I rely on written exams that are open book, but forbid any use of computers and smartphones in class.
The university insists that homework can't be optional, but it lost its meaning. I've tried to explain to my students that it's in their interest to think about home assignments on their own, but the majority will obviously use gen AI, and it's such a waste of time to check and grade LLM output.
I just had an experience where all students were given "sample problems" to try at home and prepare for the written test. Many of them just dumped the document into an LLM, asked it to produce some "exam guide", and showed up with that thing printed out, asking me during the test to explain what LLM output meant.
It seems like the university also has many people pushing for AI use for everything, but I teach basic stuff where the goal is to make students think on their own and digest some fundamental ideas, LLMs can produce perfect solutions, but relying on them is pointless.

How about cutting out the open book so that the students who don't study and to their homework actually fail? When I was in school many years ago "open book" was only used for special ed students and others who couldn't carry a regular academic workload. Homework was assigned, but our grades were determined solely by testing our mastery of the material. If you could master the material without doing the homework or showing up for class on non-testing days, more power to you. College has become more like kindergarten with all of the hand-holding.

This was too long ago for me to remember the details of but, just making an example here, we might have had a course on homogeneization of elliptic problems using a model PDE with a div(A grad u) term throughout, and then the exam was about a PDE with a curl(A curl u) and some other added terms.
Notes carry the method and theoretical tools but you then still need to apply them to a new problem.
So, if anything, our open book exams were harder and a better test of understanding and mastery. You couldn’t rote your way into a good grade.
