The U.S. Department of Health and Human Services (HHS) has reported 271 use cases in the calendar year 2024. This is a 66% increase from the number of use cases the department reported in the previous year. 

“It’s important to keep in mind that use cases come in various sizes and are at various development stages. Out of the 271 use cases, 59 are initiated, 57 are in acquisition and/or development, 35 are in implementation and assessment, 104 are in operation and maintenance,” and 16 are retired,” Steven Posnack, HHS Principal Deputy Assistant Secretary for Technology Policy and principal deputy national coordinator for health IT, said in a blog post.

According to Posnack, the 2024 AI Use Case Inventory goes beyond simple use case summaries, providing detailed information on data, IT infrastructure, internal governance, and more.

Overall, 37 federal agencies in the U.S. have reported 1,757 public AI use cases, according to the 2024 consolidated inventory, available on the Office of Management and Budget’s GitHub repository. In comparison, a list released by the White House last year documented 710 use cases.
