Security, Privacy, Data Classification Usage Guidelines

UF provides this service to allow you to analyze your documents using different language models while keeping those documents secure within UF servers and contracted vendors.  At this time, UF does not permit the usage of restricted or sensitive data with this service. Users only have access to their own datasets and conversation history. When interacting with the language models hosted by vendors, your messages and subsets of your documents will be sent to a LLM instance provided by Microsoft or Google.  All data handled in this fashion is covered by our existing agreements with Microsoft and Google.  None of this data contributes to training the large language model. No data is retained after deletion.  If you have uploaded a file by accident, deleting the file or conversation will completely remove it from the system.

*Accessing Navigator AI off-campus requires UF Gatorlink VPN Service.

Language model preset parameters

Parameter	Description
Model	Select the model like gpt-3.5-turbo that will be used for generating responses
Custom Name	Optionally provide a custom name for your preset. This is the name that will be shown in the UI when using it
Custom Instructions	Define instructions or guidelines that will be displayed before each prompt to guide the user in providing input
Temperature	Adjust this parameter to control the randomness of the model’s output. A higher value makes the output more random, while a lower value makes it more focused and deterministic

Frequency Penalty	Use this setting to penalize frequently occurring tokens and promote diversity in responses
