of Copilot that uses four technologies to generate its natural language. It utilizes the web, large language models (LLMs), and your data in Microsoft 365 services, but it goes one step further by fully integrating into Microsoft 365 applications, such as Word or PowerPoint

To use Microsoft 365 Copilot features in desktop applications like Word, Excel, PowerPoint, Outlook, and OneNote, users must have Microsoft 365 Apps installed and be on either the Current Channel or the Monthly Enterprise Channel. These update channels ensure access to the latest features, including Copilot Chat integration. If you are a MITS customer, you are on Current Channel or the Monthly Enterprise Channel. Some non-MITS units have installed Microsoft 365 using a method called device-based or using a volume licensed key method. If that is the case you will not see Copilot within the desktop applications. 

In addition, users must also be signed into their Microsoft 365 desktop apps using their organizational OSU Campus login of lastname.#@osu.edu(opens in new window) or lastname.#@buckeyemail.osu.edu(opens in new window). Copilot is only supported on primary mailboxes hosted in Exchange Online, and not on shared, delegate, or archive mailboxes. For full functionality, you should have an active OneDrive account, as some Copilot features rely on OneDrive for file access and management.
