Yes, and as of April 4th, 2023, colleges that use Turnitin's Originality products (like Berkeley) have the new AI Detection tool embedded into Turnitin so faculty and administrators can test it out.
It is totally separate from the Similarity checker and works a different way, and the percentages will be different. Also, this new AI tool's percentage is only based on long-form prose writing sections of the papers, excluding tables, bullet points, and lists:

Faculty may also want to review the resources provided by Berkeley's Center for Curriculum, Instruction & Technology (CCIT) and ask them for help adapting their assignments.
They also may need to reconsider how they determine what is cheating:
Turnitin also has handouts and checklists to help faculty structure assignments in ways that make it harder to misuse AI writing, make clear the policy about AI misuse for your courses, discuss AI detection reports with a student, and encourage ethical use of AI:
