AI led to “consistent and significant improvements in the speed,” of law students’ work on common legal tasks, said Daniel Schwarcz, a University of Minnesota Law School professor and one of the authors of the study.

Using AI enhanced students’ speed by as much as 32%, according to the draft paper, posted Wednesday. While AI use didn’t harm the quality of the work, its benefits varied.

The legal profession is beginning to grapple with generative AI’s impact, including how firms will have to adapt—or even abandon—the billable hour when technology-powered legal work goes much faster.

For clients, “the expectation should be already, that either you’re paying much less or you’re getting much more,” Schwarcz said. “If that is not consistent with experience, then I think clients should start asking why not.”
