ChatCDC - CDC Enterprise Generative AI Chatbot (Summarization)

Section 1: Use Case Identifiers

Use Case ID: HHS-CDC-00038
Agency: HHS
Op Div/Staff Div: CDC
Use Case Topic Area: Mission-Enabling (internal agency support)
Is the AI use case found in the below list of general commercial AI products and services?
None of the above.
What is the intended purpose and expected benefits of the AI?
CDC has an internal productivity tool available to all CDC staff which can be used in a variety of ways. This use case covers staff who will be using this general purpose tool to summarize and synthesize information from larger documents such as meeting transcripts, research articles, or other documents. Currently, CDC has internal Generative AI guidance determining how this tool can be used, and individual Centers, institutes, or Offices may implement their own policy to ensure safe and responsible AI.

This tool enables CDC staff to have the productivity benefits of Generative AI powered chatbots without any of the security risks of data uploads to third party tools. Using ChatCDC, Staff can have smaller, more easily digestible summaries to save staff time from reading larger documents if the time to read the full document is not available.
Describe the AI system's outputs.
This chatbot, powered by Azure OpenAI Large Language Models, will generate responses to questions asked by the user, in this case a summary of a larger document. The chatbot's output can then be copied and pasted or manually entered into the appropriate testing process by the staff to ensure any code used from the chatbot's output meets the criteria of the current task.
Stage of Development: Operation and Maintenance
Is the AI use case rights-impacting, safety-impacting, both, or neither?
Neither
